A friend has a shop that is located about 50 ft from his house. I have located the modem and Linksys 802.11b router as close as possible with it also being on the top floor near a window. There is a computer inside that works fine and there is a Dell in the shop outside. The Dell has an external USB Linksys 802.11b card. When I was there it connected and worked fine and had a "good" signal which was about half. Then a few days later it stopped connecting. When the PC restarts the Insight software crap doesnt connect anymore. I havent been out there lately, but think the problem is related to signal strength. What is an easy and inexpensive solution for this problem?
