5GHz wifi not working
#1
I have a new Pinebook Pro (August 2022 run).  It works fine in all other respects, but I have had zero luck with it recognizing 5GHz wireless networks with the included Manjaro distribution, a new Fedora installation, and a new Manjaro installation.  The 2.4GHz wireless service works fine, if a bit slowly.  The only way that I have managed to get 5GHz wireless to work is with an external RTL8812AU USB device (which worked immediately without any necessary configuration).

Is this a known issue?  If so, is it a hardware problem or a software one?  Am I missing a firmware update?

Same issue here. Same batch from early August. I can see 2.4GHz networks and connect to them but no 5GHz.

I have this issue as well, but haven't been able to narrow down the cause yet.

Interesting.  I opened a case with Pine64, and they suggested that it is not a hardware problem.  But, it appears that neither 802.11ac nor 5GHz are working for me, and I am limited to 2.4GHz 802.11n.  Again, this has been tested on my machine with the default Manjaro installation, a new Fedora installation, and a new Manjaro installation.

You might try an older firmware,,, it is ap6256-firmware
In settings, 3rd party, enable AUR
Install downgrade, a shell script,,,refresh
(as root, in term,,,, downgrade package and follow prompts)
Since it seems to work OK, and the update at the time didn't
I am still using (and pinned) the mid jan 2020 firmware

Fwiw, I tried it with the Manjaru that came with it, and DietPi.
I haven't done anything else with it yet. 5GHz does work on the 2020 PBP I have with Manjaru. But frankly I'll have to check if that's what it's still using since it's been updated.

I have just tried different older commits of the ap6256-firmware:

056d5f67 (the latest),
007c6dd1,
910f0df6,
eb15da6a,
90e56f5a,
83212fbe,
af1986f2,
a30bf312,
1f72cede

Compiled them into packages, installed them, rebooted, verified wifi with nmcli. Nothing. None of them have drivers that can see the 5GHz WiFi network. Maybe if you try some of the others we might get lucky, but I doubt it.

I think a fix might be from Kali: https://gitlab.com/kalilinux/build-scrip...issues/286

Try downloading the 3 files here to your /usr/lib/firmware/brcm folder: https://gitlab.com/kalilinux/build-scrip...rmware/pbp

I found that I didn't have 5ghz wifi with my fresh Armbian install but adding those firmware files from Kali fixed it.

I booted Armbian from MicroSD and it sees the 5GHz WiFi networks.
