Thread: 2017 MBP Unable to connect to 5 Ghz networks

    Alright. Then I'm curious how broadcom-wl would perform and it's probably a good learning opportunity.

    How do I remove the brcmfmac drivers? Searching brcmfmac in YaST Software Management shows no results

    Running `sudo rmmod brcmfmac` also did not seem to work

    May have found it in YaST: 'kernal-firmware-brcm` so would I uninstall that and install `broadcom-wl` or are there more steps?

    Hi
    Well, just install the broadcom-wl and broadcom-kmp packages, run `mkinitrd` and reboot to see what happens.....

    Could also check drivers in use via;
    Code:
    /sbin/lspci -nnk | grep -A3 "Network"

    Current driver:

    Code:
    03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 02)
           Subsystem: Apple Inc. Device [106b:015a]
           Kernel driver in use: brcmfmac
           Kernel modules: brcmfmac, wl
    After installing broadcom-wl, broadcom-kmp, and running mkinitrd then rebooting:

    Code:
    03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 02)
    
            Subsystem: Apple Inc. Device [106b:015a]
    
            Kernel driver in use: brcmfmac
    
            Kernel modules: brcmfmac, wl
    Is there a step I'm missing? Not sure anything changed.

    Hi
    Well it can use wl as shown is available, so what you could do is add `blacklist brcmfmac` to the blacklist file (location in previous post) and then run mkinitrd, reboot and check the lspci output and test if working. Else revmove the broadcom-wl packages, rebuild initrd and reboot use the oss driver...

    HTML Code:

    No change in lspci but in the networks UI, I have no option to use any wifi features. I'm going to revert this.

    Default AW: 2017 MBP Unable to connect to 5 Ghz networks

    I think now, broadcom-wl does not support this Chip?

    Not really sure. All I know is blacklisting brcmfmacs and installing broadcom-wl in its place did not work
