I have Desktop A upstairs unto which a wireless router is connected for various devices. Downstairs I have a laptop that I use to connect to the wireless network. I also have Desktop B downstairs. I have an ethernet cable connected from my laptop to Desktop B. There is no drop downstairs so I wanted to connect the desktop somehow. I've enabled the wireless adapter to allow other computers to use its connection to connect to the internet. However, 2-4 times a day the connection simply stops. I don't have any of the computers on Homegroups or anything. Any idea what I may be missing? All network drivers for all devices (wireless and wired) are updated. Using a Belkin N3000 wireless router.
