I have searched and tried various web sites solutions to getting wi-f- with my Broadcom 4311 card on Dell D820 Ubuntu/Windows 7

Here is a list of results from terminal

Did you have a look at this?

Hi...

Thanks for posting the information I requested. Another option that might work is just simply open up "Additional Drivers," if you haven't already and install the driver from there. This worked fine on a friend's laptop that had a similar chip.

Regards...

-I kept searching found the following command lines


sudo apt-get update

If you have a b43 card use the command

sudo apt-get install firmware-b43-installer

I had done this before but it never got the B43 = wlan0.

For the wireless card, I don't see a driver listed. Perhaps this is part of the issue?

I went ahead and tried the command

modprobe b43

just to see if anything happened...and my wireless card connected!


UPDATE: I restarted the computer, tried the "modprobe b43" command again (must be run as sudo) and it worked. So things seem to be working, thank you for the help!

Now I have an idea of how to get it working. Thanks for your help and understanding a Newbie frustration.

Now for a shutdown and see if it stays.

Cool, I'm glad you got it to work.

Regards...
