I don't know why I tried this but I was amazed that it worked. Before trying this I was getting 60%-80% signal strength from my DIR655 router via wireless N. I removed the center antenna and now I'm getting 98%-100% signal strength from/to my laptop.
So would anyone hazzard a guess as to why this would be? Not that I'm complaining here but thought I'd pass it along. The router is lying horizontal with its two outter antennas now pointing straight up.
