• The airPort Extreme (2007) and Time Machine

  Hi all

  I read the info "how to ask a good question" and apparently you need details. I'll try and be concise but informative with my problem. It has been a long journey to get to where I am, but hopefully, with a little help from this amazing community, I can get to my destination.

  Task

  To produce a backup solution Time Machine for the family spending as little money as possible and using the BRIC and broc, I already have.

  Equipment available

  I have a House with some ethernet cables for most rooms that through switches to allow a variety of, most entertainment devices to communicate. It is:

  1 x NAS/Media (ReadyNAS Duo v2) server,

  2 x TV (Samsung),

  2 x TEU (Beyonwiz),

  2 x Apple TV (a 2 nd generation the other is the latest version)

  2 x DVD players,

  1 x iMac.

  2 x 8-port switches,

  1 x 16 switch ports,

  1 x AirPort Extreme (2007).

  1 x Airport Express (age unknown but older than the extreme)

  1 x Fritz! Box 7490 Modem/Router

  Courses in place

  All the associated TV stuff are connected in 2 rooms through ethernet via switch 2 x 8 ports switch 16 central port and then to the Fritz! modem/router box.

  There are also all the usual WiFi going on with mobile phones, iPads and laptops.

  Remarkably, it seems just to work!

  However, I want to add some backup data on our computers. I tried to do by using the ReadyNAS as it is supposed to support Time Machine, but I can't it to appear as a backup destination. So, I thought, as I have AirPort Extreme, I add it to the network and attach a USB HDD for Time Machine since it is supposed to be easy. However, I've been home for hours and cannot make the HARD disk appear in system preferences/Time Machine.

  I plugged the Airport Extreme in one of the switches 8 port said to create a wireless network with the same details as the Fritz! The box according to another article of the support (Airport Extreme wired AND expand network - need of entry). Airport utility shows me Wi-wired connections and seems to work.

  I look at the AirPort Extreme disks tab and can see the attached USB drive here. However, it does not appear as a choice of drives available for backup in Time Machine preferences. I tried 2 different discs with the same result.

  The Question (finally)

  How can I get Time Machine preferences to show the USB disk attached to AirPort Extreme as a valid choice for backups? If anyone can give me a little help in the right direction, I would be very grateful.

  Thank you for reading this,

  Grant

  Unfortunately, the key here is that the version of AirPort Extreme you have does not officially support Time Machine backups on a drive to the USB port of the device.

  The only version of the AirPort Extreme, which will officially support Time Machine backups on a drive in the USB port on the airport is the 802.11ac current version that looks like a "tower". Older versions of 'flat and square' of the AirPort Extreme don't support Time machine with a USB drive attached.

  To check, please see "Time Machine in charge of USB drives" in this Apple support document... AirPort base stations: discs on USB - Support Apple

  Support for time Machine to USB drives

  OS X Time Machine supports compatible USB drives encrypted, related to the time Capsule (802.11n and 802.11ac) AirPort and AirPort Extreme (802.11ac).

  Given that the average life of most wireless routers lasts about 5 years, and your AirPort Extreme seems to be about 9, your AirPort Extreme did very well for you... much better than the average. It might be time to start thinking about a replacement who will be responsible for backups Time Machine... either a time Capsule (i.e. an AirPort Extreme with a built-in hard drive) or another AirPort Extreme.

• Network slow 2nd Airport Extreme AC reviews

  Hello:

  We have two units of the Airport Extreme AC. One of them (the principal) is connected to our cable modem, and the other (secondary) is connected to the primary via ethernet.  The secondary AC unit allows to extend our networks wireless in another part of our House.  We used the Airport 6.3.6 utility to configure both units in HQ.

  We have three different wireless networks.  One of them is our 5G, the other 2. 4 g, and the third is our network of comments.  5G and 2.4 G networks have the same password, and the guest network has a different password.

