I've been having problems with my wireless network dropping. It happens regularly when watching video's or pictures from my laptop that are on a USB 2.0 external hardrive hooked up to my pc. I have a Linksys Wireless G router. I have a Dell Inspiron 2650 laptop with a Linksys wireless card, and a Dell 4550 Desktop with a wireless adapter. I have WPA PSK enabled, and have DHCP turned off with static ip's on both computers. Is this caused by the router, or just because it is on the external hardrive?
