You may want to read this webpage from Techtv. I also use the Linksys BEFW11S4. Wep did affect the performance of my wireless network my estimate was about 25%. Techtv claims as high as 50% performance loss.

Linksys usually comes with ZoneAlarm firewall which i don't use i have Nortons Firewall. If Microsoft and NASA can be hacked what would they want with me? hehe [img]smile.gif[/img]