  Everything seems to work perfectly, with the exception of the network invited on our secondary AC unit only.  It is very slow; less than 2 Mbps using speedtest.net.  All our other wireless networks (including comments on the primary AC network) to the Internet from 100 Mbps to 200 Mbps speeds.

  A few more details.  Our secondary air conditioning unit is configured in Bridge mode, and it's 'creation' (not extending not) our wireless networks.  This secondary unit was created in this way by the Airport utility.

  Anyone has an idea why our network comments on the secondary AC unit is so slow?

  Thank you!

  It is a problem with the design of the network.

  Do not know what to do about...

• Why is my slower than wifi ethernet download speed when using the airport extreme?

  Hi all

  This is my first post here, so please bear with me. I currently own stunted 2011 Macbook Pro 13 inch and an extreme A1521 from the airport. My ISP has promised 50Mbps downloading and sending 10 Mbps. When I connect my MPro via ethernet/wi-fi to my modem I get as promised. When I connect my MPro via wi - fi to the extreme I get 48Mbps download download 9Mbps and it's ok. However, when I connect my MPro via ethernet to extreme I get 8-9Mbps download and 9Mbps. Anyone know how to fix this?

  If you check the 'fine print', your ISP has promised "up to" 50 Mbit/s and 'up to' 10Mbps.  The ISP might provide more than that during periods of slow activity, like the days of the week during the day, but much less during evenings when there are many more users on the Internet.

  When I connect my MPro via ethernet/wi-fi to my modem I get as promised

  I assume that you meant to check the Ethernet connection, you disable WiFi on Mac when you do this. And unplug the Ethernet cable when you check the speed of the WiFi, correct?

  If so, this tells you that the Ethernet port to both the modem and the Mac work properly, and WiFi work correctly as well.

  When I connect my MPro via wi - fi to the extreme I get 48Mbps download download 9Mbps and it's ok.

  If this tells you that the Ethernet connection between the modem and the AirPort Extreme works correctly, and wireless works fine on the AirPort Extreme.

  However, when I connect my MPro via ethernet to extreme I get 8-9Mbps download and 9Mbps.

  Well, you know that the Ethernet connection between the modem and AirPort Extreme works because you can register 48 Mbps Wireless.

  Thus, the possibilities are narrowed to two elements at this stage:

  (1) the Ethernet cable is defective or making intermittent contact. Try another Ethernet cable, to ensure.

  (2) If you have turned off AirPort Extreme and rebooted several times, and you know that the cable between the Mac and AirPort Extreme works properly, then you have reduced the question down to the Ethernet on the AirPort Extreme, which is probably defective switch.

  If you have not already done so, try other ports Ethernet on the AirPort Extreme.

  As a last resort, perform a reset material on AirPort Extreme and put up again. To perform the Hard Reset... power on AirPort Extreme for a few minutes, then hold it pushed in the reset button on the back of the unit (near the AC power plug) for 7-8 seconds and release. Allow a minute for the AirPort Extreme restart orange light flashing slow.

  I once went through two consecutive airport extremes with the same question about 8 months ago, so it can happen.

  If you're still having problems, then it is time to take the AirPort Extreme of Apple Store... If you have one near you... or contact the Apple Support directly by clicking on 'Contact the Support' in the upper right area of this web page.

  Good luck!

• Slow wifi transfer rates with Airport Extreme network.

  I have an Airport extreme Rev 5 and am trying to transfer files between 2 Mac on the network. Everything works fine, but the transfer speed is only about 2.5 meg per second. Should get more than that?

  Everything works well, I get my full bandwidth from my ISP (11.8 Mbps) when downloading via wifi, it s just during the transfer of files within the wifi network that things are slowing down.

  Thanks for any help

  Tim

  Wireless is inefficient when you double jump... This means that... both computers are transfer of files via the Wi - Fi because wireless deals actually double the packages... So he immediately reduces speed by 50%.

  Let us ensure that we are using right units first.

  1. your download from the internet is measured in bits per second... Please use b for forests.

  2. your file transfer is measured in bytes per second... Please use B for bytes.

