How to stop Belkin 802.11g Wireless Router from Dropping Connection

Im having problems with my home network. I am broadcasting my SSID in a built up area, and set my (2) PCs to connect wirelessly to it. However, the connection seems to drop on a regular basis and usually requires a manual repair (via windows) on the connection to get it back. I have tried changing the channel that the router broadcasts on and also tried stopping the Wireless Zero Config service, but these dont seem to make a difference. I want to get the PCs to stay connected to my network for the duration that they are on. Can anyone help?
