I have a small problem. There is a network of 3 computer (2 WinXP Home and 1 Win2K). In room number one is a Cable Modem, Wireless Router and a Computer. The setup comes into the modem, then to the router and hard wired to the computer running XP. In room number 2 is a computer that holds a signal of 97% and runs Win2K and finally another computer in room 3 that runs XP and holds a signal of 87 - 92%.

The Router US Robotics (USR8022)
The Wireless Cards Belkin w/ external antenna

The Problem, Computers 2 & 3 are being dropped from the network on multiple occasions and the users usually have to reset both the router and the modem in order to reconnect. I'm not quite sure if Computer 1 completely drops signal, but I could find out. Is there any suggestions on why this would happen?

I had a similar setup and never had this issue.
