• AirPort Extreme, gigabit Ethernet switch and covering my house

  I have an AirPort Extreme 802.11n to Time Capsule wireless router. I have an old House. It was built in 1852 and microwave ovens have a hard time penetrating through some walls.

  Recently, I made some changes in the House and I wired things for Gigabit Ethernet. I have not yet bought a switch. We have a Mac Pro (cheese grater), a Mac Mini, three iPhones (only 6) and two iPads (one version 3 and the other, only the latter bought autumn, an iPad Air.)

  First of all, since most of us are on 802.11 n, can I initially put in place a heterogeneous system with two routers wireless connected to themselves and to the Internet via a switch? Also, I need two switches; one for the internal LAN and the other for a connection to the Internet? I intend to buy the new ac 802.11 AirPort extreme for a facility in one of the rooms to better cover the rest of the House. I think that both devices will be able to take advantage of the signal of 5 GHz, initially, with another iPad and iPhone to come along the next year. I wouldn't or the other base station being "enslaved" to the other but, rather, connected to the wired network internal and devices just switch between them that move around the House.

  Comments are welcome here. This can be a trip to a Genius Bar if I do not hear from final here.

  can I initially put in place a heterogeneous system with two routers wireless connected to themselves and to the Internet via a switch?

  Possibly, depending on the type of modem you have. See below info in this post.

  Also, I need two switches; one for the internal LAN and the other for a connection to the Internet?

  NO.

  I wouldn't or the other base station being "enslaved" to the other but, rather, connected to the wired network internal and devices just switch between them that move around the House.

  Not sure what you mean here. The two extremes of the airport will be connected to the cable network, so they will be in communication with them at all times. If you want to peripheral switch between them that move around the House... then you will need what is called a "mobile network"... so the two airports will produce a wireless signal that uses the same wireless network name. Apple Setup Assistant will put things this way by default.

  Depending on the type of "modem" you have, the network might look like this:

  Internet > Modem > AirPort Extreme 802.11ac > Ethernet switch > AirPort Extreme

  or, if your "modem" is really a modem/router, also known as, a walkway... then you have the ability to set things up like this:

  Internet > Modem/Router > Switch > the two airports to connect to the Ethernet network

  Looking for a Gigabit Ethernet switch to your network. Switches come in 5 ports, 16 channels, 8 ports, etc. versions.  It's always a good idea to buy an Ethernet switch over a few ports that you think that you may need right now... to allow for expansion.

  The key here is that the type of modem you have will determine how to configure the network.  If you could provide the number of brand and model of your "modem", we can eliminate some of the assumptions to be used at this time.

• How to use Airport Extreme with ethernet leased line

  Hello friends,

  I was wondering if Airport Extreme is a true router, can I connect gout ethernet of my leased line directly in its WAN port, rather than put the provided ISP router between the two? I have lived many positions and all seem to suggest the connection of a cable/dsl modem to the WAN port on the extreme. Not found any information where it shows the ethernet line rented directly linking in the Giga WAN port, without any 2nd device in the meantime.

  If it's possible, then I guess also what public IP provided PSI can be put into the WAN of AE interface. Can someone develop more on it and detail the steps of configuration? Given that EI has basic firewall NAT, I think it's doable, but can someone confirm please.

  Thank you very much.

  Temporarily, if you connect your computer directly to the Ethernet line, can you get a good connection Internet in this way?

  If so, then AIrPort Extreme could function as a router for you, but you are also likely to face a Double NAT error on the network. How well... or, even if... This might work cannot be known until try you it.

  If the computer cannot connect, then what is required of your supplier for the computer to connect and get Internet access?

• problem w / Airport Extreme base station and modem Netgear broadband

  I just changed to ATT Uverse to Time Warner - internet only.  With Uverse, I was using my Airport Extreme base station to create a wireless network, and it has worked well in this capacity.  When you switch to TWC, the tech got the modem (TWC allows you to buy your own modem, so I bought a Netgear CM600 a recommended model) enabled and works very well, but could not get the Airport base station to talk about her (yellow light blink on the base station).  So, he opted for a TWC wireless modem/router.  Interestingly, I found that I could plug the Airport base station in the TWC modem (without any reconfiguration, just plugged into the WAN port base station to the modem ethernet port, as I had had with Uverse equipment) and voila!  It worked immediately.