  So, if you look at the monitor of activity... a copy of computer file wireless to NAS (ethernet) ran at 38-40 MB/s

  

  If I transfer to another computer that is also the wireless speed would be halved. Or worse... (see below, even with AC wireless is far worse) depends on the slower links.

  So how do you measure the speed of file transfer and is it bits or bytes per second?

  What is the speed of connection on each computer.

  Hold down the option key and click on the fan wireless.

  

  You can see that this computer has a 450Mbps link speed... It will never transfer files to that more than half, but you wait for connections at full speed to get the best links.

  My new computer...

  

  So if I transfer the computer file to another, it looks like this.

  

  Even with that wireless, it's much slower than the SIN that has ethernet and spinning drive... The computer has SSD.

• The Airport Extreme has download slow unless its an apple product

  I need help.  I have an Airport Extreme router.  I run a HP all in one office, two smart TV, Wii and two boxes on my router.  Not all work at the same time, nor do two pass at the same time.

  I check my router on Mac speed: 100 Mbit/s easy.  I check my iphone: 100 Mbps.  I checked the HP desktop computer: 30-50 Mbps.  I haven't checked the Wii, Smart TVs do not open always Netflix, my boxes go slow and buffer for long periods of time.

  There must be a setting that does not allow non-Apple products to run more slowly.  I pay 100 Mbps and expect to receive 100 Mbps on the Airport Extreme for all products, not just Apple products.

  What I could try or have I missed that should be done so all non-Apple products get the speed of download and Apple products?

  I called support and they had me change the channels in the configuration of the Airport Extreme wireless.  That did not help.  I changed them back and now the iPhone runs slower, below 50 Mbps upload when you fill out a speed test on www.speedtest.com.  I'm sitting in the same place.  It makes no sense at all.

• Loading slow web page and with Airport Extreme connection speeds

  About 5 days ago, I noticed a significant slow down the loading of web pages. In some cases, I see a blank white screen for up to a minute before the page is loaded. In others, the page never loads at all. And sometimes they load very quickly as expected. This happens with my iMac that is connected to a router via ethernet, as well as my Macbook Air connected via Wifi to Airport Extreme.

  I have a high-speed internet connection by cable Comcast/Xfinity: Blast 250Mbps.

  I tried to connect my iMac directly on the model of cable (Arris Surfboard SB6183), and there is no problem. Download speed was 30Mbps 300Mbps and upload.

  Then, I plugged my Airport Extreme router again and connected the iMac to the router via Ethernet. Download speed dropped to 100 Mbps!

  This suggests that the problem may be with the Airport Express. It is not a wireless problem, because as you can see the download speed went from 300Mbp/s connected directly to the model 100 Mbps when connected to the Airport Extreme.

  How do I troubleshoot/fix this?

  One last thing: I did a speed test with my Macbook Air that is connected via Wifi and the Airport Extreme router. Download speed dropped to 35 MB/s.

  Direct connection to the modem is so very fast, suggesting the internet connection Comcast isn't the issue. Speed falls even with ethernet to the Airport Extreme router connection, then decreases even more with the Wifi connection.

• the Airport extreme, giving a slow wifi connection

  Hello

  I've got my download speed of 200 Mbps cable company. I checked a good signal by plugging directly in he back of the Modem (to remove the photo Airport extreme wifi.) ... I have 221Mbps actually...

  However, once I'm going to plug in the Airport Extreme and text my speed on wifi, I get only between 24 Mbps or max after several trials of 54 Mbps on download... I should get just under 200 Mbit/s because of the normal fall through wifi... However, not to the extreme I loss I get...

  Tuesday Apple Support has helped me to perform a reboot of the router and I have been good to get 198Mbps... It is here 2 days later and I'm back down to 24 Mbps...

  I tried to redo the reboot: unplug the unit, hold down the reset button, then while holding down the reset button, add power on and continue now stuck until it flashes yellow... But curiously, after it flashes it goes straight to the green... (never asking me to airport utility to add a password)

  My Wifi speed stink...

