No Wireless Connection

My cable modem was down for about 12 hours yesterday, but it's now up and running on my desktop, but my laptop will not recognize the wireless signal from the router. I called Gateway (laptop manufacturer) and Charter (internet provider) and they suggested that I should call Hawking. I really hate being on the phone for long periods of time, and it's Christmas Eve, so I thought I'd post here first. I've recycled the power a couple of dozen times with no luck, and tried to reset the router but I don't know if it worked or not? Can anyone help me? I would greatly appreciate it! Thank you!
