Airport Express - forcing 802.11n 5Ghz setup

I've just bought a Linksys WRT160NL 802.11n wireless router and and attempting to force the Airport Express to use 802.11n rather than g. When I configure the AE, I join the existing network. There seems to be no way that I can configure it to use n/5Ghz.
Any suggestions?

Welcome to the discussions!
From your post, it sounds like you might have an older "g" AirPort Express. Might that be the case? If so, it would not be able to join an "n" wireless network.
To confirm, open AirPort Utility and click on Manual Setup for the Express. Then click on the Wireless tab to display the settings page. Hold down the option key while you click on the Radio Mode selection box. If you do not see any "n" options, you have a "g" Airport Express.
Are you trying to "extend" the wireless network created by the Linksys? I'm afraid this won't work even if you do have an "n" Express because it will only "extend" a wireless network created by other compatible Apple base stations.

Airport Express Upgrade (802.11n - wireless n)?

Does anyone know if Apple plans to upgrade airport express from 802.11g to 802.11n? If so, when. I am not sure if I want to purchase the current version if I know a wireless "n" version is on the way.

Airport Express in 802.11n mode with an Xbox 360

I have an Airport Express (with software 7.5.2) and am having problems connecting my Xbox 360 in 802.11n mode. I have an Xbox 360 (one year old, not the new 360 S Console) and an Xbox Wireless N Networking Adapter (Model 1398).
I believe my Airport Express is working fine as I've been able to connect my MacBook and iPad 2 when I've run the Airport Express in any combination of modes -- 802.11g 2.4 or 5.0 GHz, 802.11b compatibility, etc.
I've also found that the Xbox will connect when I run the Airport Express in 802.11g mode, but it fails to connect in any n mode. I've tried several combinations including varying the security -- WPA2 or no security at all. Since the same Xbox and Apple hardware can connect when running in 802.11g mode, and I've got Apple devices talking to the AE in 802.11n mode, I'm suspecting the Xbox hardware.
I've looked through a few forum posts here, and most of them seemed to be older and referenced a bug in an older version of the AE software. At least one mentioned that the person had a defective Xbox wireless adapter, which I'm beginning to suspect.
I've even turned on syslog logging on the Airport Express and used my MacBook as the syslog server. Even though I've turned the Syslog level up to 7 (Debug) on the AE, I don't get any messages about Xbox connection attempts -- just successful connections from my iPad and MacBook.
Any advice is appreciated!
Thanks,
Dan

Hi. Thanks for the reply. It turns out that the router was not going into n mode because of the security I set on it. I finally figured this out and the AE did connect in n mode after all.
Well at least it's working now but I feel a little bad for posting when it was my fault!!
Cheers!

Airport Express, WPS, 802.11n and 7.5.2 firmware - can this work?!

Can't believe this hasn't happened to anyone else, but I can't find a relevant thread.
I have a Time Capsule and an Airport Express base station. The Time Capsule was configured as a WDS base station, and the Express as a WDS Relay. The Express is less than a year old, ie 802.11n.
Everything worked beautifully until firmware upgrade 7.5.2 which self-installed on the Time Capsule just as you would expect - except the relay stopped working.
I've tried everything I can imagine, but I can't get the two devices to communicate with each other any more (even with the new firmware on the Express). I have read somewhere on the Apple site that WDS "doesn't work" with 802.11n, but this doesn't fully explain how it did work with 802.11n up until the time of the firmware upgrade to put it mildly. And releasing a firmware "upgrade" that stops existing configurations working, without warning, is not really an Apple thing to do.
One thing I haven't tried is to revert to older firmware; do I really have to do that? Or is there something wrong here please, Apple? Or did I just imagine, for those 9 months, that the relay was working sweetly?!
Don't know if this is related, but Airport Utility almost consistently fails to see both devices if they are both switched on, but can only see one or the other. Is it possible that the Express has developed a fault?
Please help; I have an old house and I can't penetrate most of it without my WDS!!

Might this apply?

HT4259 trying to exchange an airport express router 802.11n Wi-Fi can you talk me trough this?

Can somebody help me exchange my existing router and set up my Airport Extreme 8012.11n Wi-Fi?

