I used to connect at 300 but that's within 10 feet of the router, I don't anymore it's so finicky to maintain 300Mbit. I am only realting that to the environment around the placement of the router and I have a G client which uses a linksys 108Mbit usb dongle. Wierd thing though, is that even though it says it's G, if I set the router to N only, the G card still connects and shows up as N in the router. So I don't know about the technology behind it, but wondering if I should just keep it at N.

Anyways, that's my tidbit. If it's not a compatibility issue then it's the environment, maybe even both.
