I just bought a new linksys Wirelss G Broadband Router. I've picked up wireless internet on my pc in the past, but I'm having trouble now. My laptop is a 2218RS Presario. There is a wireless button on the front of it that is supposed to light up when it is on. However it is not lighting up when I push it. So obviously I think this is the problem. Question is what can I do about it?
