Debian Hardware :: Load Firmware For BCM Card With No Internet Connection

Jun 19, 2014

I performed an update that has caused issues with my wireless. Errors relating to wireless firmware missing and consequently no internet connection.

I've been through this before with my 2008 macbook air BCM card whose firmware isn't included in installs. In the past I've manually installed the b43-fwcutter package an extracted some firmware... That doesn't seem to be working here.

I've used [URL]i ... cefirmware to troubleshoot. I have not been able to get b43 or wl to work.

I attempted to install the "firmware-b43-installer_015-14.1_all.deb" package; however it depends on wget to download and install "broadcom-wl-5.100.138.tar.bz2" from

So I manually installed b43-fwcutter and used it to extract the broadcom-wl-5 file referenced....

modprobe wl says wl doesn't exist and modprobe b43 doesn't seem to work.

Code: Select allname-a
Linux air 3.2.0-4-amd64 #1 SMP Debian 3.2.57-3+deb7u2 x86_64 GNU/Linux
lspci -nn
02:00.0 Network controller [0280]: Broadcom Corporation BCM4321 802.11a/b/g/n [14e4:4328] (rev 05)

Other things I've tried:

Code: Select allsudo dpkg -i broadcom-sta-dkms_5.100.82.112-8_all.deb
Setting up broadcom-sta-dkms ( ...
Loading new broadcom-sta- DKMS files...
Building only for 3.2.0-4-amd64
Module build for the currently running kernel was skipped since the
kernel source for this kernel does not seem to be installed.

I tried something from broadcom that produced make errors "/lib/modules/3.2.0-4-amd64/build: No such file or directory"... I think this means I need some kernel development packages, broadcom says:

Code: Select allOn Fedora install 'kernel-devel' (Development Package for building kernel
modules to match the kernel) from the Package Manager (System->
Administration-> Add/Remove Software).

On Ubuntu, you will need headers and tools.  Try these commands:
# apt-get install build-essential linux-headers-generic
# apt-get build-dep linux

I'm having trouble install this stuff without the net and not sure installing generic headers and build-dep outside of apt-get is the way to go... linux-headers-3.2.0-4-amd64_3.2.57-3+deb7u2_amd64.deb has alot of dependencies that would take me a while to find and download.

just did a dual boot or whatever you call it last night)and I can't figure out how to connect to my home wireless internet. I checked in one of the menus, and it says "firmware missing". Does anybody have an idea of what I need to do to fix this? If I haven't been specific enough, please ask for more information. I'm not really sure what to include.

Debian Installation :: How To Force Load Realtek-firmware Driver During Install

Dec 25, 2015

Now, my issue is that I have no access to ethernet in my apartment so I need to rely on wifi for my install. But during the install when it is looking for the network hardware it never sees the TP-Link Dongle and never asks if I wan to load the firmware. I even tried it with the CD image that has the non-free drivers included but it never asks for the drivers. Any other distro, like Linux Mint 7.3, sees the dongle fine.

So is there a way to force load the realtek-firmware drivers during install?

Ubuntu :: Windows Driver Firmware - Error "Wireless Connection (Firmware Missing)"

Jun 4, 2011

after installing Ubuntu Natty Narwhal 11.04, I'm experiencing tons and tons of complications with the wireless Internet connection. I have solved most of them. Now I have only one thing left. When I hit the drop-down menu for wireless connections, it says "Wireless connection (Firmware missing)"

I have installed the driver for my wireless card but what is the firmware? I honestly don't know what it is although it's very basic. I have a Broadcom 43xx as my wireless card (specifically 4306). How do I get the firmware for it? Do I find it in Windows? Also I cannot get b43-fwcutter because I have absolutely to Internet connection on Ubuntu. To post this, I'm using Windows.

Debian Hardware :: Wheezy Doesn't Properly Support Proprietary Firmware For Wireless Card

Mar 17, 2015

I recently installed the XFCE spin of Debian (amd64) on my Lenovo L440. I tried installing it before, but apparently the 3.2 kernel that ships with Wheezy doesn't properly support the proprietary firmware for the wireless card, blah blah. So I wound up using Windows 8.1 for a bit, and then Fedora (boo). Anyway, with the wheezy-backports kernel (3.16.7-ckt4-3~bpo70+1) everything works like a charm. Everything, that is, apart from the sound card — the entire system is completely mute. Well, apart from the system beeper. I searched the forum and found another thread, but that guy was (for some reason) just running dwm — I figured XFCE might feature a more complete sound system. But maybe the output he gave will be useful in my case as well:

Code: Select alleirik@gerhardsen:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1]

I also tried running alsactl init (as root), which doesn't appear to have made any difference.

