Ubuntu Networking :: Broadcom B43 Wont Turn On/ Recognize Wireless Signals?
Nov 21, 2010
So I just loaded ubuntu 10.10....and it works great...except for my wirelessi've got a broadcom b43 ...i went into system, administration, download additional drivers and downloaded/authenticated a b43 driver, but my machine (hp dv4405) does not recognize any wireless signals. The wireless light on my computer doesnt turn on (there's a button to turn it on and off) anyways...it's annoying. I guess broadcom recently released some open source drivers, but I'm having trouble sorting through all the info

I'm completely new to openSUSE and when I installed it, my wireless card isn't apparently found. The light on the keyboard doesn't turn on signaling there is a wireless card. I should have also said I'm using the KDE thing, not the GNOME.

I have an HP mini 110 with Fedora 11 install. I installed the broadcom-wl and wl-kmod from yum but still no wireless. First I can't get the broadcom card to turn on using the slide switch on the front of the computer. The device is inactive in the network configuration-devices window. The card is not in the network configuration hardware window. When I try to add it manually, there is no entry for the card in the drop down list. I am new to Fedora but have used linux for years. Unfortunately this is my first attempt at wireless networking.
The posts and google stuff doesn't say much more than "yum install broadcom-wl" Can anyone point me into the right direction? I have a feeling I am missing something very simple, because this computer dual boots Linux Mint and wireless works flawlessly.

I've got the b43 driver and firmware installed, and the system comes up fine, but the max throughput on the wlan0 is about 100Kb/s. My laptop and iwl do about 2.5Mbps from the same location in the house. The signal is plenty strong:
wlan0
IEEE 802.11bg ESSID:"sar2"
Mode: Managed Frequency:2.422 GHz Access Point: 00:23:69:22:5C:00
Bit Rate=36 Mb/s Tx-Power=20 dBm
Retry min limit:7 RTS thr:off Fragment thr:off
Power Management:off
Link Quality=61/70 Signal level=-49 dBm Noise level=-57 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
Is this expected from the b43 driver and a bcm4318? I was hoping for much better throughput. Also, I tried the broadcom-wl driver, but it doesn't seem to recognize the card. It looks like it's not supported from their site, only the 4311,12,21,22 were listed, although I see posts where other people claim they are using it with a 4318?

I am running openSuse 11.1 64 bit on my hp pavilion dv6458se; and am unable to get my Broadcom wireless card to work.
i tried reading a few forums, but they all start when 'lspci' recognizes the card.
My problem is that 'lspci' does not show any 'Broadcom' card.
I have given below the output of 'lspci' for your reference.

barley got it today in fact, have my laptop dual booted running Win7 and Ubuntu 10.04. I haven't worked with the terminal at all so i have no idea what I'm doing with this. I'm having a problem connecting to the wireless Internet. It has theicon at the top but doesn't recognize any signals. Works fine using land line though. My laptop has the wifi on/off button on it but that doesn't seem to be doing anything

I can't pick up any wireless signals while running Ubuntu 10.04, but while running Windows 7, I pick them up. I have the feeling it's because of a missing driver, could anyone help me solve this issue?

I had windows and 8.10 earlier and now have single boot 10.04 !
1.) I can see wireless networks only after I am connected to the router through wired ! I guess its some thing to do with me activating ifup and ifdown, when my wired connection stopped working as i was trying to install wireless drivers.
2.) Even when I see wireless networks, i cannot connect to any of them.
I tried various things for a whole day trying to fix it and i doubt if i screwed up some thing that was running good.

just switched from Windows Vista to Ubuntu 10.10 on my Toshiba laptop and I'm loving it, except for some wireless connection problems. About 70% of the time, my computer is unable to find any wireless signals whatsoever, despite being right next to the router. When it does find the signal it connects fine and runs great, but most of the time it doesn't show any signals at all. I can't find any pattern to when it does or doesn't find the signal. My result for the "sudo lshw -C network"

I've been running Karmic since it was officially released on my Dell Studio 17 (specs are in my signature) with a Broadcom wireless half mini wireless card.hen I installed Karmic, it gave me the option to install proprietary drivers for my video card as well as 2 Broadcom drivers, STA and one of the BC43 drivers. I installed all of these, and the only problems I had were with the audio. I spent a few days troubleshooting the audio and finally got PulseAudio set up for my card.
Almost 3 months later, I was making use of my wireless network at home, as I had done plenty of times over the previous 3 months, when I closed the lid (thus putting the computer into sleep mode) and took it to the hospital to stay with my fiancé¥ after her surgery. When I got to the hospital, I couldn't get their network to show up. Network Manager didn't even recognize the network. We had also brought my fianc饧s laptop (same machine with a slightly less powerful CPU and only 4 GB of RAM). She is running Windows 7, which detected the hospital's network with no problems.After trying to ad-hoc the hospital network with no success, I finally just gave up and played Sudoku and toyed with some graphics stuff in GIMP until we came home. Upon returning home, however, I was shocked that my card didn't even detect our home network.
I have been unsuccessful for the past 3 days in getting Network Manager to identify our wireless network. The wired network connects without issue and I am able to make use of a USB Belkin adapter, which identifies all 7 of the various wireless networks in my neighborhood, including our home network.While I would be able to simply carry my Belkin adapter with me in order to make use of wireless networks, I would really like to solve this problem with my Broadcom adapter. I've gone through the Ubuntu Wireless Network Troubleshooting guide, but I still can't get it to workOutput of lshw -C network:

I am running FC13 on a Compaq Presario 2100 using a Broadcom BCM4306. I was able to get it running thanks to Fedora Unity Project. But It's a very unstable connection. I don't know what settings to adjust or enable or disable. It's not my router, this is the only wireless connection in the house that I have trouble with.

