I have finally got the Broadcom wifi network card to work--Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01). This article was very helpful. However, every time I boot the computer, I have to go into terminal and enter the following commands in order to get the wifi working:

sudo modprobe -r b43 ssb wl
sudo modprobe wl

How can I connect to the wifi automatically when I boot my computer without having to manually enter the commands above manually every time I boot?

Thank you.

    Do you mean wifi network card, not router? What is your Ubuntu version?

You have this problem, because you installed b43 driver.

It can be fixed by

 sudo apt-get install --reinstall bcmwl-kernel-source

This package will blacklist b43 permanently.

  • Thanks for the suggestion! I entered the command you suggested in Terminal, but after reboot still the same issue. I have to manually enter the two command lines above in order to get the wifi to work.
