I have two machines with Windows VIsta SP 2 that cannot identify the wireless networks in the shop or anywhere else.
They are both fresh installs with the latest drivers and Atheros AR6007 802.11b/g Wifi adapters. THey are able to connect using an ethernet cable. I have tried the following:
1. Set static IP
2. Set MAC Address
3. Using different driver versions
4. Uncheck IPv6 on both the wireless and ethernet adapter
5. Disable the DHCP Broadcast
