I had this problem with belkin router with the signal only being around the 40 - 50% mark using the usb adapter. Sometimes it wouldn't connect to the net, and I had to reboot, and once connected, sometimes it would drop the connection. I changed to the network card and while it was more stable, signal strength was still low and it stilled dropped.

After many chats with belkin support, they finally said the only thing that would help is have the second pc nearer to the router and if this was not an option, then I could buy a range extender that they now have, except that it would only work with certain models and mine was not one of them. They said the distances acceptable for the wireless to work without problems were achieved under laboratory conditions and so vary as to my setup.

In the end, I ditched wireless and cabled the pc's.
Will go for a different router eventually.
