I have had the worst time trying to setup a wireless range expander. I can not get the red light to go off at all. I have exchanged out the range expander 2 times already, I am going to exchange another today. I have spent a total of 5 hours on the phone talking to the sorry Linksys Tech support. That had me doing the same thing for about 4 hours. I have tried all different kinds of firmware. I am at a point now that I do not know what else to do. I have joined this forum in hopes that my nightmare will be solved. My routers are WRT54G and the wrt54gs. I have even place all of the antennas of the routers and range expander within centimeters of each other and yet they still cant find the range expander. Please help I am almost at the point of tears now.
