Here is a description of my situation:
I have a client with a LARGE home (40,000 sq ft.). When I tried to install ONE wireless router, the connection in the upstaris office was sometimes VERY GOOD, sometimes NON-EXISTENT. I tried three renge extenders, and still had the same problem. . .
ROUTER = LINKSYS WRT54G
Please keep in mind that hard wiring is IMPOSSIBLE.
My end solution was to "bridge" three networks using wireless gaming adapters. The result was three seperate wireless networks called DOWNSTAIRS, MAIN_FLOOR, and UPSTAIRS. The DOWNSTAIRS network is hooked into the cable modem and broadcasts an IP to the MAIN_FLOOR network. The MAIN_FLOOR network does the same to the UPSTAIRS network. I was able to accomplish this using MAC address filters and configuring the gaming adapters properly.
Now, finally, to the problem.
The signal still cuts out. I positioned the routers PERFECTLY so that they are never more than 175ft. away from each other. What can I try to fix my problem.
