Hi,
My wifi connection has been working flawlessly for 2 years running first ubuntu 11.04 and gradually upgrading to 12.04. A few minutes 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 (3) 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.
Also I have reinstalled my laptop and during installation the wifi is present as wlan0 but after upgrade its changed to eth1.
Any ideas on what the problem might be? Tips on how to debug it?
Thank you for your time and help.

I solved this problem but this is not what I wanted.
Fail - I have reinstalled Ubuntu using the ISO (with selected 3rd party drivers) and during installation a wireless card is present as wlan0 but after upgrade its changed to eth1 and a network connection is lost.
Ok - I have reinstalled Ubuntu using the ISO and then upgraded using a wired network instead of wireless, also the 3rd party drivers were not selected. After the reboot, OS is able to connect to AP. At this moment everything is working fine and a wireless card is present as wlan0.