  What continues with this device... anyone have recommendations?

  I already proved the cable line and the modem (with the support of motorola)...

  Thank you

  Most likely you have a faulty AirPort Extreme. Please ask Apple to replace this unit for you.

  If you wish to renew a reset, follow the instructions very carefully:

  Turning off AirPort Extreme

  Wait 7 - 8 seconds

  Hold the first reset button... and hold in an additional 7 to 8 seconds while simultaneously you reconnect the power on the AirPort Extreme.

  Release the reset button to zero after the period of detention

  Allow a minute for the AirPort Extreme restart. The light will be Orange fixed for 15-20 seconds about, then turn to flashing orange slowly after about 30 seconds

  A slow amber flashing light... about once per second... confirms that the airport has been reset and you can set it up again.

• Airport Extreme and Airport Express remove blackheads effectively.  The Eeco seems a better solution.

  Airport Extreme and Airport Express do a bad job to expand the WiFi connection in a House.  The Ethernet port on the Airport Express doesn't seem to work.  The Eeco product seems to have done a better job to extend a Wi - Fi network in a home.

  You posted your comments as an issue. You have a question or a problem that you want to get help related to Apple network so that we can try to help you to?

• provider changed vague Qwest and now one device connects to the net.  Seems to not be recognizing the airport extreme.  Patches?

  Decided to change providers.  Network domestic fine fixed by extreme airport which has been consulted by 9 apple devices and windows device.  After the wave was installed yesterday, the only device able to connect is the cell that was active at the time of installation.  Is this a problem with my airport extreme or vague does not not with mac?  All the patches would be appreciated.

  After the wave was installed yesterday, the only device able to connect is the cell that was active at the time of installation.

  Sounds like Installer connected your laptop directly to a modem to put in place the new connection.  If that's what happened, then the modem will recognize your laptop, but it will not recognize the AirPort Extreme, then it will appear as if only your laptop can get a connection.

  The modem and AirPort Extreme should probably be reset and then set it up again. We'll know more soon.

  Can you provide the number of brand and model of the modem that was shipped with your service?

  What operating system uses the laptop?

• Addition of AirPort Extreme allows a Local network behave strange

  Hello

  At the moment is have this setup at home.

  DSL-> provider Modem/Router-> LAN-> airport of Time Capsule

  The airport Time Capsule is the generation model current 5th A1470 of running in mode Bridge with the router form my provider and implements a wireless network. It all works very well, but in my office working there WiFi coverage is a little low is a desire to grow with another airport.

  This is the configuration of the construction:

  DSL-provider of Modem/Router-> LAN-> airport of Time Capsule-> LAN-> Airport Extreme >

  Airport Extreme is the generation model 1408 5th also running in Bridge Mode and extend the wireless network. When I perform this configuration, the problems start. All devices bad connection to the internet, features are added several times on the network (also the Airport express are added some time because it appears with a (2) after East), in Airport utility, I get constantly disconnected status and it is very difficult to resolve, because I lose the connection even if I'm hard wired to the airport. I can also access devices that have a static IP address as the same router (192.168.1.1) or my home server. Thus, it seems that my local network is malfunctioning.

  When I unplug the Airport Extreme, everything works well again. I searched but not found this problem.

  Thanks for the help.

  Airport Extreme is the generation model 1408 5th also running in bridge and extend wireless networkMode.

  You can NOT extend wireless with the AE plugged into the TC.

  Your choice of plug in ethernet is good.

  Your wireless installation must be to create a wireless network... you can use the same name as the TC's wireless or different... It is totally up to you.

  What you did is due to a loop with the connection by both wireless and ethernet.

  If you want to use extend wireless... much slower option... then you disconnect the ethernet AE of the TC... If the connection is purely wireless.

• Network configuration of Roaming Wifi problem I just bought an Airport Extreme and I intend to use it as my router

  I just bought a refurbished Airport Extreme and I intend to use it as my router & combine with our old time Capsule of existing one to create a roaming Wifi network.