Coyotelou, I believe I can help you. First, assemble your new Airport Extreme the way it shows you in the manual, and then plug it into an electrical outlet near your modem. Also plug the modem's cable into the port on the back of AE (it's the port with the little sunburst symbol.)
Second, in the Apple Menu (the Apple symbol on the left side of your menu bar) open Software Update. You need to be online for this part. If it suggests an update for Airport Utility, get it now.
Third, go to your computer and open Applications > Utilities > Airport Utility. This will be the newest version if you've just downloaded it. Your computer will "pick up" the signal from your new router that you just plugged in, and it will start asking you questions. It will be pretty straigh-forward. Just answer the questions and away you go!
Good luck.

802.11n (5Ghz) / UK / Performance

Hi,
I have an Airport Extreme upstairs and 2 x Airport Expresses downstairs (one is extending the network, the other is an ethernet bridge).
When I try and setup the extreme as 802.11n (5GHz only) I get dreadful coverage to downstairs (my MacBook and Expresses can't see it at all). I can connect in the same room via my MacBook but that's about it. With b/g compatibility all is fine again but I really want to boost my internet speed to the lounge where the expresses reside (by boosting the household wireless overall).
I saw old posts about changing country so you can use wide channels etc ... and I've tried some other country settings but the same problem with coverage. Is this a UK restriction - the lack of wide channels means a lack of coverage / performance under 802.11n only?
Thanks in advance for any advice ...

Higher frequency 5 GHz signals are absorbed by any obstructions, walls, etc much more quickly than 2.4 GHz signals. You really almost need line-of-sight between the computer and AirPort Extreme because the 5 GHz signals have much less penetration and distance power.

802.11n (5Ghz only) network and Remote App.

I have a Time Capsule set up 802.11n (5Ghz only). iMac, MacBook & New Airport Express all connected to its network. Transmit rate is 270.
My question is, if my iPod Touch is g rated only, then how can the Remote App control my Airtunes if it cannot connect to my N network. Because it is.

My Time Capsule
Wireless Mode=Create a wireless network
Radio Mode=802.11n only (5GHz)
My Time Capsule is connected to my Netgear (g only) router via ethernet.
I have the router broadcasting a g network for my iPod Touch. The Macs & AAE or all connected wirelessly to my Time Capsule N-only Network.
So the Touch should not be able to connect to my Airport Express as I understand it.

802.11n 5ghz Connection Problem with OS X 10.4.11 Tiger

I've searched the communities for answer to this vexing issue to no avail, so I am trying a post.
Situation:
I have a dual-band 1TB TC at home set up with three networks: 802.11g/b/a, 802.11n ((5ghz), and Guest Network (g/b). There are four Macs accessing it: (2) mid-2009 15" MacBook Pros, 2009 MacBook Air, mid-2006 24" iMac. All are running Snow Leopard 10.6.7 except the 24" iMac (Core 2 Duo) running 10.4.11.
All Macs can connect to to all networks EXCEPT the iMac which has a problem with the 802.11n (5ghz) connection ONLY. The iMac has the n-enabler installed (can see it registered when looking at Network Utility). In fact, the iMac will connect but any attempt to access to the Internet or TC disk stalls the system. Switch back to 802.11g and everything is fine.
I've looked at the Console for guidance but cannot find anything problematic (to my eyes, anyway). I booted this iMac to Snow Leopard from an external disk and the problem cannot be duplicated, so I am assuming this is not a hardware issue with the iMac. I also, did a fresh install of Tiger and updated it to 10.4.11 plus all Airport updates and n-ebabler on an external drive, booted from this drive and have the same issue with the 5 ghz n-connection.
By the way, when connected to 802.11n (5ghz) network with the iMac, I have full bars on the menubar fan, but then one bar drops after a minute or so. When this happens, I cannot access the Internet nor the TC disk.
I've tried various tweaks as described in the many, many discussion threads here: resets, establish new locations, clear/repair the keychain, and many others.
I did not have this problem in the past with this iMac, so don't know what has changed with the system configuration. The g-connection is rock-solid, so Internet access is fine, but file transfer speeds ober the network are obviously much slower now than with the 5ghz n-connection.
Anyone have any ideas? Without suggesting an upgrade to 10.6...clearly that should do the trick. I have other reasons for running Tiger on the iMac.
Thanks.

