That message is not unheard of when WEP and/or mac filtering is enabled and the password is wrong or the mac is not allowed. Did you check that out?
Ever since my husband installed the Netgear N600 router, I can no longer get an internet connection on my laptop which is running Windows Vista. He's running XP and he can connect no problem on his laptop. My connection appears to grant me access, but when I hover over the network connection it says local access only. The error message I get is "unidentified network." Has anyone else experienced this? Am I going to have to buy Windows 7 in order to get internet again? Please assist and thank you!
