Thanks for the replies, guys. I've done some testing the past few days, and it looks like the only direction that takes out my internet is NE, which is right in line with my modem and router. The modem/router sits about 45' from the tower in the other room. Unfortunately, because of where the internet enters the house, it's not practical to move it. Thinking out of the box here, is there any way to shield the modem and router with some kind of contraption or cover to keep the RF out? Any other suggestions? I don't think wireless is an option since it completely kills the internet.
