Installed new Ubuntu / Pinguy os and not able to use wireless / wlan ? Here is the fix.
This problem is well known and seen many times when we update packages or when we remove windows and install Linux.
First check that you have all required drivers install. Generally Broadcom STA is widely used for wireless LAN / wlan so lets check it safely without installing or removing anything.
Go to System tools > Ubuntu Software Center
and search for broadcom and see something like this.
If drivers are not installed install them and restart your PC.
But if drivers are already installed but you are facing this problem then follow following steps.
open terminal and type
Enter your password. then
sudo rfkill unblock all rfkill list
See output like this
$ rfkill list 0: dell-wifi: Wireless LAN Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no
Now check for the same error ie. wireless is disabled by hardware switch
Probably your problem is fixed. Finally Enjoy Wireless !!
Now lets add this as a start up application so that when you restart your PC it will automatically unblock all wLan rules.
open – preferences >>Startup applications’ preferences and click on add and add new command as shown bellow.
Note: This is the temporary fix and I recommend that you should stay tuned with official broadcom website for driver updates. I is seen that when you install Ubuntu (Linux) alongside Windows (Dual Boot) this hardware driver works properly.
Feel free to post questions and suggestions.
