Hey. I just formatted a Dell n5010 and installed Ubuntu 10.10. Now,when i try to access the Internet it doesn't find the available networks.

Informations about it:

  • My network is set to broadcast SSID;
  • Already typed lspci, and it doesnt returns my wireless card;
  • Tried installing windows drivers from fabricant cd usind diswrapper, but it says it cant complete the installation because it cant find some "Device" folder;

I don't know what else to do, I switch the wireless button on/off and it just can't see any wireless connection, includin mine.

  • did you activate the restricted driver ? What does Administration > Additional Drivers show ? You seem to have broadcom card Feb 23, 2011 at 4:22
  • the Additional Drivers show an alert box when start "Failed to Download their packages, please check the status of your network. Many drivers are not available". And then with the Additional Drives opened, it shows no drivers and its written "No proprietary drivers in use on the system".

  • go to synaptic and install bcmwl-kernel-source. try removing ndiswrapper if you are using it. If bcmwl doesnot work try b43-fwcutter or different b43-firmware-installer. It should work most probably. :) Follow this link help.ubuntu.com/community/WifiDocs/Driver/bcm43xx Feb 23, 2011 at 11:54
  • From Software Sources, enable all the repositories as well.

If you are not connected to the internet, mount your Ubuntu CD or USB, and try to install from Additional Drivers or execute this command in the Terminal:

sudo jockey-text -a

or

sudo apt-get install firmware-b43-installer

The first command does the same thing as Additional Drivers, and should no return any output once it's completed successfully. The second command directly pulls the driver package for your Broadcom chipset. Following these steps with internet connection will work as well.
