I have a d-link wireless router in my home using comcast cable with three laptops using it wirelessly. No problems until last week. My daughters latitude CPxH 650 with a d-link wireless card started dropping offline at random times. I could restart the laptop, and it would pick up the connection. Today, that stopped working. I checked the wireless card, and it shows to be working properly. The drivers are the latest. I have checked everything I can think of. It connected once tonight, stayed connected for about ten minutes, then dropped it. I can't get it to come back up for anything. Any suggestions or comments will be appreciated.
