Do my Airport Express just buy are with 802.11n?

I using imac 2.4 GHz model 2008 which understand that it build in with airport extream 802.11n standard, isn't it?
Also just buy Airport express but doubt that this AX is on which 802.11n or not?
Because it shown only 802.11 a/b/g.
And since I found software for airport 802.11n available for 1.99 US$, Do I need to install this software to be able to run 802.11n?
Thank in advance.

No, special software isn't needed. You have AirPort Utility already installed on your iMac and it is located under Applications/Utilities. Run AirPort Utility and go to Wireless and make sure you have an 802.11n mode selected (whether it is 802.11n only or 802.11n with b/g compatibility enabled).

802.11n Extreme + Airport Express on same WDS w/802.11n speed?

I'm traveling now, but when I get home on Monday morning a factory refurb Core2Duo Macbook Pro waiting for me. I've had an Airport Extreme 802.11n for a couple months now and would love to upgrade the network for 802.11n (for faster transfer speeds to the Airdisk I use as the depository for all my music). but I have an Airport Express I want to keep on the same network (in order to stream internet radio to my stereo since that feature was conveniently left out of the Apple TV, though the Express also serves as a bridge for my Xbox 360 & PS3). Is there a way to configure a WDS so I can keep the Express in the loop and enjoy 802.11n speeds? I read the Apple support doc, and it was kinda vague about whether it would work if I followed the model that involves running an Ethernet cable from the Extreme to the Express? I'd hoped the manual would clear things up, but it only left me more confused...

I have a similar issue here, only I'm keeping my snow Airport base station around just in case. I assume the following will work:
Airport Extreme 802.11n
-connects via ethernet cable to-
Airport Snow
-which connects wirelessly to-
Airport Express.
The Snow has a spare ethernet out, which can connect to a PS3, Network Area Storage Hard Drive, or a TiVo at 802.11n (or higher, since it's all wired) speeds.
The Airport Express has AirTunes out of the mini jack.
My only question is this: does having the Airport Express connected to the Airport Snow (via 802.11g, I assume) put a drag on the overall 802.11n speeds? Or because the Snow and the Express are only on "bridge" setting, it's a non-issue?

AirPort Express doesn't work with SB5100

I'm helping a friend set up a new AirPort Express MC414LL/A Model A1392 (802.11n) with her existing Motorola SB5100 DOCSIS 2.0 cable modem. I was able to setup the AirPort Express from her iPad with a network name and password. Also upgraded the firmware in the AirPort Express. However, the Airport Utility App on my iPad and iPhone connected to the AiPort Express, but showed no connection to the Internet. Furthermore, the PC that had been working fine when connected directly to the SB5100 could not make an Internet connection when connected to the AirPort Express.
I brought the AirPort Express home and connected it to my Verizon FiOS Actiontec modem and it works fine - my iPhone and iPad connect to it and through it to the Internet.
I'm wondering if the SB5100 is incompatible with the AirPort Express??

It should work.
Power down the modem and leave it powered down for a long time, as much as a half hour or longer is sometimes required. While it is powered down, disconnect its coaxial cable. Literally unscrew it and leave it that way.
Connect the Express to your modem, leave them connected, and do not disconnect them from one another without powering down the modem again.
Re-connect everything including power and let the devices complete their startup sequences. This usually takes a moment or two.
If that does not result in success, "hard reset" the Extreme or Express according to the instructions below and start over from the beginning.
If you still have trouble, contact AppleCare because you have done everything reasonable to get it to work.
To "hard reset" an AirPort Base Station: make sure it's powered up, then press and hold its tiny reset button and keep it depressed for five to ten seconds, long enough for its LED to flash amber rapidly. Release the reset button. Then, the LED will glow amber steadily for about a minute. Then, it will flash amber, slowly, about once every second or two, waiting for you to configure it with AirPort Utility.

I have bought a new airport express and using it with my macbook (iTunes 10.2.2). I have joined an existing network for internet in my home and with that i am trying to play the music via itunes but there is audio dropouts every 60 secs or so. any soln ?

I have bought a new airport express and using it with my macbook (iTunes 10.2.2). I have joined an existing wireless network for internet in my home and with that i am trying to play the music via itunes but there is audio dropouts every 60 secs or so. I am using a set of speakers from kenwood connected to the airport express. The operating system on my macbook is mac os X 10.5.8. i am sure it is not a problem of streaming music online because i have even tried playing music which are stored in my macbook.
Is there any problem with the setting in itunes or quicktime ? Kindly reply...... I am waiting for your valuable suggestion.
Thank you a lot in advance.

