wifi won't stay connected

I have a HP Pavillion dv6000 with Ubuntu 14.04 LTS and a Broadcom wireless card (BCM4312).

My Ethernet connection is fine. But when the wifi is turned on, it will stay connected for a short time and then disconnect and reconnect again. The wireless card is supposed to use the b43 driver, but it still does not hold the connection.

How can I fix my WiFi problem?

The output from the diagnostic script:

1 Answer

Please do:

sudo apt-get purge bcmwl-kernel-source

the above command will remove the wl driver that is the wrong driver for your device. The next command installs the b43 driver that your device needs.

sudo apt-get install firmware-b43-installer

Reboot

Go into network manager and remove wireless connections then reboot and set the settings to match the screenshots.

Also reboot your router.
