Please Help- No Wireless detected- Broadcom

[Novo]

Hi all,

I am new to linux, I have researched the last few hours to my problem and don't seem to be getting anywhere. I've tried downloading b43 and the STA drivers... Really stuck with this, any help would be much appreciated According to driver manager i'm using bcmlw-kernel-souce as the alternative driver... It doesn't work?!? Thanks again for any input

This chipset should run fine on the bcmwl-kernel-source (the "wl"). What's the output of this command:

Code: Select all

sudo rfkill list all

Press Enter. Type your password when asked; this will remain entirely invisible, not even dots will show, this is normal.

Have you used the additional driver tool to see if it offers you a driver for your card?
if not go to system menu and try that first.

also can you list the output of

• lsmod

Hi guys,

I seem to have it working- I installed wicd network manager. It seems inconsistent though, it picked up the wireless networks but kept saying I had a bad password but on my fifth attempt it worked?!

So I'm happy.

Thank you for your time

glad is sort of working for you.
the inconsistency could still be that you have the wrong driver installed, list the ouput of

Code: Select all

lsmod

and we will see.
