Setup: Linksys BEFW11S4 v4 with lastest firmware. WEP enabled. 3 XP desktops (D-link adapter) and 1 win 2000 laptop (Cisco adapter) all connected wirelessly. Everything works fine for a couple of days and then suddenly, the wireless connection is lost on all clients. Light on the router says wireless is working. Also adapter wireless utlities and Netstumbler show the wireless as active. However, I cannot connect to it. I have to power off the router and power on and things are normal (for another couple of days ) Any ideas ? Thanks.