  The new Airport Extreme (renovated) is in my studio/Office - directly connected to our internet broadband wireless (WAN port)

  Our small ethernet is connected to my iMac [mid 2010 running OSX 10.11.5] & a PC and extends up to 2 other domains through an ethernet switch.

  This configuration works very well, our internet speed has improved slightly - better than our old T-Link router bit.  WiFi available throughout the House - better on one side.

  Time Capsule (2 TB) is connected by ethernet on the far side of the House, offer backup Time Machine and strong Wifi to this area.

  This time Capsule was an existing installation that went perfectly with the T-Link before I bought the Airport Extreme.

  I used the Airport utility to set everything up and it seems to work.

  The problem is:

  Combines the Capsule and extreme connected & active, the Internet gradually slows down and grinds to stop. -Wifi seems to follow suit, but is much more gradual.

  If I disable the Time Capsule, the internet connection is back to normal, Airport Extreme Wifi signal is strong and extends to almost all areas.

  I got to the departure of the two units configuration problems, so I reset both factory default and from that moment managed to do all this work - with the exception that the internet connection slows down.  Whenever I visit a different web site, it takes more time to load/link upward.

  I spoke with our ISP, the link to our tower is solid. The technology suggested that I put Wifi on each unit to use a different channel (2 frequencies & several channels each available).

  So far, this has not resolved the problem, I will continue to make adjustments.

  I googled this - most of the answers are not to date - usually 2012, 13, 14. and not directly related to my situation.  But I will continue my search.

  I'd appreciate if anyone here has any suggestions

  The new Airport Extreme (renovated) is in my studio/Office - directly connected to our internet broadband wireless (WAN port)

  What is the number and the model of the modem or modem/router that your ISP has provided you?

  Should we assume that you use a Mac with the help of a current or recent operating system?

  If you get out of the Capsule of time and leaves disabled for now, the network AirPort Extreme continue to run at full speed for a few hours and not slow down?

  We ask these questions because we must first confirm that the AirPort Extreme works properly until we can begin to troubleshoot the connection to Time Capsule.

• Airport Extreme network orientation parameters

  Here is our network (diagram below) configuration:

  Internet is available through a pass by modem cable to the Sonic Wall set with a static IP address. The wall of sound, we have a port to a point of cradle that is not with a static IP and gives on a totally different range of the IPS via DHCP to our POS. Another port of the Sonic Wall, I had going to the WAN port on our new airport extreme. I have a switch with some control machines connected to the Airport extreme via an ethernet cable. All devices connected via wifi or hard cable with Airport extreme are placed for IPS via DHCP.

  I am trying to configure parameters on a new device extreme airport our Wi - Fi to my company. We recently had some problems of internet connectivity for a minute or two at a time and I wonder if it could be some sort of conflict of IP address or if it was just a failure of the internet that did not affect the status of the modem lights cable (all were green = connected). Brief history: the most extreme airport on a port of our Sonic wall with the airport extreme is default DHCP and NAT (he gave me the orange light, and he suggested that I put it in Bridge mode). Internet in all of our network seemed to work very well, so I just left it alone.

  30 days later we have a brief interruption in internet connectivity with our credit card processing POS two days in a row for a minute or two of. After the second case, we shut down the extreme airport just in case that was causing our problem. I had a technician COMPUTER down and he suggested I put the airport with a static IP (x.x.7.80) outside the range of IP addresses of our wall router Sonic DHCP-range (let's say it was x.x.7.100 - x.x.7.252) he has been giving and then configured the network settings for DHCP LAN only Airport (I used x.x.7.10 - x.x.7.70) with a range that doesn't overlap the IP of the Sonic Wall range. Part of the confusion, I had during the configuration of the airport was if I needed to plug in our Sonic Wall static IP address in the 'router' address and if I needed to use the DNS servers that appeared in the Sonic Wall settings (I thought he was shooting at those of the cable company). After you make these changes, I got a green light on the airport and the connection was working fine when tested. The next day, we had another interruption of connectivity where our treatment card and internet from WIFI got interrupted. I unplugged the power of WIFI and it seemed that our POS network has begun to process cards normally again.

