Can’t connect to any wireless connection after updating
My wifi connection has been working flawlessly for 2 years running first ubuntu 11.04 and gradually upgrading to 12.04. A few days ago the connection to my router suddenly stopped working after a restart (it had been connected right up until the restart). The network icon on top shows that it is trying to connect and after a while it stops and tells me I am disconnected. All other devices (6-7 or so) connected to the router continue to access as usual so I do not think it has anything to do with the router itself. Also I found out that I have no problem connecting to the hotspot of my cell phone. Both on my cell and on the router I have WPA-PSK, but I guess that they would be using different standards (n on router versus b/g when using phone hotspot?).
Any ideas on what the problem might be? Tips on how to debug it? I did install the latest upgrades through synaptic prior to restarting, can I have upgraded to a broken driver or something?
