Ubuntu :: Bcm4312 Hardware On / Off Switch
Jun 17, 2010
I realize that a lot of people are having issues with this card, I appologize if another thread is overkill.
I recently made the switch over to ubuntu 10.4 after getting hit with a pretty bad virus on my xp dellmini9. I switched the wlan into off mode in xp, fought with the virus for a month and decided that ubuntu was a better option, but I never turned the wireless back on. I loaded ubuntu from a usb, formating the system in the process leaving me with a healthy system, but no wireless support.
My wired eth0 port is working but wireless still isn't after using alot of the most recent help thread's advice. I was wondering if anyone knows how to turn that kind of thing back on with out gnome's app support for the fn+2 wireless function?

Can the fibre channel switch in the centOS5.3 cluster edition be switched for a regular router or hub?
If so how would one do this? If not why does the switch have to be fibre channel?

I'm relatively new to Ubuntu and Linux OS in general, hope this hasn't already been solved but after trying for 24hrs+ I think it may be time for me to start my own thread (sorry if there is already one). I have been desperately trying to get my Broadcom BCM4312 wireless card to work and after searching about 100 sites and threads I still can't get it going Here are some of the problems Ive been having(I am running Ubuntu 8.04 by the way):
1. Tried installing "Broadcom STA Wireless Driver" under System->Administration->hardware drivers but after install it didn't show any signs of working.
2. I tried getting the Linux driver off the website [URL]... and followed the instructions in the readme to the letter, yet when i am asked to type in one of the final commands: # sudo insmod wl.ko
I get the output: # error inserting 'wl.ko': -1 File exists I have also looked at this website where a guy posts the same problem but no one posted anything back: [URL]...

I have followed the guide posted here: https:[url]....I stuck am at "Under the desktop menu System > Administration > Hardware/Additional Drivers, the STA drivers can be activated for use"I can not navigate to this menu because it does not exist in my build. Is there a way to circumnavigate this?

I had Karmic a while back, but i got rid of it becasue of my Bcm4312 Wireless Card would not recognize the STA driver, or bcm43xx.In that time i learned a bit of command line stuff. anyways now that I have my internet working, I was just wondering What I could do with ubuntu. I am interested in the command line and Programming. Where could I learn more about the 2 subjects?

I've just installed Ubuntu on 2 computers, and I'm new to it. However I'm not new to computers. The problem I'm currently running into on one of the computers is that the wireless will not detect any connections, despite there being many. The computer is a HP Compaq v6203AU using the wireless card Broadcom BCM4312 [14e4:4312]. I've went through dozens of walkthroughs, encountering errors in every single one of them, I've spent 8 hours on this one problem and extremely frustrated. It seem to be a problem with the driver that comes as default, and I'm lost at what to do.
The terminal command "lspci -nn | grep 14e4" returns the following:
03:00.0 Network Controller [0280]: Broadcom Corporation BCM4312 802.11a/b/g [14e4:4312]
ifconfig returns the following:

The computer has no internet access as there is nowhere to connect except through wireless.

I'm flummoxed, guilt-stricken and near my wit's end. The Ubuntu-preloaded Inspiron 1545 I persuaded my girfriend to buy contains the dreaded BCM4312, and nothing I can think of seems to be helping. I've tried various approaches with the STA and B43 drivers. Gad, I feel like I've tried EVERYTHING. Here's where her poor machine's at right now:
Code:
uname -r
2.6.35-24-generic
lspci -v -- omitting output from all the unrelated devices
0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
Subsystem: Dell Wireless 1397 WLAN Mini-Card

I recently switched from 10.04.1 Ubuntu that I had for only about a week, to Ubuntu 10.10 Beta. I switched because I heard that 10.10 comes with firmware right out of the box for BCM4312. I am new with Linux, and Ubuntu, but I do know what some of the commands do and etc. I got 10.10 installed, but the wireless options say "Not connected|Firmware Missing" What do I need to activate the firmware, or install it?

I'm on a Dell Latitude E6500, and I'm switching from Windows 7 to Slackware 13.1; I've never used linux before. I'm trying to set up wireless internet, and it doesn't seem like there's any standard way of doing it for my system. When I run the "lspci -v" command, I find this:
Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
Kernel driver in use: b43-pci-bridge
Kernel modules: ssb
When I run the "lsmod" command, This comes up:

And the wireless doesn't work.

