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

[chili555]

on top of that, attempting to run the command:

sudo modprobe w1

returns an error as well stating "FATAL: Module w1 not found." I'm clueless what to do at this point as I've been able to get it to work on my own prior to coming to this forum but with the same issue of my wifi disappearing right after reboot. Really hope you can help me out. Thank you.

First, the name of the module is wl with an L, not w1 with a one. Please try:

sudo modprobe wl

Does your wireless spring to life? If so, let's get it to load automatically on boot:

sudo su
echo wl >> /etc/modules
exit

If there are other warnings or errors, post back; I'll be happy to help.

LoL! Can't believe I didn't notice the l vs 1 haha... Well, afterall, they do look pretty damn the same! Everything seems fine ! sudo modprobe wl functioned with no errors, and also entered your commands to make it automatically run at startup. Wow, you're amazing! Thank you so much! You're the guru!

Glad it's working and thanks for your kind comments.

I am very new to ubuntu and the wireless is not working. I tried the sudo modprobe wl command. But nothing happens after I run it. The terminal just sort of hangs. I have ubuntu 12.04.1 LTS and a very old hp compaq laptop. I am sorry but I have no idea which wireless adapter is in this system.

Next step - blacklisted.

Command: lsmod | grep -e wl -e bcma -e brcmsmac
Output:
brcmsmac 540923 0
mac80211 436493 1 brcmsmac
brcmutil 14675 1 brcmsmac
cfg80211 178877 2 brcmsmac, mac80211
crc8 12781 1 brcmsmac
cordic 12518 1 brcmsmac

Next step
dmesg | grep -e brcm -e wlan
iwconfig

Output
lo no wireless extensions

Next:
rfkill list all

Output:
0: hp-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
1: hp-bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: no

What should be my next steps?

What should be my next steps?

Would you please start your own new thread instead of adding on to this moldy oldy? Please add this information from the terminal:

lspci -nn | grep 0280

Thanks.

In a 160+ post thread going back almost a year, that is my answer.

Hello

chill555, I have the exact same laptop as the person who created this thread, and I followed your steps, however after doing the reinstall of bcmwl-kernel-source I get the following error:

ERROR (dkms apport): kernel package linux-headers-3.5.0-23-generic is not supported
Error! Bad return status for module build on kernel: 3.5.0-23-generic (x86_64)
Consult /var/lib/dkms/bcmwl/5.100.82.38+bdcom/build/make.log for more information.

and when doing the sudo modprobe wl command I get the following error:

FATAL: Module wl not found.

Any idea what the problem could be? All the information matches that of the topic creator, yet for some reason your solution doesn't work for me

[chili555]

ERROR (dkms apport): kernel package linux-headers-3.5.0-23-generic is not supported

Please try this:

sudo apt-get install --reinstall linux-headers-generic
sudo apt-get install --reinstall linux-headers-`uname -r`
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl

Those tickmarks are on the left side of my US keyboard on the same key with ~.

Any improvement?

[Nerph]

Please try this:

sudo apt-get install --reinstall linux-headers-`uname -r`

After doing that part of the commands you advised, I get this error:

Reinstallation of linux-headers-3.5.0-23-generic is not possible, it cannot be downloaded.

Carrying on with the rest, will update my post with how it goes.

edit: It hasn't seemed to work, still the same previous errors, pasted below:

ERROR (dkms apport): kernel package linux-headers-3.5.0-23-generic is not supported
Error! Bad return status for module build on kernel: 3.5.0-23-generic (x86_64)
Consult /var/lib/dkms/bcmwl/5.100.82.38+bdcom/build/make.log for more information.

and

FATAL: Module wl not found.

So no improvements
