I opened a trouble ticket yesterday evening to Netgear and during the night a new Firmware has been added online. Old Firmware 2.0.16, newest 2.0.7. All my WAG102 access points have been upgraded, the bug is fixed. Thanks to the Netgear support team !
the firmware 2.0.7 is the older one (it's from 2007) and 2.0.16 from 2010. But you are right... iOS6 works again with the older firmware 2.0.7. The downgrade was possible without any problems in my case.
I will try 2.0.16 again with a new iOS6 Release (e.g. iOS 6.0.1).
I had the same trouble today. I sinced up my iPad and the iOS upgraded and was not able to connect to WAG102. It showed in the WiFi connections. But would not connect to that network. Downgraded to 2.0.7 from 2.0.16 and now I'm able to access my network. Thanks for the posts. Now Apple needs to fix the problem on there end.
