    Re: Please help BCM94311MCG WLAN wont detect hardware!

    I have to go for a sleep now unfortunatly. But please post and try and help me, il post back tomorrow. Thank you so much for your support so far.
    I just read that ubuntu buisness licenses are free, so if I get this wireless up and running and learn how to do it all, and maybe even get AutoCAD for Ubuntu, that would rock, but I dunno if windows emulator would handle that, but im sure theres a way.
    And if its feasible il run my 2 servers on Linux, and all the machines. And il donate the budget to your excellent cause.
    It would be around £10,000 which I think is around $20,000
    But im thinking way ahead. First I need to get my home network running first, then learn a bit more. But If this works out wireless on this machine, then that paves the way for the future of my system administration future.
    Thanks again.

    Talk to you tomorrow.

    ubuntu@ubuntu-laptop:~$ cat /etc/modprobe.d/blacklist*|grep -i -e bcm43xx -e b43 -e ssb -e wl -e ndiswrapper
    # replaced by b43 and ssb.
    blacklist bcm43xx
    This file should have b43 blacklisted also:
    Code:
    echo blacklist b43|sudo tee -a /etc/modprobe.d/blacklist
    It might be best if you reboot from here to see what happens.

    Can you post your lshw -C network? This one will tell us what is being used for your network cards and what drivers it is trying to use.

    Also, it does not seem that the following command worked:
    Code:
    echo -e '#Hardy ssb/ndiswrapper workaround, added' `date` '\ninstall ndiswrapper modprobe -r b43 b44 b43legacy ssb; modprobe --ignore-install ndiswrapper $CMDLINE_OPTS; modprobe ssb; modprobe b44;' | sudo tee -a /etc/modprobe.d/ndiswrapper
    When you posted your /etc/modprobe.d/ndiswrapper information, there was supposed to be an additional line at the end of the file that contained this information. Let's hold off on that for now. We might not need it.

    By the way, I might not be able to respond tomorrow until late because I am on the road tomorrow and will not be able to get online until night over here. I am guessing that I am six hours behind you.

    Question Re: Please help BCM94311MCG WLAN wont detect hardware!

    Ran the first command and got this:
    ubuntu@ubuntu-laptop:~$ echo blacklist b43|sudo tee -a /etc/modprobe.d/blacklist
    [sudo] password for ubuntu:
    blacklist b43
    ubuntu@ubuntu-laptop:~$
    Then re-booted and nothing had changed. Went into Ndiswrapper (System-Administration-Windows Wireless Drivers) and it said:
    Hardware Present: No

    So to run the Lshw -C network I got:
    ubuntu@ubuntu-laptop:~$ lshw -C network
    WARNING: you should run this program as super-user.
    ubuntu@ubuntu-laptop:~$
    So I ran 'Sudo lshw -C network'
    And I got:
    ubuntu@ubuntu-laptop:~$ sudo lshw -C network
    [sudo] password for ubuntu:
    ubuntu@ubuntu-laptop:~$
    So basically I got nothing, but it did flash up somethings before it went back to the 'ubuntu@ubuntu-laptop:~$'
    It flashed up real quick, the only one I managed to read said: 'PCI (sysfs)'

    Sorry that no doubt didnt help you much. Thanks again for your time man, just reply whenever you can. Iv always got my ethernet mean time, untill I get this wireless working. It just confuses me, cause its worked twice now, perfectly, and both times, after I re-boot it just wont detect the hardware again!
    Thanks so much for helping me out man.
    An yeah I think you are 6 hours behind me, so im usually sitting on this laptop at like 4am in our time lol.
    Thanks man, talk to you soon hopefully.

    I should have looked at your screenshots earlier, but I didn't. I was on dialup at the time so it takes forever to see anything. Anyway, I looked at the screenshot and realized that the bcmwl5 driver is no longer happy. When it says hardware present: no, then that means that the driver is not going to work with ndiswrapper.

