Tp link wireless validating identity problem
I have two XP laptops at home that were both working fine for weeks with a new Cisco wireless router, then suddenly they both say "Limited or No Connectivity." Both of these laptops work fine with another wireless router.In order to configure the connection back to Automatic, edit the eduroam profile, go to the Connection tab and check Connect when this network is in range: Figure 14: Setting Automatic connection  = If the Wireless Network Connection icon is not present, this may be due to the wireless network manager of your vendor's card taking over from Windows' built-in one (Wireless Zero Configuration).
To resolve i went to the manufacturer site and downloaded the latest drivers for the wireless card, and any other drivers i could.

Enter your username and password (same as your email account). The username should be “MIDD\your_username”(MIDD\tsmith for example) You should now be connected to the Middlebury College network!
