I picked up the DLink 200mbit adaptors for the apartment I'm in, and with 4 of them plugged in at various parts in the apartment, I'm getting a reliable 50mbit speed. I haven't done much fiddling with them yet, as a stable 50mbit connection has been better then wireless thus far.

I think once a firmware update ships for my dual band router to go to Draft 2 N, I may go back to wireless on the N equipment I have. The 5ghz range is nice and clear currently, so speeds there could probably average near 100mgit.
