Vista - Intermittant linksys router problem

Hi All,

The problem that I am having is very strange and does not happen very often. When I, or my room mate try and connect to our wireless network it will try to connect and never get an IP address and fail t connect. The only resolution to this is to unplug the router and then it works just fine. Router is less than a year old and up to date with the latest official Linksys firmware. Also this seems to happen after long nights of torrenting. Is there anything that I can do to fix this?

Also on another side note I have been toying with the idea to get a commercial grade router for our house, since we house a couple of geeks we use a lot of bandwidth, any suggestions as to commercial grade wireless routers.

Thanks,

A
