BCM4312 802.11b/g LP-PHY (rev 01)

I’m a complete Ubuntu novice and have installed Chromixium on to my old Dell Mini 10 netbook. It’s given it a new lease of life and I’m really enjoying getting to know a new OS.

However, I can’t get the wireless adaptor working. I’ve read the pinned post and followed the steps but no joy. Could anyone assist? I believe that for the adaptor I should be using «sudo apt-get install firmware-b43-lpphy-installer» but I get this back

Package firmware-b43-lpphy-installer is not available, but is referred to by another package.This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
firmware-b43-installer

However when I do install that package, my wireless still doesn’t work. Am i missing something?

download this package and save it in «Downloads»:

sudo tar xvf ~/Downloads/2480236-Broadcom_Firmware.tar.gz -C /lib/firmware/

Hi there, thanks for helping out.

I’ve tried that but still no joy. I had wireless while the netbook used XP so I don’t think it’s faulty

dont really want to try ddm after reading all the posts on it.seems like it doesnt do much since i know the driver i just cant get it installed using additional driver.was wondering if i had to do a dpkg —configure -a in terminal to get it working?but anyhow im going with opensuse 12.2 kde for the time being.actually kinda liking its speed.would like to see a working method though on this post.thanks

[SOLVED] How to get the Broadcom BCM4312 802.11b/g LP-PHY wireless/WLAN/WiFi adapter working on Ubuntu 14.04 Trusty Tahr or LinuxMint 17 Qiana — (Tested on a Dell Studio 1435 Laptop)

Note: I did this for a friend’s Dell Studio 1435 Laptop, while installing the latest LinuxMint 17 Qiana Mate Edition. This should work on Ubuntu / LinuxMint for any machine which has a Broadcom BCM4312 wifi (802.11b/g) adapter.

You can make sure that you have the correct device mentioned here, by typing in the following command in the Terminal:

It should show something like this:

0b:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev01)

If this has been confirmed, you can proceed with the following:

Solution:

Run the following commands in Terminal:

sudo apt-get update sudo apt-get purge bcmwl-kernel-source sudo apt-get install linux-firmware-nonfree

Now reboot your system, and there you should see your WiFi working fine!

Let me know using the Comment box below, if you found this useful, or if this didn’t work quite as expected — I’ll try my best to help you out.

Thank you!

Recently acquired a laptop running lubuntu and wireless was not working, but I plugged in the hardline and did the command prompts and it worked perfectly!

Baffled

This is a Dell 1545. I have Linux Mint Rebecca installed. On another hard drive in this same computer, I also have Linux Mint Rebecca, and it has worked for nearly two years.

I wanted to make a clean baseline install to another disk, so I swapped them. The new install will not load the drivers for the BCM 4312. lspci finds the card, no problem, and I ran

sudo apt-get update
sudo apt-get install firmware-b43-installer

This ran without error, but the driver still didn’t load and ifconfig does not show the wireless adapter.

Then I ran the commands you recommend and rebooted. Still no wireless. Not much luck in an Internet search, either; they all seem to say the same thing, and I have already done all that.

Best regards,

WIFI rfkill switches on Lenova S10 — Linux Mint KDE 17.2 32-bit

Thank you for this very helpful posting. I also found some other things that might be helpful.

I am running Linux Mint KDE 17.2 (32-bit) on Lenova S10 netbook. I had much trouble getting the built in WiFi working, but it turned out to be something to fix, involving a couple switches and completely turning off the computer.
On some laptop there are switches to control the wifi adapter. One type of switch is called «Hard» WiFi switch which is a hardware switch which is not usually part of the regular keyboard. I have a Lenova S10 netbook with a green hardware wifi switch located near the power switch above the keyboard. This particular laptop also has a function key (F5) to contol the wifi as well. Both switches have to be «on» for the wifi to function ! You can see the state of these switches by typing «rfkill list» in the console (terminal). It will list something like (with other stuff):

2: brcmwl-0: Wireless LAN
Soft blocked: no
Hard blocked: yes

In the above case the hardware wifi switch has turned off the wifi.
Turn turn it back on you can press the hardware wifi switch and then type «rfkill list» in the console again. It should be unblocked.

Also there is utility you run from the console called «mintwifi». That might be helpful. See:

Another strange thing that happened, as reported by others, was that I found that even though I had the wifi turned on according the «rfkill list» command, I had to shut down the computer, remove the battery, try turning it on without the battery to discharge the capacitors, then reinsert the battery. When I turned the computer on the wifi appeared on the network manager on the system tray. See:
