• Firmware/wifi issues

    Hi All,

    I have a Dell XPS 9550 with antergos and windows dual booted. A couple weeks ago there was some sort of fault, my laptop crashed, and antergos was gone from the windows boot menu. Using a live usb I reinstalled grub and added a new boot option for antergos in the windows boot manager. This seemed to work fine, however once booted into antergos the wifi adapter seemed to be disabled. From my digging it seems to be a firmware issue, but I cant reinstall linux-firmware. Does anyone know what’s going on?

    Do you have the directory


    There should be three files. If you don’t have it, maybe you have dome older version of it?

  • Sorry about my typos, I just bought a new crappy keyboard, unfortunately…

  • The problem sounds like a disk fault after the crash.
    So I recommend making a backup first of anything important. And maybe a reinstall…

  • That directory does exist and contains one file called “mtree”.

  • Fixed this issue by deleting the folder you specified and updating linux-firmware. I then rebooted and started the bcrmfmac module. My wifi card now appears in ip link and is functioning normally. Thanks!
