I've found over the last few years of using wireless and going through many routers, that the stability is still way too random sometimes. Especially for torrenting and having more than two connections.

Seriously, if you want to torrent and download large files, just go wired and let the non-hardcore users use wireless. I have a Netgear DG834G at the moment and it is really great for casual Internet users, but I have it wired to my main PC to download a lot of stuff (because it was just too random on torrents).

Who knows, maybe someone has some godly new router that is extremely stable and everything, and I certainly haven't tried any of the N wireless.
