Airport Extreme intermittently lose network signal

For several days, I repeatedly lose my network signal.  I spent an excessive amount of time troubleshooting including going so far as to have a comcast tech come by today, but it's a bit like going to the doctor... When the doctor walks in the room, all of a sudden all the symptoms disappear.  Anyway, has dropped signal, network cannot be found, restart the modem and the router on a regular basis.  some time, restart allows the devices to the network.  Sometimes it doesn't.  And when that happens, it is not compliant and will lower it again anywhere from immediately or several hours later.  Comcast claims signal input in an apartment is good as well as the modem is good.  They think it is my Apple Extreme router.  However, the same missing network behavior occurred even when I bypassed the router and used a direct connection to the modem via ethernet.  For example, if the signal coming from the wall is good and the modem is good but I have the same problems even if without going through the airport, what happens?  Hope that someone out there more knowledgeable and patient I can sort this out.  I am happy to buy new hardware but want to be sure, that I need.  Comcast, recommended, of course, I get a new modem.  Motorola, of course, said that there is nothing wrong with the modem.  So now, I go to the Apple people to evaluate the remaining product that is Apple.  Thank you.

However, the same missing network behavior occurred even when I bypassed the router and used a direct connection to the modem via ethernet.

Is your modem or ISP...

The problem occurs intermittently... the curse of living in any repair technician. If they can see what is happening, then they can work on that.

You have no choice but to continue to pursue to the ISP.

For now use mac plugged directly on the modem... and as soon as he left the ring and say that it does not work now.

This modem do you have?

Certainly, we have experienced problems with the Modem Motorola... SB6141 is the top of the list.

The problem with the airport is well known... but I would have thought that the live Mac should be ok...

In any case a new modem is not expensive and worth it.

The zoom seems the best solution... check that it is on the list of comcast.

Zoom modem.

  • Airport Extreme with guest network configuration

    Does anyone have a suggestion on how to implement it properly?

    There's the rub.  Since you have a router supports DHCP and NAT services to the network 'upstream' extremes of the airport, the airports must be configured in Bridge Mode to avoid Double NAT error that occurs when you have more than one router on a network.

    Unfortunately, the network comments feature does not work correctly when the airport is in Mode Bridge connected to another router.  The 'main' or private network works OK, but 'guests' will not be able to access the Internet.

    The only way to do what you want would be to configure things wrong by...

    (1) connect to an AirPort Extreme to the switch and configure it as a router to "create a wireless network" using DHCP and NAT.

    (2) linking the second AirPort Extreme for the first AirPort Extreme... not to the switch... and implement the extreme second "extend using Ethernet.

    Since you will have a Double NAT on the network, there is no guarantee that things will not work properly. Sometimes you can get away with a Double NAT error on a simple network, but it can cause difficulties of communication between devices on the network and the difficulties with Internet connections as well.

    If you have a console online game and want to play interactively on the Internet, the Double NAT error will not allow this to happen.  Similarly, if you plan to use Back To My Mac or Port Forwarding for access over the Internet to remote devices, the Double NAT will allow these connections probably not happen.

    We do not recommend a Double NAT Setup, but we have some ideas on how to do it. There of probably no harm in trying the Double NAT configuration if you have the time and are willing to experiment to see if it peut work for you, I'm sorry, but there are no guarantees here.

  • Impossible to extend the AirPort Extreme wireless network

    I have a wireless network set up with a time Capsule airport 4th generation.  I'm trying to take my old AirPort Extreme wireless 3rd generation. I have double. Kettle has implemented, but I get the status message on the extreme that it cannot extend the network.  I can get a strong signal on my iPhone from the point that I have placed extreme itching so I'm close enough to the time Capsule.

    Could I use a connection by current bearer through my home wiring to the extreme and extend it like that?

    Does anyone have any suggestions?

    Please follow these steps closely and report on your results.

    Power off time Capsule airport.

    Wait 10 to 15 seconds

    Power up Time Capsule airport

    Reset the AirPort Extreme back to default factory

    Set up AirPort Extreme still extend wireless signal of the time Capsule

    Can I create an Airport Extreme (current generation) network of roaming with a cable modem/router xfinity manufactured by Cisco (DPC3939 to be exact)?

