I have Ubuntu 11.10 installed today and trying to connect to wireless but its not working. It has been working correctly on my Windows 7. i am pretty new to Ubuntu. I tried suggestions listed in this forum but nothing seems to be working for wireless.

It shows wireless card listed when I do- sudo lshw -C network: It displays wireless interface as BCM4313.

my laptop- Dell Inspiron 4010 Ubuntu- 11.10

Any suggestions?

It works when I connect LAN cable to same modem.

Connect your PC to the internet via LAN. Open terminal and run this command:

sudo apt-get install b43-fwcutter

Reboot and Wifi should work.


Have you tried installing proprietary drivers? To do this, you need to:

  1. Connect to the internet with a LAN connection
  2. Check if any proprietary drivers are available
    • via System Settings, or:
    • by running jockey-gtk in a terminal
  3. Restart to enable the new drivers

Other tips:

  • Make the network public (visible SSID) and check if it's visible in Ubuntu
  • Try connecting to any other WLAN, to check if there might be some problem with the network configuration
