    Ubuntu laptop cant use wifi


    I just got this laptop for free as a hand me down and wanted to reformat it. Didn't get a disk and there was no recovery partition so I decided to try out a free OS. I am liking it for the most part but have had a really hard time getting wifi to work.

    Here is what I have figured out so far.
    02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5705M Gigabit Ethernet (rev 01)
    02:03.0 Network controller: Broadcom Corporation BCM4309 802.11a/b/g (rev 02)
    Using Ubuntu 10.10

    Assistance would be greatly appreciated!

    Welcome to the forum.
    Wifi is one of the most complained about items. There are lots of threads for you to review, but we will need info on your computer, wifi card, and linux version you are running.

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    Open System->Administration->Additional Drivers - you should find the drivers for your Broadcom B43 wireless hardware there. That's what you need to install. FWIW, 9.04 would install those drivers automatically, but since they are proprietary, you need to do that manually for 10.10.
    Sometimes, real fast is almost as good as real time.

    I went to the link, downloaded the simple application and ran it. Got a list of info in a text file. Cannot copy the info into this post because it seems my account is not allowed to post urls yet (which is a good way to stop spam bots). Hopefully I wont get banned for circumventing it.

    I tired to activate the driver shown there but it said system error. I also noted that it said "Supported chipsets:- BCM4301- BCM4303- BCM4306/2" and mine I believe is bcm4309.

    Ok. Your wired ethernet seems to be healthy. The message from dmesg about the firmware is probably the key thing. Some of these "legacy b43" boards need proprietary firmware downloaded to the device in order to work properly. The messge said:
    ============ dmesg-firmware ============
    [ 19.044220] b43legacy-phy0 ERROR: You must go to linuxwireless.org/en/users/Drivers/b43#devicefirmware and download the correct firmware (version 3).
    which is the relevant/necessary information.

    That page had a lot of info... I seemed to pick the wrong thing to try to install and it failed. Could you narrow it down a bit?

    Sorry about losing track of this thread.
    From what I can tell, this device is not supported by b43 or legacy, you need the wl driver. Your device is 14e4:4324 which the link above says is not supported and the WL driver as an alternative but on the WL page, it says it isn't supported either.

    Maybe I'm just reading it wrong.

    So my laptop cannot get wireless at all with Ubuntu? Is there another linux OS I could/should be using instead?