I face in getting my wireless connection work. I am able to establish connection with my router and browse router configuration pages successfully. However, trying to access any other internet address (through browser or ping etc) results in intolerable poor performance (70% to 100% packet loss in ping). Ethernet connection (eth0) works perfectly though. Am furnishing the details below:

I recently bought a Lenovo laptop which comes with a wireless card called Broadcom BCM4312 but in dmesg it says "bcm4315 hybrid wireless controller".
Jockey says the driver is installed, activated and in use. However I don't get any signal (I even moved the laptop to the same room the wireless router is).
I run iwevent and nothing appeared.
I run Kubuntu 10.04, fresh install from a USB stick, latest updates. I replaced knetworkmanager with the network-manager-gnome. network-manager-gnome works fine and I can connect to wired connection with no problem.
Network-manager-gnome says that the wireless is disconnected. What can be done to make the wireless work?

Here are my Specs:
Netbook: HP Mini 210-1012EZ
Network Card: Broadcom Corporation BCM4312 802.11b/g (rev 01
Ubuntu: 10.04 Netbook Remix
CPU: 32Bit
Wired and Wireless Networks work perfectly the only issue is the Mobile Broadband. When I try to setup my Mobile Broadband connection manualy using the Network Connections Manager the device drop-down is grayed out and it doesn't seem like my network card is being recognized as a Mobile Broadband Card. When I had Windows 7 installed and started ubuntu over a USB Drive the connection worked great. I've followed the steps at [URL] too and it all checked out.
I found another idea in a thread here and I've tried that too:
I added the following line to my /etc/modules:
echo b43 | sudo tee -a /etc/modules
I've also tried using the Broadcom STA drivers that ubuntu offers but it doesn't seem to make any difference.

I just installed Ubuntu 11.04 on my Dell Mini 10v and for some reason I just realized that my wired network connection is not working for some reason. And not in windows either. But my wireless works in windows. So I have downloaded the latest Broadcom STA wireless drivers for linux and have tried to follow this tutorial to install it. But when I get to:
make -C /lib/modules/<2.6.xx.xx>/build M=`pwd` clean I can't get it to work. It says:
make: Entering directory '/usr/src/linux-header-2.6.38-8-generic'

I installed OpenSUSE 11.3 with disabled WLAN (otherwise the installation process didn't start). Now the system boots only in Safe Mode with enabled WLAN card (when the WLAN card is disabled it also boots in normal mode though). But even if I try to configure the WLAN card in Safe Mode, the system doesn't boot next time (in Safe Mode) until I add "brokenmodules=ssb" parameter. As I understand after reading this forum I should install a firmware/driver, but there is no install_bcm43xx_firmware script in /usr/sbin directory.

I have installed b43 with the install script and I can see all wireless networks fine, but NetworkManager just keeps asking me for the WPA passphrase, despite it being correct. I tried disabling WPA on the router, but then the connection hangs at "Configuring interface" instad. I also tried with ifup, but I'm not sure I configured everything correctly. I don't get any smarter from the NetworkManager logs, maybe someone else can decipher them? tail -50 when connection doesn't work:
Code:
Apr 18 17:00:11 jan NetworkManager[1291]: <info> Activation (wlan0) Stage 2 of 5 (Device Configure) complete.

I tried to find my solution for hours now but no luck. I'm a medical student and the other day I finally found the time to set up ubuntu for my first time. Everything was working great and I had wireless up and running. However, I tried to set up tethering to my iphone and after that my wireless hasn't been working (I've noticed no other problems). [URL]..Then I used this tutorial [URL].. However, after doing these steps the computer needed to reboot (I actually forget exactly where but I had to reboot in the middle of the second tutorial). After my computer restarted my wireless no longer showed up. By this I mean that wireless network no longer even showed up as an option when I left clicked then connections. However, I did not lose the wireless profile under network connections. So I went to system and noticed that the Broadcom STA driver was no longer active. So I tried to activate again and received this message.

I'm running Kubuntu and Windows on the same machine but when I swap over to Kubuntu I can't get the wireless to work. The lshw command returns network disabled but the machine can see that there is a wlan0 connection.
I've been trying to install the broadcom Linux driver from their site but the instructions fall apart at step 3: cd bnx...version/ ( directory just created by tar). I'm guessing this is because I don't have a Live CD (after almost a week of trying to burn a disc I just broke down and got Wubi) but that doesn't change the fact I have no idea what to do now or if this will even work.
If it makes any difference, the wired connection will also occasionally die mysteriously after about 30-60 minutes of use and refuse to re-activate but work fine when I switch over to Windows or just plug it into the router.
