I installed Ubuntu 12.04 Precise on a Lenovo Z570, but the WiFi isn't working. I noticed that the WiFi Network is UNCLAIMED using the command sudo lshw -C network. Anybody can help?

WiFi card: Intel Corporation Centrino Wireless-N 1000

Here are my system info:

salim@ss-host:~$ uname -a
Linux ss-host 3.5.0-37-generic #58-Ubuntu SMP Mon Jul 8 22:10:28 UTC 2013 i686 i686  i386 GNU/Linux

dmesg | grep iwl returns nothing.

salim@ss-host:~$ sudo lshw -C network

  • Hi Alaa, I tried the to copy the compiled driver to /lib/firmware but it didn't works, I deprecated such information since I found it not useful, and could mislead the user. Thanks for your support.

the Wifi issue has been fixed, once I have updated my Ubuntu machine, and the Wifi/blue-tooth are detected, etc. Also, the Wifi hardware it's not anymore flagged as UNCLAIMED, it's recognized now using the (lshw -C Network).

Best,
