Broadcom STA Wireless drivers not working on Acer aspire 5750G, Ubuntu 12.04

[newbiedev]

Please download the file I've attached and transfer it on a USB drive or similar. Drag and drop it to the desktop of the Dell. Right-click it and select Extract Here. Now open a terminal and do:

sudo mkdir /lib/firmware/b43
sudo cp Desktop/b43/*  /lib/firmware/b43
sudo modprobe -r b43
sudo modprobe b43

Is it working now?

Thanks you very much, this worked...Oh I tried it on the 12.04 and it worked. Do I need to this on every boot or its permanent?

It's permanent. You should be all set, but if you have a problem, please post back and we'll be glad to help you.

A known issue is that jockey; also known as Additional Drivers, suggests the wrong driver for a few Broadcom cards. Let's find out what you have and solve it. Please open a terminal and run and post:

lspci -nn | grep 0280

The pipe symbol | is on the right side of my US keyboard on the same key with \. Thanks.

I have the same problem, I ran that code above and got Broadcom Corporation BCM4313 802.11b/g/n Wirelesss LAN Controller [14e4:4727] (rev01).

By the way, how do you copy and paste in Ubuntu? Ctrl C and Ctrl V do not seem to have any effect. Nor do I see a menu bar to select copy or paste in the terminal.

Please start a new thread; this one is getting old.

You simply highlight the text and right-click then select Copy. Please see attached.

Right click won't work in Ubuntu on my mousepad. I see no settings to change in Mousepad under System settings that could make it work.

What sort of device is it? How do you paste then?

Perfect!

With a temporary ethernet connection, please do:

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

After it's done, do:

sudo modprobe wl

If there is no error or warning, your wireless should be working.

Thanks!
