So, the internet comes into my house in the attic of the top floor... cause Comcast hates me I guess. We've run wires under the floor, so the upstairs is all networked. Then, dad put a computer in the basement because it's not so hot down there, so we ran a wire outside the house down into the basement. Now, the wife and I have moved back in, but we've taken over half of the main floor instead of upstairs where I used to live when I was younger, and there are no network cables at all on the main floor (house is: basement, main, upstairs). I'm on wireless right now, and it's slow/laggy as can be. I have a wireless-N router that I'm going to put in, but I don't have 100% faith in that either. Mom doesn't want any more holes drilled, and I don't blame her, so the easiest thing to do to get a wire would be to put a switch in the basement, then run a wire through the heating ducts to the main floor. We have three computers on the main floor, so I might need a second switch to hook them all up. Is that going to give me issues and/or should I just stick with the 802.11n?