I am shocked to have found this same AX audio dropout problem starting TODAY, every few seconds the audio just drops for a couple seconds and then resumes: Latest software versions of everything. No iPad, iPhone or Touch. Internet hardwired to D-Link DES1105 (1000baseT Switch) hardwired to new 80211N AX, AX optical to stereo, AX Wi-Fi internet to basic 1st-gen MacBook operating at 80211G, and an older 'G' AX extender at the far end of the house, away from all this. The MacBook streaming iTunes is usually 12 feet from AX. I've used this setup for years of trouble-free AirTunes / Airplay until today. Today I also found 2 very reliable fixes and 1 way to force a dropout, but first, I read some posts and tried ALL following settings one-at-a-time and restored them ALL because NONE of them helped: Turned off IPV6. Streamed to multiple speakers 'Computer' and 'AX' (restored to just AX). Turned off 'Ask to Join new (WiFi) Networks'. Turned off Bluetooth (can't live without Magic Trackpad, so glad that wasn't it). Here's my discoveries: Lo and behold, each time I click the Airport icon in the Menu (you know it shows you've got 4 bars from AX) when the status switches to 'Looking for Networks' for a second it CAUSES the AX audio to drop out for a couple seconds (it never did that before today.) iTunes still playing, streaming, AX laser still lit, but the 'PCM' light on stereo and the sound GOES OUT EVERY time I click the Airport icon in the menubar, just like the regular, annoying dropouts. So, to reduce traffic I quit Safari (3 tabs, no streaming, just Gmail, Google, and Netflix browsing). Lo and behold, the dropouts stopped altogether. No other Web apps going (not iTunes Store, Genius, Ping, nothing), so I launched Chrome to the same 3 tabs and the dropouts HAVE NOT RETURNED. That's right, not only did simply QUITTING SAFARI cure it, and Chrome doesn't contribute to it, but I can demonstrate it just by forcing my Airport to re-scan. Works for me, written using Chrome. The other reliable fix is to hardwire MacBook to the Switch. This is obviously not ideal, but Airplay audio doesn't drop out over Ethernet. Also, in all my tests, it made no difference whether iTunes did the streaming, or Airfoil did.

Hi, The Airport Express does not work with iOS 7.0.4, I appreciate your help to resolve this event. Thank you,

Hi, The Airport Express does not work with iOS 7.0.4, I appreciate your help to resolve this event. Thank you,

Please locate the model number of the AirPort Express and post back that information.
The model number is located on the side of the AirPort Express. It begins with an "A" followed by four numbers.
We are not sure what you mean by "does not work". Does this mean that the AirPort Express worked at one time and has just recently stopped working?
Have you installed a newer operating system on your iOS device recently?
Or, is this a new AirPort Express that you are trying to configure for the first time?
If yes, what service will the AirPort Express perform on your network?
Please remember that we cannot see your network, so we only know as much about your problem as you can tell us.

The audio on my Airport Express just died

The internet connection works fine. It's the audio output from iTunes to my home stereo that appears to be cooked. It's set up the way it always has been.. 1/8" connector into the Tape1 RCA jacks. The CD player plugged into the amp works fine. Audio at the iMac is fine. I get the "connecting to Airport" message when playing tunes. Then audio starts to come out, but it is gargled and barely audible. Futzing with the stereo's input dial makes no difference.
I've reset the airport express three times. Always comes right back up (for the internet). Audio continues to be dead. I've tried inplugging and plugging back in the audio. I get a loud hum for an instant (normal.. it's the ground breaking contact and restablishing). But still, only the gargled weak audio signal.
I'm thinking my airport express just died. Any insights guys?

Hello katsu 2. Welcome to the Apple Discussions!
Do the Express stations expire after a certain time, and if so, would it have deleted my network info?
Like any piece of electronic hardware, the AirPort Express can malfunction and it is possible, based on your description, that yours has. If it isn't powering on, then most likely it will not broadcast a wireless network and why you are not seeing it from your computer.
One thing you can try, is to perform a "factory default" reset to see if this helps. You may have to perform it a few times just to be sure. If after doing so, if you are still not getting any status light indications, and the unit feels cool to the touch after being plugged in for 10-15 minutes, then there is a good chance that it's power circuitry has failed.