    Can you post the results of:
    Code:
    ls -l /etc/ndiswrapper
    ls -l /etc/ndiswrapper/bcmwl5
    The first command is done to see what drivers have been loaded. The second command is where ndiswrapper keeps some information about the driver. I just want to see what happened. We then should use the commands:
    Code:
    sudo modprobe -r b43 b44 b43legacy ssb bcm43xx wl ndiswrapper
    sudo depmod -ae
    sudo modprobe ndiswrapper
    dmesg|grep ndiswrapper
    This will help us see what ndiswrapper does not like about the driver.

    One other thing, can you make sure that the card is turned on (if this is a laptop). Can you also post the results of lspci -nn|grep 14e4? I just want to make sure that the card is being recognized. Usually lshw -C network will show your card whether your card is on or not.

    Too bad you didn't post this last year when I was living in Peterborough. There would be no time difference.

    Re: Please help BCM94311MCG WLAN wont detect hardware!

    I am having the exact same problem except my BCM94311MCG is rev 01, whatever that means. None of the fixes have worked for me either, "lshw -C network" can't find the card while it is broken and neither can lspci or any hardware detecting software I have used.

    The card is switched to the "on" position on the front of my laptop but when I restart the computer the light will change from blue to red, as if I had switched it off, and it will stay red for days at a time until it randomly starts working again.

    After a few days of being undetected as hardware, it is finally working for this session, so I have taken the outputs of the following

    Code:
    lsmod|grep -i -e bcm43xx -e b43 -e ssb -e wl -e ndiswrapper
    lshw -C network
    cat /etc/modprobe.d/blacklist*|grep -i -e bcm43xx -e b43 -e ssb -e wl -e ndiswrapper
    cat /etc/modules|grep -i -e bcm43xx -e b43 -e ssb -e wl -e ndiswrapper
    
    cat /etc/modprobe.d/ndiswrapper
    
    ls -l /etc/ndiswrapper
    ls -l /etc/ndiswrapper/bcmwl5
    and saved them for comparing against the outputs after the card breaks again on reboot.

    Is there anything else I should look at now while it is working?

    I need my wifi to do work today, so I can't restart it anytime soon, but this is definitely a problem that needs to be looked at further.

    ubuntu@ubuntu-laptop:~$
    Other commands,
    First one did nothing (asked me for password, then went back to the normal command line)
    So I dunno whats up with that.
    Second one did the same again:
    ubuntu@ubuntu-laptop:~$ sudo depmod -ae
    [sudo] password for ubuntu:
    ubuntu@ubuntu-laptop:~$
    The third command (sudo modprobe ndiswrapper) did the same again as the quote above.

    But the last command gave me:
    ubuntu@ubuntu-laptop:~$ dmesg|grep ndiswrapper

    Doesnt mean anything to me, but I hope it helps you man. Iv tried removing the driver, then adding it again, and it just doesnt work. Except it has twice, and worked perfectly at that!
    Iv read on a forum about something called 'MadWIFI' or something, would that perhaps help?
    Thanks alot for your time again man.

    Durundal,
    Nice to hear someone is in the same situation as myself! lol!
    Its infuriating, because its worked before, so why cant it work again!!!
    You seem to know alot more Linux skills than myself though, but im guessing your still pissed too.
    At least we're not alone!

    Oh also, sorry to post again, three times in a row, but heres another screenshot I took from whn I click on 'Edit wireless networks' In the network manager at the top right corner. (Even though Ndiswrapper says: 'Hardware Present: No'

    Anyways the screengrabs attached.

    The last part that we need is the lspci -nnm information. It will give is the subvendor information that will help us match up the information in /etc/ndiswrapper/bcmwl5.

    As for MadWIFI, it is a driver that is for another card type (not Broadcom).

    Everything looks right, but the thing that concerns me is that the hardware is not present and nothing is showing up in lshw -C network. Do you have a HP? This is the issue that I had with my laptop and I found that there was an issue with the motherboard.

    By any chance, are you dual booting with Windows? If so, does the wireless work there?
