Weird WiFi connectivity issue
 

Cannot connect to corporate WiFi, even though could do it without any problems in the nearest past. Also a coworker of mine can do this from his 770 with 2008 installed. Network is with WEP protection, and it uses key 2. There is one weirdness there - there are two networks with the same SSID - another one is displayed as a locked lock with 3 keys inside (WPA?) . When I try to connect, wifi icon blinks several times and then shows up a message window with a message similar to 'Error connecting to the network. Repeat?'. Are there any logs I can check? Can I debug it somehow?
Forgot to mention that I have N800 with Diablo.
