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

Hi, I'm new to linux, I've only been using it for a short period of time. I just upgraded to Ubuntu 12.04, and stupidly didn't check if everything would work before upgrading. I am now stuck without working wifi. I'm not positive what my wireless card is, but the Broadcom STA wireless drivers seemed to work without any problems. My laptop is an acer aspire 5750G, running Ubuntu 12.04. When I go into the additional drivers section of system settings, the drivers show up, but when i click activate, it comes up with this error:

"Sorry, installation of this driver failed.

Please have a look at the log file for details: /var/log/jockey.log"

I have no clue what this means. Help me Ubuntu forums, you're my only hope!

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:

Code:

---

lspci -nn | grep 0280

---

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

here's what i got

03:00.0 Network controller [0280]: Broadcom Corporation BCM43227 802.11b/g/n [14e4:4358]

Perfect!

With a temporary ethernet connection, please do:

Code:

---

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

---

After it's done, do:

Code:

---

sudo modprobe wl

---

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

Thank You chili555, I have a Samsung Core i5 portable pc, and I recently upgraded to 12.04 from 11.10, and had this exact same problem. This pc also had a similar situation with/Network controller [0280]: Broadcom Corporation BCM43227 802.11b/g/n. U opened up a terminal and used your fix as well, and BINGO, it worked. Thanks! :)

Glad it's working.

Note to searchers: If your pci.id is not 14e4:4358, then this may not work for you. Start a new thread or search for your specific pci.id.

Used this fix for pci.id [14e4:4727] and it worked flawlessly.