  So, I called TWC to retry my Netgear modem.  I have the base station power off, plugged on the ethenet port Netgear, put back under tension and just got the blinking light.  I know that the modem does not work, because my iMac's network to the internet through the base station, for the Netgear, and go outside and I can fine surf in this way.  So it is something in the wireless configuration that must be different between the TWC modem and the Netgear modem.

  Obviously, I'm not an expert at this, basic troubleshooting tips would be appreciated.  The base station functions as a router (I can connect through a port ethernet through it), it is simply not generate a WiFi network for me...

  Thanks for the tips

  So, he opted for a TWC wireless modem/router.  Interestingly, I found that I could plug the Airport base station in the TWC modem (without any reconfiguration, just plugged into the WAN port base station to the modem ethernet port, as I had had with Uverse equipment) and voila!  It worked immediately.

  If your AirPort Extreme has been in its original configuration, it would act as a wireless Internet router. If you connect another router upstream to the extreme, there is work, but you'll have a condition known as: Double NAT. This isn't necessarily bad, but should be avoided if possible. To do this is simply to reconfigure the downstream router (in this case, the extreme) under a bridge. This disable its functions of routing and remove the error condition.

  However, if your extreme base station has been reconfigured as a bridge, if connect you directly to a simple modem, like the Netgear CM600, then this configuration will not work because no device will provide the necessary routing functions.

  It's always a good idea to perform a full power recycle your network hardware during change of equipment. Maybe that's the only thing your missed when you design your own? If you haven't done so already, please give it a try with the CM600 & Extreme combo. After return your results.

• Airport Time Capsule ethernet and WiFi installation

  I am trying to set up my home network, but also, somehow, the practice run for the configuration of my future business...

  Here is the component.

  -Modem: Fast 5250 BELL FIBE Home Hub 2000.

  -Airport Time Capsule 1 t (a big)

  -AirPort Extreme (large)

  -AirPort Express (size of the Apple TV)

  Here are the different coverage area and device usually used in the:

  -office: Printer via USB or ethernet, ethernet MacPro, 2xMacBookAir.

  -Living room: Smart TV, Apple TV2, PS4 (all via ethernet if possible) as well as a bunch of iOS devices and laptop computer via a Wi - Fi connection

  -In room: IOS, Apple TV via Wi - Fi device.

  So good, here's the catch, the modem's in the entry closet surrounded by concrete, so I close the Wi - Fi on it. Cable Ethernet running from there, at the office, upstairs room and the main living area. The plan was to put the TimeCapsule 1 t in the office, extreme in the living room and express on the floor. But I already have problems that they can't be all connect via Ethernet in the modem... Oh! What a mess, he made... So I saw on the support page from apple, is it better to put the airport Time capsule 1 t as principal to create the network. So if I put the Capsule in the closet as the main will be backup my stuff via ethernet?

  Also, I have the older version of Time Capsule (dish 500 GB). Shud I use it as the main airport will be connected to it via ethernet anyway?

  And finally, I connect to the modem using PPPoE bell hand and another airport the main via Bridge DHCP mode. Is this fair?

  Probably all covered already in other posts sorry if it is redundant. Thanks in advance for taking the time to help me.

• EqualLogic SAN and Jumbo frames

  I can't get the jumbo frames to work on our Equallogic PS6000.  We have the following configuration PS6000-> Dell PowerConnect 6248 (bunk)-> Windows 2008 Server.

  The network cards on the SAN has been set at 9000 MTU, ports on switches are set to MTU 9216 and the NIC on Server 2008 is fixed to 9014 with active RX & Tx flow control.

  When the server connects to the SAN, newspapers account connection iSCSI target to the initiator "172.21.X.X:3260, iqn.2001-05.com.equallogic:0-8a0906-xxxxxxxxxxx-23a001a955452af6-server1" ' 172.21.X.X:49156, iqn.1991 - 05.com.microsoft:server1' managed, using the length of the standard framework.

  When I ping the SAN of Server 2008 with a shitload of 8972 bytes, it works very well.

