Cannot get my broadcom 4312 to work 12.2

Hi all

I am using a Dell laptop with broadcom 4312 wifi built in modem. I tried everything but cannot get it to work. Network manager doesn’t even pick it up.

Please help me to get this to work.

Lets be sure exactly what you have. Please post result of

/sbin/lspci -nnk | grep -iA2 net
uname -a

Wow, thanks for the fast reply :wink:

It says

Kernel driver in use: b43-pci-bridge

If you have an active wired connection
Use your mouse to copy and paste this in a terminal

sudo /usr/sbin/install_bcm43xx_firmware
  • It may crash the desktop
    Don’t panic, just wait a few minutes, then force a reboot

Your wireless should work now

You kind sir is the worthy recipient of my Super Hero badge for today :slight_smile:

Thanks, is working now.

Thank you

Happy to hear it’s working

After following the steps of this thread to a t, my wireless is still not working. I am using the same model wlan card (the broadcom 4312) on a 64-bit install of SUSE 12.2. As your predictions told, the desktop crashed, however instead of a force-reboot (I panicked because I didn’t read the full post), I changed the session and resumed KDE. From there, I rebooted properly by means of the menu, leave, reboot buttons.
After a reboot, the wireless is not working. Any suggestions?

Go to the wireless forum and read the stickies. That will help you diagnose the
problem and tell you how to report information that we can use to help you. My
crystal ball is broken.

You should post the result of

/sbin/lspci -nnk | grep -iA2 net

My problem is rather different. I have a Samsung RV511 laptop with an i5 processor & 6gb RAM which is just over a year old (I took delivery on 27 Nov '11). There are 8 machines of varying antiquity in this house but this is the only one which has suddenly decided not to recognise our Netgear router. All the others are fine.

12.1, which has been installed since I got the machine - and has been trouble free until now - ceased to work a few days ago & the installation of 12.2 gives the same result. I also tried various “Live” disks & installed Mint to see whether a Debian system would fare any better - NO!

The output from this machine is as follows:

linux-bxg8:/home/dmk_suse.12.2 # iwlist wlan0 scan | grep -i ‘essid’

ESSID:“BTWiFi-with-FON”
ESSID:“BTWiFi”

The output from my Dell netbook is

                ESSID:"BTWiFi-with-FON"
                ESSID:"BTWiFi"

The ESSID: “Netgear” is the one I use and ESSID: “Powerbook” is something my son has on the same router to handle WEP. I don’t know where any of the others are but “BTWiFi-with-FON” is a BT hotspot. I have logged on to that, so I know that wireless is working.

One final note: BT have been installing fibre optic into the village here and this problem started as they finished - but that may just be coincidence!? At the moment, I’m using the Samsung running off a cable from the router and it works fine.

Hi
Channels and frequencies of the router and new AP’s?

Maybe your signals are being swamped by the new AP’s.

When you run your test, where are you in location to the wireless
router? Can you test right by the netgear router.

@Malcolm - Thanks for the quick reply. Sorry I haven’t got back sooner but I didn’t realise we’d moved to page 2. I usually work about 12ft from the router but I went & sat at my son’s desk, which is where the router is, and tried again. No luck for me I’m afraid - but I did pick up the ‘Vellasrv1’ signal which is coming from the offices of Vella Associates on the other side of the road. My son’s room is at the front of the house & his desk is by the window facing the road which may account for the fact that when I moved back here, to my normal position, Vella disappeared - as did several of the BT signals.

Output from son’s room:

ESSID:“BTWiFi-with-FON”

Channels and frequencies of the router and new AP’s?

The channel is set to Auto and the bandwidth is 20/40MHz. There are 13 channels available. I don’t know about the other AP’s (I’m guessing that AP is an acronym for Access Point & refers to all the BT stuff cluttering the ether) but if you need information about them you’ll have to spell out what I need to do. I have to admit that I’m almost completely ignorant on the comm side of computing. My Ist iteration of SuSE was 6.3 (1999) and it’s taken complete care of that side ever since. This is the 1st time it hasn’t worked out of the box.