I wonder if all the activity was too much for the hard drive and it failed....you might contact Apple about this repair extension program to see if you qualify...

AEBS 802.11n 5GHz gives "invalid password" - need a solution!

After an update to 7.2.1 I've been trying for the past 4 hours to get back on my 5GHz network, but no success. I hope someone can resolve this, because it's getting extremely annoying.
- 802.11n (b/g compatible) 2.4GHz, pass or no pass -> works
- 802.11n only 2.4GHz, pass or no pass -> works
- 802.11n 5GHz, no password -> works
- 802.11n 5GHz, WPA2 Personal pass -> invalid password
I tried everyting. First setting it to b/g compatible at 2.4GHz (when it works in Leopard), then to 5GHz -> invalid password. Added it to my preferred networks, hard reset of the AEBS, downgrade to 7.1.1 and a hard reset, new names for the networks, different passwords, deleted everything from the keychain to avoid any mixups, countless reboots...
No results. I just cannot connect to a 5GHz network, because Leopard claims the password is invalid.
I have no clue what to do next. It worked fine until I upgraded to 7.2.1, and now even when I downgraded to 7.1.1, it still won't work. And 5GHz works fine without a password. But as soon as you set a WPA2 Personal (this or WPA2 Enterprise, which I don't want), Leopard says invalid password.
I also noticed that when I setup a preferred network in Leopard, and insert a WPA2 Personal password, it changes it to simple WPA, without the 2, when I save it. Although this is strange, it shouldn't matter. Because when I setup a 802.11n 2.4GHz instead of 5GHz network with a WPA2 Personal password, it works great with my WPA(no 2)-preferred-network settings.
I'm completely lost here. Who can help me out?
(Just a tip: do not, I repeat, do not ! update to 7.2.1).

Hi guys. "Good" to know we're not the only ones. I reported it also, let's hope an update follows soon.
I still don't know where the problem lies exactly. Mainly because it did work for me in Leopard, after I did a completely clean install last friday. It just picked up the network and it worked. I tried 7.0, 7.1, 7.1.1 and 7.2.1 about 5 times each now. All along with complete hard resets, powerdowns and all the possible settings I could think of, nothing works. First I'd say it's probably the AE firmware, but since nothing works anymore, I'm leaning towards Leopard now...
Maybe the password isn't being sent correctly to the AE, or the respons of the AE doesn't get received properly. There already was a Keychain update right after the release, maybe there are still more updates in that area, and they'll be included with the next big update.
If anyone finds a way to fix it, let us know! I'll keep trying, although I don't think it'll do much good

802.11n 5GHz no longer works on one Macbook

Good evening,
Our household has two Macs connected to an Airport Extreme 802.11n (July 2007), both are MacBooks (Late 2006). For well over a year, both have happily connected to the AE using 802.11n 5GHz. A few weeks ago, however, my wife's Macbook stopped connecting. I've tried a number of things (reconfiguring, restarts, reinstalling the last combo updates, etc.) and the only thing that appears to work is dropping the AE to 2.4GHz (I still keep it at 802.11n-only). My Macbook continues to be able to connect just fine at 5GHz, when I enable that on the AE.
Considering that this drops our available bandwidth from 300Mbps to 130Mbps, I'm not a happy camper, but I'm also tapped out of ideas. I can only guess that there's a hardware malfunction on my wife's Macbook. Her Applecare doesn't expire until 2010, so I may just take it in ...
Any ideas? One note: my wife is still clinging to Tiger, while I'm on Leopard ... in case that matters.
Thanks,
Brice

Not that I can tell. Suspiciously, we did run a salvo of updates from Software Update and the problems started immediately after, but none of those appeared to be directly related to Airport functionality (firmware or otherwise). Just to be sure, I took the "safe" steps of repairing permissions, re-downloading the last combo update & re-applying it. I also searched for any firmware updates related to Airport. What's odd to me is that the firmware reported on her machine is different than that on mine. They're both Late 2006 Macbook models, so that strikes me as odd (but maybe it isn't). I wasn't able to find any updates that her Macbook was lacking, however.
My (working) firmware is: [type] AirPort Extreme (0x168C, 0x87), [version] 1.4.8.0
Her (not-working) firmware is: [type] AirPort Extreme (0x168C, 0x87), [version] 1.4.4
Based on the card type, it doesn't appear that they're different chipsets, so I'm not at all clear on why the firmware versions differ. Was there a firmware update for Leopard that wasn't available/needed for Tiger?
Also, I know for sure that there were no firmware updates performed during the last set of updates ... that's a more involved process, if I recall, not handled through the standard updater, I think.
Thanks for the response!