  The point side cradle of the network is to grasp what IP the sonic wall gives him and give the address on a completely different system that is used in the other part of the network. Another question would be if I can just put the Airport extreme to DHCP mode under the 'Internet' parameter and go to the bridge on "Network" setting Mode I don't know how the bridge Mode would affect our network. I'm not wanting to do anything on the side POS (point of cradle) which is rather difficult with someone like me who is not an expert. Any thoughts are appreciated to help me resolve this issue.

  

  Brief history: the most extreme airport on a port of our Sonic wall with the airport extreme is default DHCP and NAT (he gave me the orange light, and he suggested that I put it in Bridge mode). Internet in all of our network seemed to work very well, so I just left it alone.

  There are two schools of thought on this.  The traditional method (better, in my opinion) would have the AirPort Extreme, put in place in Bridge Mode... Since you already have another router... (the Sonic Wall device which is upstream of your network)... providing routing services.

  Although you might be able to make a network work well with two different devices acting both as of the routers on the network, it complicates things, adds another firewall to the network, and also produces a base called Double NAT network error.

  Sometimes you can get away with a Double NAT error on a simple network, but the double layers of NAT may cause some unpredictable problems. The usual problem is slower navigation, or you will not be able to access some Web sites.  Network devices may not communicate reliably, or communicate at all in some cases.

  This is why Apple software configuration you advise to set up AirPort Extreme in bridge... Mode to fix the Double NAT error. This type of configuration simplifies your network... Since one device will put a router... not two.

  In recent years in particular, we have seen some tips on forums that goes against the rules of traditional networking.  These people that it is OK to have two devices both try to act as routers to the same network... and to 'ignore' the Double NAT error on the network.

  It's interesting tips, since the Apple software advises you avoid having a Double NAT on the network... and some advanced features like Back to My Mac specifically Apple advise to avoid a Double NAT error on the network.  If you have a console online game and you want to play interactively on Internet, you already know that a Double NAT error will not allow this.

  My suggestion would be so... If you have not already tried it... to set up the AirPort Extreme in Bridge Mode.  Apple calls this setting off (Bridge Mode)... which simply means that routing services are turned 'Off' Mode bridge.

  You can still assign a static to AirPort Extreme IP address, if you want, but the devices that are connected to the AirPort Extreme will receive the Sonic Wall router network IP addresses... Since the airport acts as a simple device to "go" when he returns and in Bridge Mode.

• Connectivity with AT & T-Motorola 3360 and Airport Extreme problems

  Bought a new extreme-Airport (7.7.3) to replace my old AE after 9 years of service.  The installation procedure, but could not get the airport to connect with my modem (Motorola 3360).  Called at & T and they crossed put me the modem in Bridge mode and which seemed to work.  But only temporarily (about 5 hours).  Restart the modem and the airport was not working.  Troubleshooting I tried to plug my MacBook directly into the modem, but even the computer couldn't get an internet connection.  Another call to AT & T and they reconfigure the modem to their end.  After 90 minutes and try everything they could, they have finally admitted defeat and told me that they could not solve the problem.

  However, after a fairly exhaustive search of this forum, seems to be two issues that many people is with Airport extreme.  One is that the modem (in this case a Motorola 3360) is perhaps not fully compatible with the airport.  The AT & T support person was not aware of this until I asked about it, so she did a quick search and was rather surprised to see that there is a lot of people having problems with the Motorola Modem.  She told me that they use no more Motorola modems but ship the 6200 of Netgear.  "All know issues?", I asked.  She sought and, to his surprise, even once, there was.

  So, first question.  Does anyone know a modem that is compatible with the airport or use one that they had to limit problems with?

