Working on my brother-in-law’s Dell laptop computer that is running Windows 7. He can not get onto the internet via wireless connection. Previously there was no problem connecting. Tried re-booting their modem and router.
Brought the Dell home to see if I could connect to my WiFi, but again no luck. When I open “Network and Sharing Center” and click on “Connect to a network” it shows “Not connected” and either “Troubleshoot” or “Open Network and Sharing Center”. A BIG fat loop and loop and loop.
In “Mange wireless networks” both his and my networks are listed.
Went to Network Connections to see if the NIC was enabled and found "Local Area Connection", "Local Area Connection 2", and "Wireless Network Conncection". I "Disable", then "Enable" all three. On the Wireless I then clicked on "Connect/Disconnect" which brought me back to the "Not connected" window with the "Troubleshoot" and "Open Network and Sharing Center" options.
I decided to use "Restore", but found it turned off and no restore point available.
I am running out of ideas, any suggestions?