Debian Hardware :: Radeon X1050 - Is This Card Supported In Squeeze By Either The Non-free Firmware Or The Proprietary Driver

Jan 13, 2011

Is this card supported in Squeeze by either the non-free firmware or the proprietary driver? I just got one to stick into an older box that will be going to a college girl that wants the 3D desktop in KDE. The built-in video was a joke and wouldn't even work without compositing. It was one of those crappy, non-standard pieces of crap known as a "Unichrome" (not the pro).

Ubuntu :: Yahoo Mail Won't Load / Getting An Error Page (as If There Was No Internet Connection)?

Jul 3, 2010

I just downloaded and installed Ubuntu a few days ago (on my Windows Vista Laptop), played around with it, did some trouble shooting (got my wifi card working!)... and am generally enjoying it.However, I am having issues loading my Yahoo Mail. I am using the newest version of Opera (which I also run on windows), but have tried Firefox as well. I am having absolutely no issues with Yahoo mail when I use Windows (in Opera, firefox, chrome, and IE), but can not get it to load at all with Ubuntu. Basically I can get to the Yahoo home page no problem, and can access any of the links etc., except for Mail. When I click it, I just get an error page (as if there was no Internet connection). I have not had problems with any other sites.I'm thinking its some kind of scripting/application conflict, but like I said this whole Linux thing is brand new to me. Have only ever really used Windows in the past.I'm hoping to get these minor issues hashed out, and eventually just drop Windows out of my reality.

Ubuntu Networking :: Broadcom WLAN - Connection Refuses To Load Anything Off The Internet / Local Network

Jun 6, 2010

I dual boot windows xp and ubuntu 10.04 LTS and the wireless card works perfectly fine in xp so I know its not a hardware/network issue. In ubuntu, it detects wireless networks, will connect to network and work for about 20 seconds.


and it continues on after this alternating between a normal 20ms and high ping over 200ms. The connection refuses to load anything off the internet/local network.

Ubuntu Networking :: Sharing An Internet Connection Through A Wifi Card

Jan 30, 2011

Im living in a student-city where we get one internet-cable in the wall each, if we need more we are told to use a switch. But, since ive got some tech that depends on wifi, I was wondering if its possible to setup my ubuntu to work like a sort of wifi-switch?

Basically, Im not allowed to set up anything that resembles a router..(so no dhcp) all i need is what a switch would do, only wireless and wpa/wep would be very nice

Atm ive got my cabled network plugged into my onboard ethernet-port, and ive got a d-link DWA-556 (Atheros AR5008 I think) wifi card that i wanted to use to share my connection. is this doable?

General :: Slackware Internet Connection W/ Intel 6050 Link Wifi/wimax Card

Feb 20, 2011

I'm a Linux newbie. Used to use Ubuntu, but I switched to Slackware because I want to learn how Linux works better.

On my Samsung qx410 laptop, I can't connect to the internet. I went to the System Settings -> Network Settings and all the tabs there, but it wouldn't detect any connection, wireless nor wired.

I noticed that the kernel of Slackware 13.1 is out of date, so I tried compiling a newer one, but I couldn't get that to work.

I tried downloading this file: iwlwifi-6050-ucode- but even after reading the readme, I had no clue how to go about installing it or even whether it was the right thing to install in the first place.

How can I get my internet working?

Hardware :: SD Card - Debian Sid - Mmcblk Device Dies Under A Heavy Load

Feb 24, 2010

Is there a way to switch a internal card slot from /dev/mmcblk0** to /dev/sd** ? I'm backing up (via rsync) an ebook directory (1.9gb) to sd card and get massive i/o errors, card turning read-only,etc. This is via a built-in slot on a toshiba laptop. When I use a card reader, the card attaches to /dev/sdd1 and all is fine.

This is a new Sid install. The laptop's card slot worked fine under Ubuntu 9.04 and still works if the amounts of data are small. All I can figure is that the mmcblk device dies under a heavy load...

Ubuntu :: Connection - Load A Website Taking To Long To Respond And Sometimes Doesn't Load

Oct 2, 2010

When i open one of the web browsers i use and try to load a web site it's taking to long to respond and sometimes it doesnt load the website at all. I have tried with firefox,epiphany,opera with all the same results. I am sure that this is not a problem with my internet connection because i don't have these problems with windows.Also the network manager connection settings are correct

I also tried choosing the old kernel( to boot from but no success.The problem is the same as if i am using the kernel. The strange thing is that i can download packages from synaptic with full speed. Last think.I have recently downloaded the recommended updates from the update manager but i don't remember what are the things that where updated.

Debian :: No Internet Connection / Network

Sep 26, 2010

I am working on a cross-platform application for Linux ,Apple and Windows, so I have a full tower system with four SATA hard drives that be selected with a switch, so that I can change drives and operating systems at will. -sort of makes me a jack of linux systems, but master of none.It's important to mention this, because it shows the strangeness of the problem as it is isolated to Debian* systems.

So where does debian/ubuntu get it's information to establish a network connection?How do I rectify the problem? I can hardly blame the hardware (RTL8111B), because the problem is isolated to Debian systems.
