Yes, taking WGT624 V3 to 2.021 worked for me as well.
I can confirm these issues also. I have had three users (including myself) update to iOS 6 today and each was unable to join any of our wireless networks after update. The iOS devices in my case were 2 iPhone 4S phones and 1 iPad 3. After this was first reported by the iPad user, I performed an update on my 4S to confirm the issue was not localized to his iPad. I was connected before update (obviously, since i was able to update) but unable after updating. We have attempted the following to remedy the issue:
Multiple reboots of iOS devices
Multiple reboots of WAP
Changing WAP channel
Changing WAP from multi-band to single band
Adding an unsecured security channel.
Nothing has solved this issue. Additionally, one user with a iPhone 4 has also updated but did not experience the same issue.
If anyone has any suggestions, I would be happy to hear them. (As long as UA, PEBKAC, and loose nut on the the keyboard are not included in the diagnosis.)
I can confirm. Resetting the router and performing a full reset/restore of the iPad did not solve the issue. iPhone 4 updated just fine. iPad conects to other open wireless networks, but not to the WPA2 network at home. Checked router settings, everything is fine. iPad worked fine under OS 5.
Clearly this is a change in iOS6. Waiting on a fix or official statement from Apple.
Exact same problem here. I updated my iPad 3 to IOS6 and wifi stopped working. I updated my iPhone 4 and it continues to connect to wifi...I am not sure what to do from here. It appears to be iPhone 4S's and iPad 3's that have the wifi issue. I have several people connected to the wireless router and it is working fine. There are no DHCP issues either. I am curious where to go from here!
I'm having this problem with my iPad 2. It will allow me to choose my network but then gives me a Yahoo error page and will not connect. I have several other devices connected to my network, as always, and there are no problems. I have not updated my iPhone 4S yet and will not until this is figured out.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Unable to Connect After iOS Update - saw this solution on another post.
Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
If any of the above solutions work, please post back what solved your problem. It will help others with the same problem.
I have a similar issue. IPad connects to WiFi and then drops after a few minutes. If I go into the mail app, it reconnects, but Safari, or downloading apps from the App Store, will not keep the connection up. I reset the Network settings, and have rebooted. This is happening in a known environment that was very stable until the iOS5 upgrade.
I think its pretty simple this is dfinitely a ios 6 issue cause we all had perfectly working ipads and iphones with ios 5 prior to the update this morning, and if other devices are connecting fine...which 5 of my other wi-fi devices all connect perfect, from laptops to a*droid devices then all we can do it sit now with are useless non functional expensive apple product devices and wait for a fix!
this was an issue in the beta version and still is now.