  C:\Users\system>ping 172.21.x.x f-l 8972
  Ping 172.21.x.x with 8972 bytes of data: reply from 172.21.x.x: bytes = 8972 times<1ms ttl="255" reply="" from="" 172.21.x.x:="" bytes="8972"><1ms ttl="255" reply="" from="" 172.21.x.x:="" bytes="8972"><1ms ttl="255" reply="" from="" 172.21.x.x:="" bytes="8972"><1ms ttl="">

  Why 8972?  Told that some genius on the internet.  Any help would be greatly appreciated.

  Well we got it to work.  On Server 2008, we have Broadcom and Intel network adapters.  For our tests, we were just using the Broadcom NIC.  Properties Advanced NETWORK adapter, we initially have the value package Jumbo 9014 and it did not work.  So, we opened the Broadcom Advanced Control Suite that came with the NIC and searched and found that there are two parameters that need to be addressed.  There is a jumbo packet definition which has been set at 9014, which is what we wanted it in the advanced NIC Properties.  There is another parameter, MTU, which can be seen on the advanced NIC Properties.  It has been set at 1500.  Once we define to 9000, frames jumbo started working.  We then uncabled Broadcom NIC and wired the card NETWORK Intel and the value of frames 9014 on advanced network adapter properties.  Once we have that frame has worked on this NETWORK adapter, no other measures were needed.  If it's working now.  Thanks to everyone for their help.

• question of vMotion iSCSI and jumbo frames

  Hello

  I have a cluster ESXi 4.1 using vCenter and a SAN MD3200i.  I'll do an upgrade to optimize the installation, which includes the installation of four NIC ports in hosts that will be used for iSCSI.  I struggle to enable frames or not, but if I do, I just want to do for the iSCSI, at least for now.  Currently, the maps iSCSI network on the hosts and the MD3200 iSCSI connections are connected to two switches separated, although I have seven other switches in the building connected to the PC, printers, etc.  What I only turn frames on two switches that iSCSI is connected, or do I have to enable frames on all my switches?  There is a Dell 2724 and eight 6224Ps of Dell.  ISCSI is connected to the 2724 and one from the 6224Ps.

  The two switches that are connected to the iSCSI ports are not dedicated iSCSI switches; they have other devices on them, but I can only enable the frames extended globally on the switch.  Would there be any problem allowing the frames extended on the switches, otherwise all connected devices are configured for them?

  Another question about vMotion: I will create four ports on each host for iSCSI vmkernel.  Currently, there is also a port configuration vmkernel for traffic management and vMotion.  Is it possible to set up each of the four iSCSI for vMotion vmkernel channels, or should I leave it configured on the port of vmkernel management?

  Thank you!

  Sure. If you're going to enable Jumbo frames, you need to have dedicated switches for that, or a switch that may have different units MTU on their ports.

• ESXi 5 and Jumbo frames

  What is the proper way to configure some jumbo frames for an ESXi cluster used shared storage NetApp?  Configure extended frames to the bottom of the VM Guest NETWORK card or I stop at the dvSwitch?  I already configure jumbo images throughout the storage on the physical hardware.  It's just the virtual machine where I'm not sure and if I do not set up the virtual machine, will there be problems?

  Thank you!!

  Then, you don't need to do anything for the virtual machines.

• vMotion and Jumbo frames

  Enabling Jumbo frames ever advantage vMotion traffic bad? We will migrate out of our HP EVA on Netapp Storage soon. Currently, we are a single Fibre Channel shop now, but consider using NFS on Netapp only to align virtual machines (recommendation of Netapp Professional Services to increase the speed of the mbralign of a Linux VM).

  As we will only use really based on IP storage for the storage of virtual machine production, someone suggests to go even bother to change the size of the MTU on our switches and virtual switches?

  We are currently using 4.0U1 ESX and vCenter 4.0U1 but will be upgrading to 4.1 ASAP.

  I have never heard or read something about enabling Jumbo frames for vMotion. I don't think it's even a supported configuration.

  There are docs on activation of traffic iSCSI Jumbo frames. Most say, there is no advantage to 1 GBit networks but a significant advantage for 10 Gbps networks.

