I've been posting quite a bit lately as to suggestions as to how to speed up my network. Whatever I do, I cannot get to my iMac to connect to my network faster than 5-10 Mbits/sec. If I step 6 inches out of the room with the iMac, I get 70-100 Mbit/sec. I've finally come to the conclusion that there is some type of interference in the room with the iMac and no matter what I try, I'm not going to be able to get good wireless network speeds in that room. Since the room is on a different level than my wireless router, a direct wired connection from my Time Capsule is out of the question. But, what if I bought an Airport Express, put it right outside the room with the iMac and ran an ethernet cable from the Airport Express directly into my iMac? Would that have any positive effect? Could that help my iMac's throughput?