    Yes, if the Airport Extreme will be connected to the Cisco DPC3939 back using wired Ethernet wired, permanent.

    The modem-router Cisco/Xfinity put into bridge mode?

    No. I you have done this, the Cisco/Xfinity device would only act as a simple modem... so it would not be a wireless service to all.

    A note of caution here... the support document you are referencing... Wi - Fi base stations: install and configure a roaming network (802.11 a/b/g/n)... use the examples that are long outdated does not follow with the versions present on a Mac AirPort Utility or iPhone/iPad.

    There are some good general information in the document.

  • Airport for Time Machine utility settings / Airport Extreme network

    I just added a new Airport Extreme to my former Network Time Capsule, to extend my Wi - Fi. I have read many posts and checked different websites, but I'm just getting more and more confused.

    My internet DSL cable is connected to the Airport Extreme and then 2 ethernet cables both time Capsule and my Imac G5. What would my network settings in Airport utility to the Airport Extreme and time for a better return Capsule?

    How can I find out if the two grow Wi - Fi?

    I just added a new Airport Extreme to my network of Time Capsule prior to extend my Wi - Fi

    I think we got it... and we understand. This tells us that you have added an AirPort Extreme to the core network to ensure the widest coverage Time Capsule wireless.

    My internet DSL cable is connected to the Airport Extreme and then 2 ethernet cables both time Capsule and my Imac G5.

    No, unfortunately, we do not have it.  This tells us that your AirPort Extreme is the main router and that you have added a time Capsule to provide wider coverage wireless for the AirPort Extreme network.

    Sorry, but we are confused. Which of your statements above is correct?

    AirPort Extreme extends to the Time Capsule network, or have you changed your network so that the Capsule extends the AirPort Extreme network?

    Could you please provide the serial number and the model of your DSL modem?

  • Airport Extreme cannot connect to 1000base t

    Description:

    Hi all.  My ISP is Cox Communications in the South of Louisiana.  I am currently subscribed to get 200 Mbps download speed.  I have an Arris Surfboard 6190 cable Modem.  Ethernet is connected to an Apple Airport Extreme 802.11ac, who then goes to my iMac (2011) as a high school Apple Airport Extreme 802.11ac (network extension).

    The problem.  Modem guard fall signal forcing me to reset the modem about 3 times / day.  Level 2 of Cox support said I need set the local IPv6.  This modification of the parameter stop the Modem from falling (in the process to test this now).

    2nd problem.  My iMac, nor either routers Apple will connect higher than 100base T.  I can see it in the utility network on the iMac.  The support of Cox who sees so.  However, when I connect the Airport Extreme directly to the Modem, Cox support can see that it is a Gigabit device, but after a few seconds, he is down to 100base T.  If I try to manually connect to 1000Base T on the iMac... it will not connect.

    Is there something that I am missing in my settings on the routers or the iMac?

    It is known of problems between all a single serial port SB modems and routers from the airport...

    There is no solution... or is defective, but they hate just each other.

    The best solution is the replacement of the modem or the router.

    We have been recommending the brand zoom but with Cox even modem that can not solve the problem... so I recommend a different router for now... a cheap... it will work quite low-end... TP-Link WR1043ND v2 or v3 for example... It is aprox $50 on Amazon. You can still use the airport bridge and work with Mac protocols for wireless AP.

    Normally, you could fill the AE to the new router, but you can give it a more active role... See the static IP address.

  • Airport Express is no longer connect to Airport Extreme

    OK, it's kinda a complicated question.  For starters, I will describe my current setup:

    Cable modem Motorola-> Airport Express #1-->(Ethernet over powerline)-> Airport Extreme-> multiple Airport Express for AirPlay

    Airport Extreme and Airport Express #1 are put in place to create wireless networks, with different names for 2.4 Ghz and 5 GHz frequencies.  I love this configuration because it allows me to play music simultaneously on the four different speakers hooked to my Airport Express units while offering good coverage in my apartment together.  It worked perfectly until two days ago when two of the Airport Express units lost their connection and are now flashing yellow.  I tried to restart the Airport Express and Airport Extreme, but nothing helped.  When I launch iStumbler, it looks like Airport Express #1 and Airport Extreme both create networks of right, but who is the Airport Extreme 802. 11A instead of 802.11n - don't know if it of a problem or not.  I suspect that the Airport Extreme is not working properly because when my wireless connection when you use my iPad near the Airport Extreme, that used to be solid as a rock, is now uneven intermittently.