  The second question prevailing seems to be with the IPv6 protocol.  Anyone know if there are problems with the AT & T IPv6 protocol and the most extreme airport?  I did not disable IPv6 yet to see if that helps.  I thought I'd ask here first.  Couldn't find anything on the AT & T site.

  When I return from the road (great place to go to get away from technology) I will make a new round of full power of all the components and try Setup again from scratch.

  Any ideas or suggestions would be greatly appreciated.  Miss all know profanity.

  Thank you.

  Any other relevant information: 6.3.1 the utility Airport, Airport Extreme 7.7.3, MacBook Pro running 10.8.4, modem Motorola 3360, AT & T high speed DSL, shoe size 11-1/2 wide.

  When you have configured the 3360 as a 'bridge', this would mean that the AirPort Extreme should then be put in place to provide the PPPoE connection service. The airports are not known for their reliability in this type of installation... no matter the type of modem that you can select, so I drop this method as a connection option.

  If you want to keep the 3360... and you have time to experiment... then you can set the 3360 to its original default settings and configure the router from the airport most convenient to connect using DHCP in router Mode of DHCP and NAT.  That will produce what is called a message Double NAT, but maybe it's not of concern on a simple home network, and Apple provides you with the option 'Ignore' the Double NAT, so the airport will display a green light instead a light orange blinking slow.

  You need to try this configuration for a few days to see if the Double NAT will be a problem or not, because it is not possible to predict the effect of a Double NAT on a network... you have to test a few days see how things behave.  If this configuration works well, for you, then you can leave it as what.

  Please note that I do not recommend this type of installation, just suggesting it as an option this work could , if you want to keep the 3360.

  How Double NAT affect IPv6, I can't tell, since I did not use att for several years, and I'm not familiar with their implementation. On wired, IPv6 works fine on the airport with Comcast and Time Warner.  We can provide these parameters for you if want, but have no idea how well... (or if)... they will work with ATT.

  If the installation of Double NAT does not work, your best option would be to go there and get a modem/router or gateway to ATT device and then set up the most convenient airport in Bridge Mode works correctly with the modem/router ATT.  You will turn on the routing of ATT function in this type of installation, but the airport can also produce a signal from the wireless network that you can use.  The modem/router ATT will also provide a wireless signal that you could use for guests, or disable the feature, if you do not need two wireless networks.

  This may also be the best option if you want to configure IPv6 as IPv6 of ATT service must be compatible with the modems/routers and gateways.

• 2nd airport Extreme not found in Airport utility

  I recently replaced an Airport Extreme 6 years with a new one. The former we worked, but the range of its signal seems to have declined, so we replaced.

  Now the news is up and running without problem. And I would take the old and use it to extend our network. We already have an Airport Express Terminal to expand the network, so this would add another node.

  I moved to its new location and plugged the power cord. It shows the yellow flashing light. However, the old Airport Extreme does not appear in Airport utility. Screenshot attached. There is nothing in the section other devices Wi - Fi.

  

  ZeroOne_nomap-2 is my new base station. AirPort Express of Sunny was already part of the network. The old base station does not appear.

  Any ideas?

  You must reset the 2nd Gen AirPort Extreme back to default settings, before it can be put in place to expand the network.

  Temporarily, to locate the 2nd Gen airport near the new AirPort Extreme

  Turn on the 2nd Gen airport a few minutes

  Then hold down the reset button on the back of the airport for 5 to 6 seconds then release

  Allow a minute for the airport restart to a slow, flashing amber light status

  

  Now click the WiFi icon at the top of your Mac.

  Look for an announcement of the new AirPort base station

  Click on AirPort Extreme, just below this list

  

  Who will get the "Wizard" configuration running. It will take a few seconds to display a screen that looks like this, except that you can see your devices and the network name.

  Type a name you want to call the 2nd Gen airport

  Click next

  

  The wizard will set up everything for you. When you see an installation message, click done

  Now, turn off the power and pass the 2nd Gen to its new location where it can receive a strong signal from the AiPort Extreme 'hand' and turn on the 2nd Gen airport
