The Intel Centrino Wireless N card is on the Dell N4010 and some other laptops. In this case it was the N4010 that a buddy of mine had which gave him the trouble. It’s a compatible card, but needs some nudging to get it to work.
The N4010 also has a software kill button in the form of the F2 key. Bear that in mind when using this machine.
Start by installing rfkill:
sudo apt-get install rfkill
Now check the status of the card:
sudo rfkill list
You should get output similar to the following:
0: dell-wifi: Wireless LAN Soft blocked: yes Hard blocked: no 1: phy0: Wireless LAN Soft blocked: yes Hard blocked: yes
Take a look at dell-wifi‘s Hard blocked status. If it’s yes, your card is disabled via the F2-keys kill function. Hit the F2 key and do…
sudo rfkill list
…again. Your output should now resemble the above.
Now unblock by doing the following:
sudo rfkill unblock all sudo rfkill list
Your output should now look like the following:
0: dell-wifi: Wireless LAN Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no
Your card should now work normally. Now check the connection manager for wireless networks. Reboot and verify you still have connectivity.

Hello,
the command “sudo rfkill list” shows no everywhere, so nothing is blocked.
But the task bar still says “device not ready”

Unfortunately I don’t have much to offer on this. Based on what I did to get this to work on the N4010, your wireless *should* be working. Could you please post the output of
lspci? Thanks!#4 by Dominik on June 16, 2012 - 8:24 pm