    Any ideas on how I can solve this?  Thank you very much!

    It sounds like your extreme is the very old Gen1 or Gen2 model without dual band.

    Back to the factory and start over. It's the best way to solve problems... reboot is worth a trial, but in the end, you sometimes just have to redo the installation.

    I have a setup of the airport with two airports of previous generation connected in Bridge mode. (NOTE that this is not the same thing as a network via a wifi - connection Wi - Fi). I want to upgrade one of the units. I believe I read somewhere that the current model of (ME918LL/A) does not support bridge mode but can't find information about this in the specifications of the device.

    Bridge ME918LL/a mode?

    I believe I read somewhere that the current model of (ME918LL/A) does not support bridge mode but can't find information about this in the specifications of the device.

    Your feelings are what they are, but as any airport, Bridge Mode router is available as an option in router Mode for the 802.11ac current version of AirPort Extreme.

  • Airport Extreme loses the connection to the home network

    I have an Airport Extreme (AE) with Cox Internet in my house. Version AE 7.6.7 since the end of may 2016, I lost WiFi connection radomly. I had a Cox technician out who finished just change a 'filter' in our neighborhood who feed on other Cox at the reception. He said this analog filter had to be upgraded to a digital filter.  Despite this, my WiFi kept down again. According to other Threads of the community, this problem was solved by putting the IPV6 in AE parameter for "link-local only.  I did this and still it is falling.

    According to a recent post in support of Cox:

    Most of the routers to retail, especially those produced in recent years, are completely compatible with IPv6. Cox has determined that the Apple AirPort Extreme routers, including Time Capsule models, may know Internet connectivity issues when running the firmware released before May 25, 2016. For more information, contact Apple Support.

    To a Moderator: Apple will have an AE update for this problem?

    The moderators of the forum are not questions on a user to user support forum, so don't expect a response from an Apple employee.  Please contact Apple Support directly if you wish to speak directly with Apple.

    Then, Apple has already released the new firmware... 7.6.7 May 25... so it's not the question that you reference in the statement on the website of Cox. Cox was referring to a firmware sooner, like 7.6.4, for example in their declaration.

    We have seen a number of messages from other users of Cox, who reported that the new firmware has resolved connection issues that existed before.

    To find out where the real problem may lie, I suggest that you connect a computer (with the wireless turned off) directly to one of the LAN ports <>- on AirPort Extreme for a few days and keep an eye on the connection.

    Post back your results. Then, we'll know if you have a general Internet... connection problem that could be a problem of modem... or a single wireless issue.  In all cases, it will help if you provide the model number of the AirPort Extreme you have... and... he make and model number of the modem you are using at the moment.

  • The Airport Extreme WiFi intermittent 2nd generation

    I'm having a weird problem with loss of WiFi on my Apple Airport Extreme.

    My 2nd generation that apple Airport Extreme Base Station began to close its WiFi broad signal several times.  It happens usually after 60 minutes or less works very well.  Power on and the new runs for awhile until it stops again the WiFi.  Green light normally forward either static rest without flickering to indicate data transfer, or it will just dark.  Sometimes it will turn off WiFi and then restart WiFi a few minutes later and appear to be good.  But mostly it just stops and I can, he extinguished/turned on to operate correctly with the WiFi again.

    Airport Extreme is connected by ethernet cable to my modem/router main fiber (which is a different floor home) and it is set to "Bridge" Mode  It worked without any problems and I did no changes to my system.  My ISP did update my modem broadband fiber a few weeks ago to a "Virgin Media Hub 3.0"I understand was made by Compal.»  It seems to work perfectly and I have no problems with speed download or reliability in wireframe.  I was away from home for about a week and was able to access my wireless IP camera remotely via my Airport Extreme with no problems.  The problem started almost immediately on my return, but, as I said, I did no changes to my network.  I have never had this kind of problem before with my Airport Extreme.

