Hi Xanax,
I posted this early in the week:
"I picked up the Linksys BEFW11S4 4-port wireless router ($99) this weekend and hooked up my wifes PC with a wireless Linksys PCI card. Easy to setup and works great. I played AH and Raven Shield on it with no lag. Seemed as fast as my direct connect. Now I will pick up a Linksys WET11 and hook up my Xbox wirelessly. My wife will be so pleased not to have a 30' network cable laying across the floor. "
I've seen no packet loss or speed reduction as compared to my direct connection. Overall I'm very pleased with my wireless connection. I never thought it would be this smooth.