Airport Express just stopped working

I have been using the airport express fine just until few days ago.
I've being it using it with an ethernet cable connecting it fron my linksys router. (had it in bridge mode)
Everything was fine until few days ago, when the "airport express" just disappeared from my wireless signal choices.
I had to reset everything and it was working again for a few days and same thing happened again. it just disappeared and my green light on my express turned amber.
I've reset it a few more times after that but after maybe 10 minutes of it working, it will disappear again and turn into an amber light....
now i can't even find airport express on airport utility..
please help!

I'm also having the same problem with my macbook pro. I also have 3 other pcs hooked up. I was wondering if maybe it is my router or do you think its something with the computer?

Apple AirPort Express Base Station with 802.11n - MB321LL/A. How to set it up to my new iMac

Community:
How do you set up an
Apple AirPort Express Base Station with 802.11n - MB321LL/A how do you set up on Mac running on OS X 10.9.4?
Please advise
Fmsalazar

Apple did say it was important.
If the units do not show up in the airport utility then you must set it correctly to link-local.
Steps for OS X Lion or Mountain Lion
This can happen if IPv6 has been disabled. To enable IPv6 for your network interface:
Choose Apple menu () > System Preferences, and then click Network.
If a lock icon appears in the lower-left corner, click it and enter your admin name and password to unlock the pane.
Click your network service (Wi-Fi or Ethernet) in the list, and then click Advanced.
Click the TCP/IP tab.
Choose Link-local only from the Configure IPv6 pop-up menu.
Click OK.
Click Apply.
AirPort base station not seen or "An unexpected error occurred" appears in AirPort Utility 6.3
Apple rep says the same.
Re: Unexpected error when connecting Airport Express A1264 to Airport Utility 6.3.1
I am searching as I saw it in a thread today where a person had issues. (No contribution from me in the thread but found that was the issue).
It is kind of a fail safe.. since auto can end up with any setting.. and it will depend on the setting of ipv6 in the Airport Router if it works properly in the computer.. setting it to the correct value is one step in sorting out problems when people get in a mess.

Airport Drives Me CRAZY! New 802.11n Network Slower Than Old 802.11g/b

I've been using Macs since 1988 and consider myself an advanced user. However, every time I setup a new Airport wireless network or re-configure an existing one, I feel like a helpless newbie trying to figure out how to open a folder on my desktop. No matter how many times I read the manual or the help files or these forums, I can never grasp what seems like it should be a simple path from A to B to C.
Anyway, here's my current situation: I've been successfully (I think) running a 6 year old AP Extreme Base Station [AE] (in my home office addition) and 2 Airport Expresses [AX] (one AX roughly 15 feet from the base station--through sheetrock, and the second AX roughly 30 feet from the first AX--through sheetrock and some wooden stairs. (so roughly 45 feet from AE to 2nd AX). It wasn't the speediest thing going but it did the trick with older Macs.
I recently bought a MacBook Pro which supports 802.11n. I most often use this laptop at the point in the house furthest away from the AE (Base Station) The AE (Base Station) is in my home office connected to my MacPro desktop (see #1 below). In addition, the family iMac is also in that room furthest from the AE. Using the new MacBook Pro with the old 802.11/g/b network turned out to be painfully slow. I was experiencing the same slow network connection my family has complained about for years with their older Macs and 802.11g/b.
I decided it was time to upgrade the whole network, if only to speed up my MacBook Pro connection. Bought new 802.11n Airport Extreme (MC340LL/A) and 2 new 802.11n Airport Expresses (MB321LL/A). Setup did not go smoothly. Again, my normally competent Mac persona was reduced to a babbling three-year-old. Had three different Apple techs on the phone trying to help me through it. Got different, contradictory instructions from the last two. Finally got all three units working, only to find that not only does my MacBook Pro seem even more sluggish than when connected to the old 802.11g/b network, but my wife tells me web pages are taking at least twice as long to load as with the old network.
As concisely as I can lay this out:
*1. Airport Extreme (Base Station)*
Connected via Ethernet from its WAN port to my Comcast cable modem. One Ethernet (LAN) port on that AE is then connected via Ethernet to my Netgear 8-port Ethernet switch. Ethernet from switch to Ethernet port 1 on my MacPro. (MacPro does NOT have an Airport card because I forgot to order one. Also I confirmed that this setup was functional by connecting to the AE wirelessly with my MacBook Pro showing the name I'd given the new network prior to adding the two AX's to the mix).
Some Airport Extreme settings of note (all accessed via "Manual Setup" button):

