• Live USB and no wifi

    Hi everyone,

    I am getting ready to install Antergos for the very first time but have a wee problem with wifi - theres no option for wifi at all in the network manager.

    The laptop I want to install Antergos on is currently running Manjaro and there was no problem with wifi at all.

    Hardware configuration under Manjaro is showing BCM43225 (network-broadcom-wl)

    Is there anything I can do to make it work with Live USB so I can proceed with the installation?


  • @m4g1c

    Could you connect to the wired or ethernet network? Then, when connected, download the package:

    yaourt -S broadcom-wl-dkms

    That is all

  • From ArchWiki:
    The kernel contains two built-in open-source drivers: brcmfmac for native FullMAC and brcmsmac for mac80211-based SoftMAC. They should be automatically loaded when booting.
    brcmfmac supports newer chipsets, and supports AP mode, P2P mode, or hardware encryption.
    brcmsmac only supports old chipsets like BCM4313, BCM43224, BCM43225.

    It is supported by the kernel.

    ip link

    will give you the detected devices.

    sudo ip link set interface up

    will bring it up, interface needs to be the devicename of your card you get with the former command…

  • You can also do

    ip link

    Write what you throw here

    I apologize, we post almost at the same time, if my answer does not seem right, erase it without problems :)

  • @judd i write the same before so we have the same opinion ;)

  • @joekamprad said in Live USB and no wifi:

    Have the same opinion, it’s very good :);)

  • Thank you guys for quick replay!

    ip link gives me this:

    [[email protected] ~]$ ip link
    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
        link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    2: enp1s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
        link/ether 1c:75:08:4a:80:dd brd ff:ff:ff:ff:ff:ff
    [[email protected] ~]$ 

    I am pretty new to linux so not exactly sure what to put as interace. I’ve tried enp1s0 but that didn’t work.

  • @judd

    [[email protected] ~]$ iwconfig
    enp1s0    no wireless extensions.
    lo        no wireless extensions.
    [[email protected] ~]$
  • so seems like wifi is not detected.
    try to enable the driver manual:

    sudo modprobe brcmsmac

    and see if your wifi is enabled then again with:

    ip link
  • @joekamprad that worked perfectly. Thank you for taking your time to help with my problem, you’re a rockstar!

  • @m4g1c 😊
    Nice to see that it has worked, BROADCOM has a very insufficient Linux driver support. You were lucky it was an older chipset
    Hope your installation went fine, and wifi still working after reboot then…

  • @joekamprad
    Took longer then it should but its totally my fault or should I say weather and problems with network…

    Long story short - it’s done :) and thanks to you wifi works without a problem!
