How about a long ****ing ethernet cable?

Im assuming they're gaming....gaming with wireless is dookie.

They're a full alternative to wireless. It would look something like this:

Wifi Router --(ethernet cable)--> Powerline Adapter --(electrical system in the house)--> Powerline Adapter --(ethernet cable)--> Roommate's computer

They are very simple, plug one into any outlet by your router. Plug an ethernet cable into router and the wall plug. Plug the second one anywhere else in the house/apartment/building and run an ethernet cable from it to any other unit that accepts an ethernet cable (nic card, router, wireless router).

Keep in mind they say they must be plugged directly into wall, you can't have it plugged into a surge protector or anything else. Which is why I recommend the one that has a pass through so you can continue to use the plug in. Also I think some of them actually will block both plug in because they are a little bulky. Just read the comments. I think most people tell you in the comments on each one.

Good info in this thread. I may try one of those power adapters as I'm having a similar problem except with my tv playing Netflix. It's constantly buffering when using wifi.

I'll state the obvious as well, Comcast is complete garbage coming from Google Fiber. I've spoken to Comcast reps more in the 4 weeks I've had them than I did the entire 3 years I was with Google. From flubbing the install date causing a 5 day delay in hook up, to service drops (I work from home through vpn), tuning errors when trying to change channels, and can't-do-anything-but-laugh customer service. Just a complete junk product in comparison.