SETUP/GOALS:
With Airport Extreme (Base Station) as the starting point, have the two Airport Express units with the strongest, fastest signal possible, provide Internet access (and file sharing, iTunes speakers capability) to three Macs (one older iMac, one older PowerBook and my new MacBookPro). Again, I believe my new MacBook Pro is the only one with 802.11n support, so I don't expect the other Macs to take advantage of the speed boost offered by the three new 802.11n devices.
+Any and all help with this will be greatly appreciated. Thanks!+

{quote}With the AirPort Extreme, in the AirPort panel, Wireless tab, click on the button for "Wireless Network Options", check the box for "5 GHz Network Name", and enter a different network name. (That can be trivially different, such as the name of the main network suffixed with an underscore and the digit 5.) Once configured that way, connect your "N" gear to each network in turn to see if one is any better than the other. (If you're wondering what effect this would have, it allows segregating your "N" gear from the older gear to prevent the older gear from slowing down your network. However, distance and interference from things like walls may negate any advantage.){quote}
William: I was gone most of yesterday, but had a chance to implement your recommendations today. I added the 5 GHz network as you suggested, but in order to connect to that at all with my 802.n11 MacBokk Pro, I need to be within a few feet of the AE (base station). If I try to access that network even from the next room (well within reach of both the AE and the livingroom AX, I get one bar and "failure to connect" messages just trying to logon to that network.
However, I did some experimenting that (as of right now, anyway) resulted in much faster network access, not only from my MacBook, but also from the older iMac which is the furthest Mac from the AE. According to my wife, that iMac is "loading web pages faster than I've ever seen them!"
Here's what I did:
1. Moved all three units to places where it seemed they would have the least amount of interference with the clearest path from unit to unit, also raising the height of both AXs from about 2-3 feet from the floor to about 5-6 feet from the floor.
2. Changed one setting on the AE (base station): Wireless Tab > Wireless Network Options > Multicast Rate ---> Changed this from Low to High.
I have a feeling the location shifts made the real difference, but I will try changing the multicast rate back to "Low" just to see what happens.

Data and Voice separation with 802.11n

Hi there
I'm interessting in some design guides. I would deploy data in 2.4 GHz band and the voice in 5 GHz band. But aren't there problems with the 802.11n deployment, I thought that this works better in 5 GHz.
What recommendations would you make and did you have some issues with this design?
Thanks in advance.
Dominic

Hi Dominic,
You can find all kinds of documentation on Cisco's 802.11n homepage: http://www.cisco.com/en/US/netsol/ns767/networking_solutions_package.html
To answer your questions, there is no "problem" with running 802.11n in the 2.4GHz space, but there are limitations. You cannot use channel-bonding, which is the primary source of the added bandwidth that 802.11n offers. If you want to see 150Mbps data rates, you'll need to deploy it in a 5GHz implementation.
Another advantage to running in 5GHz is that you can isolate your 802.11n traffic from your 802.11b/g traffic on the 2.4GHz radio. This will prevent slowdown that can occur when legacy clients coexist with 802.11n clients.
So yes, you're correct to say that it does work better in 5GHz. The nice thing is that most 802.11n chips in laptops support this band.
That said, it would be best if voice and data can both exist in the 5GHz space. You can accomplish this by creating different SSIDs for your voice and data networks. There is nothing wrong with deploying both in 5GHz.
Let me know if you have anymore questions. Thanks!

Extending My network with three Airport Express or buy an Airport Extreme?

I live in a large three story house and currently have it wirelessly networked using two Airport Express' but my signal is very weak on the third floor and in other spots throughout the house.
Would it be possible to buy a third AE and extend the network that way or would I be better off buying a AEBS?
Any thoughts or suggestions would be greatly appreciated.
Thanks

It will really depend on the construction materials used in your house or any other forms of Wi-Fi interference that could prevent a clear wireless signal. Both routes, you suggested, will have it advantages and disadvantages.
Extending the existing network wirelessly using a WDS, effectively, cuts the throughput in half for each base station in the chain...so, in this case the second AirPort Express Base Station (AX) (acting as a WDS relay base station) would only get half that of the first AX (acting as the WDS main base station). In turn, the third AX (acting as the WDS remote base station) would receive half of the second's throughput. The good news is that you should have a strong signal across each of the AXs, just lower throughput the farther along in the chain.
The 802.11n AirPort Extreme Base Station (AEBSn) has a greater range than either the older 802.11g version or the AXs. You may find that it will provide enough to cover you entire house. In the off-chance that it doesn't, you can still use it to create a WDS between AEBSn and your current AXs.

Do my Airport Express just buy are with 802.11n?
