• Broadcom Limited BCM43142 (no Wifi) issues.


    Hi.

    Only way of connecting to the internet is through the Ethernet cable.

    ifconfig: wlan0 is not listed
    lspci: Network controller: Broadcom Limited BCM43142 802.11b/g/n (rev 01)

    Found a .deb package with the required driver pacman U returns an error (damaged package[link from Ubuntu Forums])

    also tried: rfkill

    Thanks in advance!!

    Unload conflicting modules.

    su
    rmmod b43
    rmmod ssb

    Should work… builds modul for both nstalled kernels (as dkms should) a reboot will load the modul also…

  • This seems to be the problem:

    ==> No kernel 4.9.47-1-lts headers. You must install them to use DKMS!
    ==> No kernel 4.12.10-1-ARCH headers. You must install them to use DKMS!

    I am running the LTS version of Arch.

    When I start in normal bootmode I get a black screen. What might be an issue here.

    Thnx!

    normal bootmode

    means what?

    and headers are needed for sure.

  • i can see that kernel headers are optional dependency, because of different kernels…

    so you need to install the headers for your used kernel:

    sudo pacman -S linux-lts-headers
