Hi all,

Tearing my hair out here.. just bought a new TP-Link 8960N for my parents and am finding that while the wireless is working fine for their windows 7 laptop, it doesn't work properly for their older windows XP laptop.

The older laptop works on wifi if I set up the wifi with no security/encryption, but as soon as I add security (WEP, WPA, WPA2) it connects to the network, but can't ping anything on the network and DNS lookups fail. 

Any ideas?
