Today I built the #1 computer below and everything's fine except my download speeds. ATT speed testing indicates about 1.5-2.5 Mbps, while the computer sitting next to it that is plugged into the same gateway is getting a little better than 11 Mbps. Surfing appears OK but it's virtually impossible to download anything. Called ATT and they're sending someone over to check their equipment but I wanted to ask if there's anything in the computer setup that would cause this that I can change. Thanks for ideas.
