bridging sucks stay away from it.. You will half the speed of the routers and none of the newer ones support better then wep encryption when trying it... they all list wpa, but will fall back to wep only for bridging.
You want a gaming adapter/ethernet converter
Buffalo had great ethernet converters but got sued into oblivion....
these were great
old buffalo ethernet converter, still using one in my basement now. 4 port switch built in.
Your other option if to buy a gaming adapter similar to a
Dlink Gaming adapter They appear to be the more modern version of the older
dlink G820's. I'm still using one of those on a desktop i just dont feel liking running cable to.
I have personally started using ethernet over power lines.
Netgear powerline kit These are hit and miss though as it all depends on your wiring. There is no way to test except to buy them and try it out. I would recommend buying locally so you could return them if they don't work with your home's wiring. And only get the newer 200mbps ones.. you'll never see that speed, but the 85mbps once have much less bandwidth.
I was only getting 10mbps (of my fios 20mb) with the buffalo wireless convert to my upstairs office. Can now max out my bandwidth. They are testy though.. If i plug certain additional electronics into the wall outlet on the right side of my room I can knock out the link between them. I assume most of the bad reviews are for things like this.. bad wiring, noisy/poor/dirty signal electronic devices.. etc
I even lost sync once when i left a computer power cable plugged in, but not plugged into the computer, guess it didn't like the unterminated line. Where as my wife's phone charger can be plugged in with no issues...
I've been so pleased I'm going to replace the last buffalo converter I have in teh basement with an additional powerline unit. Hopefully I don't have any strange electrical issues between the other two currently in use.