After some serious trouble with Plasma, I decided to re-install 9.10. When booting up, I noticed that the wireless indicator light stayed on orange which usually means that the driver is not loaded.
I have a Broadcom 4312 in a HP Pavilion dv6. I checked the repository but no driver shows up. I seem to remember that it used to be there. Or am I mistaken and do I need to install the vendor driver from the Broadcom site?
I've added the output of lspci and dmesg | gre b43

I've got a Dell Inspiron mini 10 that has the Broadcom 4322 wireless chipset in it. I have NEVER got this thing to work satisfactorily despite the numerous tutorials online about getting this damned card to work. I thought everything would finally be fixed with 10.04 but no luck at all. I've tried the b43 diver (which isn't supposed to support the 4322) with no luck.
I also tried the restricted STA driver, which seems like it will work as it identifies networks and even connects to them! However, the speed is excruciatingly slow and connections drop like flies. This netbook is actually a friends that I convinced to let me put Ubuntu on and have them try it out, but they are most surely not going to be impressed if the wireless never works.

with some troubles, i finally installed the broadcom wireless driver. it says it's installed and activated, the blue light on the laptop is on saying the wireless is activated, but for the life of me i can't figure out how to make it connect. the only network connection icon i have is the wired one. it's not showing the wireless, or available wireless signals or whatever.
this is my first time using wireless with linux (thought i've been using linux for about 4 years now), so maybe there's some stupid little box somewhere i didn't check or something. any ideas?
the laptop is an HP Pavilion dv9000, the distro is Ubuntu Studio 10.4, and the wireless card is a broadcom, and is installed/active according to the hardware drivers window. i've seen some posters having a problem in 10.10 with everything appearing to work, but just... doesn't. haven't seen a solution for that particular problem though

I have a Dell Vostro 1400 with a BCM4311 Broadcom wireless card that I just reinstalled with 11.04 from 10.04. I have the drives installed and it seams to be working when i run the 'Additional Drives', but I can't get the wireless adapter broadcasting. I followed the instructions given in the knowledge base on installing Broadcom Wireless, to see if I could get it running and that is where I saw the difference between the example and my computer when writing the 'sudo lshw -C network' command. In the example it said it was broadcasting under configuration (just like my wired networks below) and in mine it does not (see below for copy past).
I can't find a tickbox in the systemtray to enable the wirless networking that I had before the update to 11.04 (the 'Enable Networking' tickbox is still there and the wired network works fine - that is how I got online to do this post). I have the hardware switch turned on and I have been in the BIOS and made sure that the Wireless is enabled.Anyone who knows what could be wrong? Where could I go from here?Quote:

My problem is the computer does recognize the wireless connections but when I put the wep key It just start trying to connect and then asks for it again, and this goes on and on and on. I'm pretty sure I got the key right so I have no idea whats going on. This happened to me to with the previous version of ubuntu and also with fedora and installations in virtual pc, or virtual box. Even normal installations with partition. This time I'm using wubi. I didn't get anything with the grep part, I must have done something wrong.
1) PC Brand and Model:
Easynote MX65 P 057
2) Wireless brand, model and chipset:
Using grep in lspci -nn I got this:
03:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection [8086:4222] (rev 02)
Just in case I'll put the whole information:

Ubuntu 10.04 fresh install 64bit. Wireless was working in 9.10, now does not even show up in restricted drivers. Installed bcwl-kernel-source, and b43-fwcutter. ifconfig, iwconfig only show eth0 and lo - no wlan
Other restricted drivers show up - using NVIDIA driver with Compiz running better than ever on 2 screens
Here is the output from the collectNWData script found at [url]
I do notice that in the firmware section that both b43 and b43legacy are listed. Somewhere I reads that I should be using b43 - not the legacy version. Should it be blacklisted?

I'm working on Lucid, in HP Pavilion 9730us laptop.
My wireless broadcom card was working just fine until now as i installed it with the Hardware Devices manager, Today i put a new ALFA AWUS036H usb card to work with aircrack. both cards were working together for a while, but as i started playing around with aircrack the broadcom card of the HP has stopped working.
I made a mistake and followed the aircrack tutorial for R8187 / ieee80211 stacks driver, while i'm using RTL 8187 / mac80211 stack drivers, and blacklisted the RTL8187 , rebooted and then both card didn't work. I un-blacklisted it, and the ALFA is working but the broadcom not!
iwconfig shows me only one wireless card on wlan0 the blue light showing activity in the HP card doesn't go on.
Tried to uninstall and reinstall broadcom drivers, still no change.

I am new to Ubuntu and have just installed Ubuntu 10.04 on a Dell D600. My wired network is working perfectly however, my wireless card is unable to detect wireless networks. I am using a Broadcom Corporation BCM4306 wireless card. I have updated the drivers and it is installed correctly as far as I can tell. My card seems to be working, but it doesn't detect any wireless networks. I know that my wireless is functioning, because I can log on successfully with a windows laptop. In addition there are 5 or 6 other networks available, so it should be able to detect something. I am new, so please let me know what information you need and, if possible, how to find it.
Here is the results of "lshw -C network" from the terminal below:
