When I leave my laptop and the screen saver is on for some time and I return to the computer, it always drops the wireless connection. It will say from the "Wireless Network connection" very good signal strength, and show 100% connection with my D Link 614 router with my Linksys WPC54g card, but it won't surf. This problem has recently started and no new software nor firmware upgrades have been performed. I do have the latest firmware/drivers for all the devices. This happens when teh computer is plugged in also, and under my power schemes, the only thing that turns off when plugged in is monitor. All the rest are set to Never.

Thanks
