Hi, I'm a techie neophyte running a Belkin N1 router with about 10 machines connected (XP desktop, a few xp laptops, and a bunch of mac laptops), mostly wirelessly. A couple days ago all of a sudden noone could see the network wirelessly. I called belkin today and they had me upgrade the firmware to a "beta" version. It had some problems but appears ok now. However, now my laptop has that "unable to find a certificate to log you on..." error message. But it still surfs just fine (is this normal?!?). The time on the router and laptop are within a few minutes of each other. They are both set to WPA-PSK (no server), and both using TKIP only. Is this something that I need to worry about? thanks for any insight you can give