    I am running OS X Yosemite on an iMac that is connected by a cable ethernet to the Airport Extreme and seems to work very well even when WiFi is de-energized on the Airport Extreme.  Airport utility reports the airport as current firmware version 7.6.7.

    I used network utility, Fing, and it showed that my Airport Extreme has multiple IP addresses, which seem to conflict with the IP address for my three AppleTV.  I manually changed the IP addresses of the Apple TV to another IP address not conflicting, but Fing always shows that my Airport Extreme has three IP addresses and I still have the problem of WiFi.

    Any other suggestions on a probable cause of this problem or the best way to solve the problem would be much appreciated.

    Thank you!

    The question is the 2nd generation AE is now too old.

    I would say the power supply (external or internal) is dying.

    It service life is approximately 5 years... your must be 8 years old. so the solution is simple... buy a new one... or I'll tell... Newish...

  • Airport Extreme network 4G connection

    I currently have the following configuration for my internet appliances:

    I have an Airport Extreme unit serving wireless three units Airport Express to extend WiFi coverage throughout the House. Physically connected to the Airport Extreme via ethernet are two televisions Panasonic who can access the same places predetermined via the internet (for example, BigPond movies and television, People, ABC iView, SBS OnDemand). To enable connectivity to other sites such as Netflix, Stan etc every Panasonic TV has its own unit of Apple TV connected to Airport Extreme via WiFi.

    I use Airport Extreme for all my other internal needs such as web connectivity MacBook and iPhone.

    The Airport Extreme WAN port is so physically connected to the ADSL modem and line phone Telstra for the Exchange, which is about 4 km.

    The problem is that the speed of download of the ADSL 2 + are poor, maxing out at about 3.5mbps. When I listen to the live broadcast of MotoGP and World Superbike racing the picture often freezes while he puts in buffer. Watched movies via Netflix and Stan often freezes too.

    I just ran a speed test on the Telstra Mobile 4 G network and I got a download speed of 111.94Mbps 41.77Mbps upload speed.

    Now, I'm thinking it would be great if I could connect my home network to the internet via their WiFi 4 G device X Pro Advanced.

    My question is this:

    Is it possible to connect the Airport Extreme to the Telstra WiFi 4 G device and the use of the mobile network for my internet and get rid of the ADSL modem? I don't think I can use USB Extreme airport connection, I think that the port is only to connect a printer, but I do not know if the Airport Extreme talk wireless Telstra 4 G device. Documentation of Telstra said their device will connect up to 10 devices using WiFi, but I do not know if there would be problems with the Airport Extreme router to talk to her.

    After spending heaps on all these units of Apple (1 x Airport Extreme) and 3 x Airport Express I don't want to lose, but if there is no way to Airport Extreme wireless unit of Telstra (or if this method is ridiculous) so maybe I might be able to get the device of Telstra to talk to all my other WiFi devices directly. Then, I might be able to sell the extreme and expresses it.

    I had a discussion with Apple Support through their chat session, but the person with which I spoke was not able to help.

    Thanks in advance.

    You need a device that is able to connect via Ethernet to the AirPort Extreme base station.

    With a plain/direct USB 4 G modem, a router broadband mobile sometimes can act in Bridge mode and thus provide a conversion method. For example, Dovado has these routers, but their modem (http://www.dovado.com/en/support/modems) compatibility list appears to cite that a single Telstra USB 4 G modem (ZTE) which supports the mode bridge.

    Your question indicates, however, that the 4G modem is actually a mobile access point (providing a local Wi - Fi network). If so, it may or may not be possible to use the wireless Ethernet Bridge (maybe even a model of Apple AirPort Express appropriate) to join this hotspot wireless and then connect via Ethernet to the entrance of the AirPort Extreme. This is all experimental, however. Various problems, including double NAT, are to be expected.

  • 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.
