5GHZ wifi is not showing on fresh install

  • 772

I'm new to Linux. Apple stopped supporting my laptop (early 2011 Macbook pro 15) so I'm looking to join the linux family.

My laptop has a Broadcom BCM4331 2 band wireless card. It's this one...

03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4331 802.11a/b/g/n [14e4:4331] (rev 02)

I can access 2G and 5G bands fine on my OSX installation but on Linux I can only see the 2G option. I followed this guide...

Installing Broadcom Wireless Drivers

I followed answer 404, the lengthy one. On a previous installation I had 5G and 2g networks showing on Linux without a problem. But I had to re-install linux due to some issues and now I can only see the 2G option.

Does anyone know how to fix this? Would appreciate your help and guidance.

  1. I had the same issue, so in my research I replaced Ubuntu with Debian and found https://wiki.debian.org/InstallingDebianOn/Apple/MacBookPro/9-2 While it is not your and my MacBookPro version, it does the trick

    sudo apt install -y linux-headers-$(uname -r) && sudo apt install -y broadcom-sta-common broadcom-sta-source broadcom-sta-dkms

    then reboot

    reboot
