I installed a fresh install of Ubuntu 12.10 and this is my first Ubuntu install. I have a Dell Inspiron 6400 and my wifi is turned off and cant seem to switch it on. I searched a lot on it but can only find answers for Ubuntu 12.04 :( can someone help me please? Thanks in advance
I have the same problem and this was printed:
lo no wireless extensions. eth0 no wireless extensions.
The main problem was that I didn't check the "Install third party stuff" when my Ubuntu was installing. So I ran the following command:
Went to Additional Drivers tab and checked to use any proprietary driver I want.
I had the same issue and this is what worked for me:
sudo apt-get remove bcmwl-kernel-source sudo apt-get purge bcmwl-kernel-source sudo apt-get install linux-firmware-nonfree
Welcome to Ubuntu world. question you asked has a broader concept, i may require few answers from you :
have you checked id your WIFI LED is glowing (or some other mechanism that lets you know that your WIFI is on).
reply with what you see as a result of iwconfig on commandline.
Meanwhile you can try :
- Disable the non supported driver.
- Go to Synaptic and install b43-fwcutter and firmware-b43-installer.
PLUG IN ETHERNET CABLE
run these commands in terminal
sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source sudo apt-get update sudo apt-get install b43-fwcutter firmware-b43-installer
THEN UNPLUG ETHERNET AND REBOOT
