I would say Linksys would be my top choice... I have an older wired router by them and it's been great. And, as much as I hate to say it, I have a D-Link wireless Access Point which as been great! Out lasted 2 of my D-Link cards too! LOL
actually Dlink has moved up in performance and stabability in the last year. For the price the DI-524 ($19us after rebates) hard to beat as both wireless and/or fixed.
the same thing you need to use it in a room in your house. Most wireless systems range about 300 feet from source to source depending on how many walls and what type along with whether there are any flourescent lights floating about, as these do have a tendency to interfere a little.