Cisco Aironet AIR-SAP2602I-E-K9 WAP -ERROR: VLAN 1000 doesn't exist on 'Radio1-802.11N 5GHZ' (see Services VLAN)

Hey guys,
I'm configuring my access points with two SSID's through the GUI. The first is a corporate SSID and the second a guest SSID. The corporate SSID needs to be attached to native VLAN 1000. The guest SSID needs to be attached to VLAN 1234. Both SSID's / VLAN's are to use WPAv2 AES CCMP with a PSK. Although I'm getting an error message indicating that my VLAN's don't exist on ‘Radio1-802.11N 5GHZ’ . Here are steps I take from start to error...
Create SSID’s with no security. CORP not to broadcast. Set CORP to use native VLAN 1000. Set guest to use VLAN1234.
Within security encryption manager > Set encryption mode cipher to AES CCMP on both VLAN 1000 and VLAN1234.
Within services > VLAN check that both VLAN’s have Radio0-802.11N 2.4GHZ and Radio1-802.11N 5GHZ selected. They do.
Within Security > SSID Manager – set client authenticated key management to mandatory, enable WPA – WPAv2. Set pre-shared key. Hit apply > “ERROR: VLAN 1000 doesn’t exist on ‘Radio1-802.11N 5GHZ’ (see Services > VLAN).
I get the same error for both SSID’s. Radio1-802.11N 5GHZ is "checked" against both VLAN's. Am I missing something? Both Radio0-802.11N 2.4GHZ and Radio1-802.11N 5GHZ are enable interfaces and are "up".
I'm pretty customed to switch and router IOS although have absolutely no exposure to WAP CLI.
Any assistance appreciated.

I've resolved this myself. The GUI is basically terrible and very buggy. I used the CLI and was able to add WPA through the CLI.

Need Help with extending Airport Extreme w/802.11n

I would like to find a way, if there is one, to extend the coverage of my Airport Extreme w/802.11n. My object is to be able to share my home network with a 2nd house on my property which is approx. 90-100' away from main house and Airport Extreme w/802.11n base station. This home base station is connected to my iMac and I would like to extend it to allow my Dell PC w/ Win XP in 2nd house to connect to the internet/share files/share printer.
Is this possible and what would I need on the PC side to accomplish this wirelessly?
Thank You in advance for your help.
Daniel

Is the 2nd house on a the same electrical box as the main house? If it's the same, then you can try the powerline ethernet solution.

You will find it cheaper than most outdoor point-to-point bridge solutions.

Best way to configure Airport Extreme Gigabit 802.11n

Hi, new to this router stuff. Just bought the Airport Extreme Gigabit 802.11n. Seems to be working much better than my old router furnished by my cable company. Still, wondering how to get the most out of it. So, have a few questions...
1. How do I know If I'm getting the "n" connection. Don't know if the modem they gave me works with this. Is there a way to see which connection is working? G/B/N?
2. Channels: I'm on 6 by default. Is it worth trying others to see if one is faster than another? How?
3. Firewall: I was told the router already has a firewall in it. So, turned off the firewall on my mac 24. If true, do I still need to configure this firewall on the router side? HOw? To what? Don't know the best configuration to use as a rookie.
4. Any other ideas to tweek this baby to get the most out of it?
Thanks all. I'll defer to the experts now.

Please check out the following Apple Support article for details on the various options available to you with using multiple base stations for extending a wireless network. If you have any questions or need further assistance please don't hesitate to post back.

when will airport express support 802.11ac

We are all users here on a user-to-user support forum......just like you.....so no one here will have any idea about what a notoriously secretive company like Apple might do, or when they might do it.
If Apple makes an official announcement regarding a new product, then we will all know.
