Can't join home network after upgrade to iOS 6

I upgraded my iPhone 4s as well as my iPad 3 to iOS 6 while I was at work today. Everything seemed to work fine while I was at work. I was able to log onto the wireless there without a problem. When I got home however, I was unable to join my home wifi. I get the very helpful message "Unable to join the network "<network name>". My network worked fine prior to the upgrade, and still works for my wife's iPhone 4 and our original iPad. The only thing that changed what the update to iOS 6.


Here is my setup:

Netgear WGT624 v3 wireles router with the latest firmware

WPA-PSK [TKIP] + WPA2-PSK [AES]

iPhone 4s running iOS 6.0 (upgraded from 5.1.1 over the air)

iPad 3 running iOS 6.0 (upgraded from 5.1.1 over the air)


I have already tried forgetting the network, resetting all network setting, doing a soft reset, and a half dozen other fixes to try to get it to work with no luck


Anyone have any ideas or are having the same problem?


Thanks

iPhone 4S, iOS 6

I had this same problem with my Netgear WGT624v3. As I'm just using this as a wireless access point and I also have a Linksys WAG160n, I re-enabled the WiFi on this as well to see if I could connect to this in the interim. Alas this gave the same problem (i.e. unable to connect to the WiFi message). So I think there are a few other routers other than the Netgear routers listed above that are giving this same issue that is different to the more general iOS6 wifi issue that is widely documented elsewhere. Hopefully with a wider pool of routers impacted by this, Apple will be encouraged to do something about it.


My "fix" for this issue was to download the iOS 5.1.1 IPSW package and downgrade my iPhone 4S back to the previous operating system. I would stress that this was a painful process and not one people should take lightly. However at least it put me back to where I was previously with a setup that I had working before and I can then consider upgrading back to iOS 6 once this is fixed.

My setup (office LAN with 3 AP:s Netgear WAG102, firmware V2.0.16)

Access from iPhone4S/iPad2:s terminated with upgrading to iOS6, while other un-upgraded iOS-units with 5.1.1 still accessing smoothly.


My solution: Router firmware V2.0.16 downgraded to V2.0.12 (extracted from download.netgear.com).

Result: iOS6-units back in WLAN-business.

Double-checked by re-upgrading AP:s to firmware V2.0.16 resulting again in no-access from iOS6-units.

Now the older V2.0.12 will prevail in our AP:s until news is spread about iOS6-fixes or new iOS6-compatible firmware from Netgear.

I can also confirm that downgrading the firmware to v21 fixed the issue for me with my Netgear WGT624v3. As an experiement, I tried to use firmware v25, but it looks like whatever is hindering the connectiong was instantiated in v25, as it results in the same error message as v26. For now, v21 works until Apple can come out with a patch.


Thanks for all the help people!

Crewhughes,


Your issue is not the same as the issue being reported in this thread, though it may superficially appear to be the same issue. Changing (and indeed, trying ALL of) the router channels was one of the earlier fixes tried which did not solve the problem for people affected by the issue in this thread.


(Incidentally, downgrading the router firmware does not change the channel on the router. Settings are generally preserved across a downgrade, so downgraded routers broadcast on the same channel as they did on newer firmware. I am currently using my Netgear router on channel 11 with older firmware, and it works just fine. It did not work with the newer firmware on any channel at all.)


Your router issue has something to do with channels, or potentially the sensitivity of your device to potential channel interference. Our router issue is not solved by changing channels and, in fact, the router logs are showing us that it is an unsupported request being made by iOS 6 on new Apple hardware that is the problem--not an incompatibility across channels.

Hi all

I did the firmware downgrade on my WG102 - BUT still having ongoing issues and were curious if others were experiencing the following:

1. My iOS6 devices connect....but after some period of time seem to lose their connectivity - they still appear to be connected (with an IP address) and wifi icon on top of screen - however, if you try to web browse.....nothing loads.

2. My MacBook Air initially connects....but once it goes to sleep, it can't reconnect and gets an ! where the wifi icon is.


Only solution to both these problems is to reboot or powercycle the WG102. Anyone else have similar issues or thoughts?

thx
