Dell Inspiron 660 - 64 bit - Windows 7 Home Premium using AT&T 2wire 642 interface will not allow upgrading to more secure encryption of WPA OR WPA2 on a friend's home system. When I tried to change it from WEP to WPA or WPA2 wireless setup, lost all internet connectivity. The 10 digit encryption key is provided by AT&T with their broadband interface.
She is running Windows 7 Home Premium, SP1. All updates are current.
Any ideas how I can help them fix this? WEP is completely unacceptable security.
Thanks a ton.
