The antennas were unplugged on the laptop. The poor owner had been living in agony for months. Bizarre...
Sorry but there is so little detail in your post but it appears it's not the router?
For a while now, I have experienced low signal strength with my wireless router (LinkSys WRTS4GS) to my desktop. There are 2 other PCs that connect to the same router with high signal strength when being almost 30 feet away, however mine is the closest, though directly above the router. I can barely achieve a 2 bar signal strength while my desktop is less than 8 feet away. I checked for devices that may cause signal interference and unplugged all nearest the connection between the router and computer. These caused no change. At times I can't even connect, for example right now, that's why I am typing this on a different computer. Please help me resolve my problem.
