iPad and iPod with iOS 4.2.1 no longer working

Yesterday I upgraded my iPad to iOS 4.2.1. Ever since the upgrade the wireless is mostly useless. I can reset the network settings and connect to our Aruba powered wireless network and it will work fine for about 1 minute. After that the wireless is stuck. I can't use it, and it can't see any access points until I start over.

This morning we upgraded a new iPod Touch to 4.2.1 and it is displaying the same issue.

As a test, I connected to a Netgear powered SSID and it works fine. I also connected to a Linksys AP and it too works fine. However if I disconnect from those AP's and connect to the Aruba AP, 1 minute later I have no wireless network any more.

Anyway, I was wondering if anyone else was seeing these issues?

Re: iPad and iPod with iOS 4.2.1 no longer working

What type of encryption are you using on the SSID that does not work? We have had comments on quite a few upgrades working correctly at Corporate.

Re: iPad and iPod with iOS 4.2.1 no longer working

We have miltiple SSIDs. One with no encryption and one I think is WPA2. Neither of them work for more than a minute or two.

I also had a co-worker try his iPhone 4 that was upgraded. He had the same result. No wi-fi after connecting to our un-encrypted network.

You need to turn on user debugging for that mac address and post the results or open a tac case:

config t
logging level debug user-debug
show log user-debug all

Re: iPad and iPod with iOS 4.2.1 no longer working

My testing today the iPhone 3GS on iOS 4.2 is working fine on the corporate network here, using WPA2-enterprise. I'm currently streaming pandora as an example, that's been on four about 5 minutes now without an issue. Last night I had both the iPhone and iPad on a WPA2-PSK Aruba WLAN without issue, I was able to stream Netflix to the iPad.

Can you test with a device on older code? Any chance you've got a security appliance that is able to figure out your device after the 4.2 upgrade and is setup to take action against it? Any other devices having issues? Can you confirm your encryption and auth types?

Re: iPad and iPod with iOS 4.2.1 no longer working

I had to stop the music for a quick meeting with a coworker, when I went to unlock the iPhone it was on 3G, but as soon as I unlocked it went back to Wi-Fi. I assume this is different than what you've observed correct?

Re: iPad and iPod with iOS 4.2.1 no longer working

We are having the same problem with iPads after upgrading them to 4.2.1 they will not connect to our WPA2 Enterprise authenticating to AD but they work fine on every other equipment just not Aruba. Weird thing is that iPhones upgraded to 4.2.1 work just fine, I don't have an iPod Touch to try. We can connect to Linksys and Dlink APs with no encryption all the way up to WPA2 w/o 802.1x auth.
I tried Apple as it looks to be iPad with 4.2.1 specific but all they could do is swap the device to get us back to a 3.2 version, as you can not downgrade once you go up to 4.2.1 code.
There is definitely something going on here.

We have both WEP and WPA2 Enterprise encryptions.

We have tested the iPad, iPhone4 and iPod Touch (3rd Gen) on our network after upgrading to iOS4.2.1 and we're experiencing connectivity difficulties as mentioned above with other users.

After a reboot (or network reset) of the iDevice, it will detect our WEP / WPA2 SSID and connect to it. However, after a few minutes, it will drop the connection but still keep the wireless icon on the status bar. When trying to access any data, you get a not connected error (or will default to 3G connection).

If you attempt to reconnect the device, it doesn't see the wireless SSIDs. If you try to manually configure the SSID, you get a "Could not scan for wireless networks" error.

None of these devices are jailbroken. All have been identified working outside our network properly.

Any device prior to the 4.2.1 iOS works fine.

NOTE: In some cases, when a client resets the network settings, it will connect and continue working without issue until you cycle the WiFi switch or enter an elevator (low signal strength), then the above issue starts up.

Re: iPad and iPod with iOS 4.2.1 no longer working

Can everyone who is having this issue, please turn on debugging as instructed in comment #4 http://airheads.arubanetworks.com/vBulletin/showpost.php?p=8696&postcount=4 and post the debug logs for that individual client. Otherwise, please open a TAC case.

I would also encourage you at the same time to either open an Apple case or post it on their boards, so others can help resolve this, as well.
