Broadcom BCM4312 Not Working

Question

I have a HP MINI 210-1010NR and just installed Ubuntu 11.04 and I can't get my wireless to work. I have checked through multiple Q&A's throughout this FAQ and tried them all. When I go over the wireless thing at the top it says "Wireless Networks device not ready (firmware missing)."

Okay, now here is my

lspci -vvnn | grep 14e4

02:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g 
LP-PHY [14e4:4315] (rev 01)

Also, when I try to open additional drivers it says that "Downloading package indexes failed, please check your network status." I have no means of other Internet Access.

I tried to do the ndisgtk things and attempted to install all of the things that were in the photo but I don't know where to find them.

Answer 1

You need to have internet for jockey to install wireless driver so make sure you have wired internet first.

If You want to go manual route try:

sudo apt-get install bcmwl-kernel-source

And see if your wireless works or not else try:

sudo apt-get purge bcmwl-kernel-source && sudo apt-get install firmware-b43-installer

If the first process doesnot work.

Answer 2

I have the same problem with same driver. This is what I do to install the correct drivers.

1st, install Synaptic Package Manager from the USC, Ubuntu Software Center. It has always been default in Ubuntu until 11.10, but it still works great. Open Synaptic and search for B43. This is what you will get.

Notice the choices available and the drivers I downloaded. If you have a question you can click on the item and a brief description will pop up. It works on my dv5000 series, I just did a fresh install last night. Good Luck!

Answer 3

git clone git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git

cd linux-firmware

sudo cp -a brcm /lib/firmware

sudo modprobe -r brcm80211 && sudo modprobe brcm80211

profit (:

Answer 4

This solution encompasses many of the other suggestions you have received so far.

Try connecting to a wired connection (preferably do this somewhere with a wired connection (for the downloads) and a wireless network (to test the drivers)), and following the instructions in this wiki of the Ubuntu Community Documentation. Thus old, this document is still usable.

I have that same network card and both the STA and the B43 drivers work for me. Good luck!

Wireless trouble out-of-the-box

After several Trouble shootings,

Solution:

USC: Synaptic Package installer

-Opened Package Installer>search "b43" -Installed 3 packages: firmware-b43-lpphy-installer b43-fwcutter firmware-b43legacy-installer

Restart.

worked

Answer 6

In fact the firmware-b43-lpphy-installer and/or b43-fwcutter is all you need.

firmware-b43-installer and firmware-b43legacy-installer do not even install properly on 4312 hardware.

The STA driver (aka bcmwl) may work but not always, so I recommend firmware-b43-lpphy-installer.

Answer 7

Try ndiswrapper (you most likely have to install it, so sudo apt-get install ndisgtk). This program allows you to use windows drivers for wifi under linux so you have to just download appropriate driver from here and use it with ndiswrapper (it has a gui which you can start by ndisgtk in terminal). The interface is quite simple, there should be no problems with that.

Answer 8

There's no need for ndiswrapper and Windows drivers, because the Linux driver already exists,

• if you see no broadcom wireless device name, uninstall driver, restart computer, install driver and restart again until "firmware missing" message appears with wifi device name under wireless icon after clicking on it (gnome).
• If you haven't it, you must install a synaptic package manager from Ubuntu software center
• search "bcm" inside synaptic package manager
• mark for installation "b43-fwcutter", "firmware-b43-installer", "firmware-b43legacy-installer" and apply, no restart needed. Your Wi-Fi led turns on immediately.