My son takes care of the router. I just leave him to it. I’m the only person in the house using Linux. Everyone else uses some flavour of Mac or Windows. One further thing, I re-installed Windows 7 to see whether the fault was general or confined to Linux. Confined to Linux I’m afraid. Widows is fine.

Hoping that you can come up with something. If you need anything else, let me know and thanks for your help so far.

Hi
Use the iwlist command to see what channels are working on which frequency…


iwlist wlan0 scan | grep -i 'Frequency'

Sure you have the right authentication code when connecting to the AP your wanting to?

So to be clear. The same machine, if using windows, can connect to the AP?
When using Linux it cannot? But it can connect to other AP’s?

And you said:

12.1, which has been installed since I got the machine - and has been trouble free until now - ceased to work a few days ago & the installation of 12.2 gives the same result.
Which suggest something changed at the AP to me.

You also said

I also tried various “Live” disks & installed Mint to see whether a Debian system would fare any better - NO!
Excellent idea, but you would need to have added the firmware to thee Live session - correct?

I must obviously learn a bit more about iwlist! This data was taken from the Dell, hope this it’s ok:

Interestingly this is the first time TALKTALK have turned up - they are our supplier of 'phone & broadband. I’ll try to find out more.

@malcolm - yes, the authentication code (I am assuming this is the WPA key) is the same one we have always used - this is the first thing I look at when any trouble arises. It’s about the only thing I know!

@caf4926 - 1) “So to be clear. The same machine, if using windows, can connect to the AP? When using Linux it cannot? But it can connect to other AP’s?”: This is correct! Samsung gave me a Windows 7 disk with the machine & I reinstalled - ****, I dislike it, but it did connect to the Netgear without problem. Using the 12.2 installation, I also connected to one of the BT hotspots without trouble & poked around amongst their offers Etc. Unless your a BT customer they charge £5 a day to use the service so I didn’t go any further, but I did move between various BT sites. It was a perfectly kosher interenet connection.

  1. “Which suggest something changed at the AP to me” - and this. along with computer malfunction, was also my 1st thought. But, if this was the case, why are none of the other computers affected? And the Dell netbook (running Linux & on which I’m writing this) has never even hiccuped! My son assures me that there have been no changes.

  2. “—you would need to have added the firmware to thee Live session - correct?” - Um! I’m not sure what this means. In the past, when I have run live disks all I have done is click on the network manager, pick Netgear from the listed AP’s, selected WPA, put in the key & it’s worked. I have used this method to check for minor faults from time to time without difficulty. Is there something else I should do?

Thanks for your interest.

Hi
Both on the same channel and power…hmmmmm

So on the netbook, what are the results for wireless command you ran
(with the freq etc), the same?

So if the Powerbook is disabled temporarily, does the Dell connect?

@Malcolm - The power book is one of my son’s (Doughal’s) collection of aging Macs. It only has WEP - not WPA - and he’s set up it’s own AP. It’s been there for some time - long before this started.

We are going to set up static IP address, fiddle about and see if that does anything.

My own feeling is that this is a Linux/Samsung/Netgear/(possibly)fibre/{and, maybe)TALKTALK problem - but I’m well out of my depth. There have been problems lately which we have put down to to the work BT has been doing - and it is interesting that the BT sites are predominantly visible.

I shall continue to follow this thread in the hope that something comes up and will get back if I sort anything out - I personally favour standing on my left leg with a light bulb in my right ear - BUT, like Cpt. Oates, I may be gone for some time!

There is no reference to a wireless driver for your device in the 12.2 stock kernel. Packman has wl-broadcom which I believe supports your card, but has a proprietary license and therefore is not included in openSUSE. May I suggest that you run over to the wireless forum, read the stickies very closely, and follow the instructions to the letter. There are people there who can help you sort this out.

Please, no fiddling.
