So I recently bought a Asus u56e-bal7 notebook computer. It came with the following specs: Intel core i5 processor 6.00 GB RAM Intel Centrino Wireless-N 6150 After installing Ubuntu 11.10 I wanted to get some applications for myself and begin using my computer. The main problem i'm having is connecting to my wireless network. When I click on the icon to connect to wireless networks, it shows me the networks available but I just can't connect. I do not get any error messages, but every couple of minutes of trying waiting for it to connect, it tells me to retype my password for my network. I am fairly new to linux-based operating systems so if you have a solution try to dumb it down please. Thanks!

Can you open up a terminal and type in tail -f /var/log/messages, hit enter a few times so you get a nice big gap of blank, then try to connect to the network. After it fails, hit ctrl+c in the terminal to end that command, and paste whatever text showed up in the terminal into your question. It might help debug. – maco Feb 10 '12 at 22:36
