Wifi for laptop not connecting to network/internet
Hi. I'm using a Gateway NV54 laptop and the wifi isn't connecting to the home network or internet. The wifi worked before the install, but not after. I have another laptop and the wifi works fine for it.
Recently did a clean install of Windows 7 Home Premium SP1, 64-bit. Installed all drivers. Current wireless driver is Intel Wireless LAN Driver (since the laptop uses Intel Pentium processor).
When I click my home network in the list of connections it asks for the security key. I put in the key and immediately it says "windows was unable to connect to this network." Tried this multiple times. I can connect with ethernet but not wireless.
Tried pressing Xfinity router wireless button to pick up the laptop but it didn't work. Tried logging into Xfinity router from the other computer and manually put the laptop's computer name and mac address into router, restarted router, still can't connect.
Any ideas? Thanks.
