I recently bought two Belkin F5D7320 (v8000, latest firmware) Wireless G routers, and I'm having a very strange problem. I set one up to use WPA-PSK. Using my laptop (running XP Pro SP2), I find the SSID (using the Windows wireless utility), then I double-click on the network. I enter in my WPA key, just like I always would, and it goes through the process of acquiring a network address and all of that, but as it's doing that, I get a bubble alert in the system tray which says "Windows was unable to find a certificate to log you on to the network (SSID)." The connection seems to still work, though; just I get this message. I have tried a few different laptops, and they get the same message. I have other wireless routers secured with WPA, and I have never gotten that message before using the new Belkin. Out of curiosity, I opened up the second identical Belkin router, applied the same WPA settings, and it seemed to do the exact same thing. I seriously doubt it's a laptop issue, as I have used the same procedure that I have used countless times to connect to WPA-secured networks, and I have also tried this on a few different laptops, with the same result. I searched for this message, and people almost immediately suggest that it means either the router or computer are configured to use a Radius server. Well, neither are, as far as I can tell. In fact, here are the settings for my router: Security Mode: WPA/WPA2-Personal(PSK) Authentication: WPA-PSK Encryption Technique: TKIP Password(PSK): (my WPA key) That doesn't seem to suggest anything different from a typical WPA setup, from what I can tell, yet I still get this weird message. Any thoughts on this? It seems to be router-related, but I'm confused as to why both routers do it. Unless it's something new on the router that I'm missing. And, of course, the network seems to work other than this bubble, but I'm just wondering why it's coming up and how to get rid of it... Thanks!
