Intel Centrino Wireless N 1000 doesn't work on a Lenovo Z560
- by Timetraveler
I upgraded my Ubuntu 11.04 to 11.10 and my Wifi has stopped working. I have a Lenovo Z560 that has Intel centrino wireless-N 1000. I have searched various threads having similar problems for a solution and have no success. The wlan0 is not even showing up in rfkill.
Please help me find a solution.
I am giving below the output of various debug commands. Thanks in advance.
