I have a desktop and a laptop computer; i connect to the Internet using a Belkin router, (cable to the desktop) and Belkin network card (F5D7010) to the laptop. Just recently, an annoying problem; I get a "no connectivity" report on my laptop, after a few hours of use. The only way to reconnect is to restart the laptop. This problem has only happened recently. I wondered if there might be a fault in the card?
