My laptop isn't picking up the wireless connection from the router. The other laptop in the house picks it up fine, and mine was too until last night. I changed nothing, but the screen started flickering and the laptop suddenly wouldn't recognise the battery charger. I fidgeted with it and fixed this problem, but the laptop is still not accessing the Internet. It doesn't even pick up the signal. Any suggestions?
P.S. I don't have a wireless switch on my model - it's a Dell Latitude D610. My router is a Linksys 2.4GHz. I even tried restoring the system to an earlier checkpoint with no luck. Please, any help would be appreciated.
