I have an ASUS U56E laptop with an Intel Centrino Wireless-n 6150 chip.
Ever since I updated to Ubuntu 11.10, I have been unable to connect to any wireless network. In the network manager tab, I see all of the wireless networks nearby, but whenever I try to connect to one, it appears to keep loading without ever connecting. Password-protected networks ask for the password every 30 seconds without connecting.
Wired connections work fine.
The output of iwconfig is:
I was previously able to avoid this problem by booting the 2.6.38 Linux kernel instead of the latest kernel (indicating it is a problem with the kernel?) However, with new updates, the old kernel fails to load Unity and thus is unusable.
lo no wireless extensions.
eth0 no wireless extensions.
wlan0 IEEE 802.11bgn ESSID:"Wireless network to which I am trying to connect"

How can this problem be resolved? Thanks.