• TSO and jumbo frames

  Hi guys

  Question: to enable frames and TSO.

  Needs active on ESX Jumbo frames, but not OSI?

  The two needs enhanced VMXnet adapter in VM and much-needed replacement NIC so it wasn't EV adapter?

  no support for iSCSI on frames?

  Also only windows 2003 entperprise (in the range of windows server familty products) supports these features?

  Thanks in advance

  See you soon

  The enhanced vmxnet (or vmxnet2) is avaible in ESX 3.5 and 4.0.

  The vmxnet3 only in 4.0

  Hello everyone.

  Happy new year.

  Please can someone answer my question.

  Extended frames are not supported in the free ESXi 4.0 edition

  This is discussed here.

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1012454

  Are they supported in ESXi 4.1 Free Edition or should I upgrade to Essentials?

  Thank you very much

  James

  Extended frames are supported in ESXi 4.1. http://KB.VMware.com/kb/1023990 just not in the free version, at least through the vCLI.

• Jumbo frames based on VI3 3.5 / iSCSI initiator of material?

  Hello

  Apologies if this has already been posted. If so please point me to the thread, but I just wanted to confirm with you guys jumbo frames based on VI3 3.5.

  As much as I know frames are not taken in charge for software iSCSI but it is supported for the hardware iSCSI initiators but please correct me if I'm wrong. Now what hardware initiator you recommend for jumbo frames?

  Thanking you in advance,

  Saludos,

  In ESX 3.5, 10 gigabit Ethernet and jumbo frame are NOT supported on storage traffic (for example, the software initiator).

  In ESX 4 are supported.

• Gigabit Ethernet through AirPort Extreme

  I just got a gigabit home connection. If I connect my iMac via ethernet to gigabit municipal internet provider modem, II can get about 800 Mbps download based on the file netspeed.com. Nice.

  However, when I use my Airport Extreme as a router ethernet (put the extreme between the iMac and the modem) my speed drops to about 1/10 of that.

  None of the devices that I currently own are capable of handling 802.11 ac, so I know I could not anywhere near gigabit wireless speeds. But it would be nice to have the fastest speeds on the one machine I intend to connect via ethernet, then connecy to the extreme wireless.

  Airport Extreme really limit the ethernet so? Is there a setting I can adjust for more fast ethernet routing?

  If the AirPort Extreme 802.11ac is configured as a DHCP and NAT router, then the WAN to LAN speed will be limited to about 300-400 Mbps.  Check the results here:

  http://www.SmallNetBuilder.com/tools/charts/router/view

  If the AirPort Extreme is configured in Bridge Mode, then you would expect to see 600 - 700 MB/s speed this way.

  http://www.SmallNetBuilder.com/tools/charts/router/bar/75-LAN-to-Wan

  If you don't see results, then the AirPort Extreme is not to negotiate properly with your modem speeds.  Unfortunately, Apple has removed all the settings to manually adjust WAN port on the AirPort Extreme 802.11ac speed, so there is not much you can do others try a few unusual things...

  One of them would be to insert a Gigabit Ethernet switch between modem and AirPort Extreme to see if it will negotiate better speeds like that

  Another would be to try an Ethernet cable between the modem and AirPort Extreme cross.

  If none of these things help, then you should ask Apple to replace the AirPort Extreme to you and hope for more luck in the next test.

• Can I connect a wireless modem to my Airport Extreme base station via ethernet and then connect this Ethernet modem to my TV to pinterest?

  Hello

  I want to connect my TV to my Airport Extreme via ethernet, so I can run Netflix. Can I just the branch? Can or, if it does not reach, I use an old router as a bridge linking to the Airport via an ethernet cable and connect the router to the TV?

  Thank you

  Lisa

  I want to connect my TV to my Airport Extreme via ethernet, so I can run Netflix. Can I just the branch?

  Yes.

  Can or, if it does not reach, I use an old router as a bridge linking to the Airport via an ethernet cable and connect the router to the TV?

  Yes. It is also possible, but only by using an Ethernet switch instead of a router would be a better solution. The important thing is the total distance of Ethernet between the extreme and the TV. Ethernet is limited to 100 m (328 ft)

• 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.
