I only had one bad experience with a Linksys product.
I had a D-Link router in place for about a year and played online games all the time...no problems.
I went out and bought the Linksys BEFW11S4 wireless router/gateway so that I could get even more lazy and play Warcraft on my laptop in the living room while watching TV. After every game, I would get kicked off of game servers. I never had this problem with any other router/gateway that I had in place so I placed the D-Link back in it's place and made another collision domain out of the Linksys router. Haven't had any problems since.
Later I found that I had to tweak the wireless a little to get it to work a little better...
You'll also find that you'll have a lot of cool stuff to tweak with it.
In my opinion, excellent buy!
