I'm running a Sony VAIO VGN-CR410E, and recently moved it to Ubuntu from Windows 7. Both my home and work networks (which I maintain) run WPA/WPA2-PSK authentication for security.
My wireless network card (intel 4965AGN) will not connect to them unless I am in the same room (kind of defeats the purpose of wireless). The PC is 4 years old and the routers are brand new (last month or so). Had no problems with it with Win7, but Ubuntu just doesn't like the networks. As an IT manager, my laptop needs to work, so any help is appreciated.
If this is a duplicate, please let me know of what. I've spent hours searching and nothing has worked. Thanks for your help. (This is my first experience fully relying on Ubuntu). I can see the networks and attempt connection, but it fails authentication. Let me know of any code you need.
