So I've been dual booting eOS with windows 7 for about 3 weeks now and I've absolutely loved it. I haven't had any problems until today. For some reason I cannot connect to my wireless router. I went out of town for a week and when I came back, eOS wouldn't establish a connection. My router is recognized and the following dialog pops up every 2 mins or so:
======================================================================= Authentication required by wireless network Password or encryption keys are required to access the wireless network 'abc1234'. Password: ********* Cancel / OK =======================================================================
I repeatedly hit ok and after 5 or so pop ups eOS just disconnects. I've double-checked that I'm entering the correct password but it never connects. I've reset my router, switched my wireless card off and back on, and logged into my router to see if there were any suspicious changes. The weird thing is that I can connect on Windows 7 just fine. I'm running the 64-bit eOS on a Thinkpad T430. Any suggestions?
Edit: I'm able to connect to a mobile hotspot using my phone so I think it may be more related to the router configuration as Paulo pointed out.
