PinePhone Pro and inaccessible WiFi channels - aigilea - 02-23-2022
I run my WiFi on channel 13 (2472MHz 20MHz width) and channel 142 (5700MHz, 40MHz width) because of high congestion. It's legal where I live and I never have any problem because of that.
PPP EE works fine with both bands out of the box with stock firmware, however most third party distributions like the latest mobian refuse to work with these channels, SSIDs are just not visible on the phone.
Changing channels to something more common works this around, but noticeably reduces performance for other devices because of congestion.
iw reg get lists these frequences as usable:
phy#0
country 99: DFS-UNSET
(2402 - 2482 @ 40), (6, 20), (N/A)
(2474 - 2494 @ 20), (6, 20), (N/A)
(5140 - 5360 @ 160), (6, 20), (N/A)
(5460 - 5860 @ 160), (6, 20), (N/A)
There is no regulation data in system so regulation setting is bogus, but installing CRDA and setting a proper regulation domain doesn't result in anything.
I've tried to remove stock "brcmfmac43455-sdio.bin", "brcmfmac43455-sdio.clm_blob" and "brcmfmac43455-sdio.pine64,pinephone-pro.txt" from /lib/firmware/brcm and use firmwares from different images for PPP and PBP instead, the best I could get to is using "brcmfmac43455-sdio.bin", "brcmfmac43455-sdio.clm_blob" and "brcmfmac43455-sdio.txt" from /lib/firmware/updates/brcm (note the updates subdirectory) of the stock system.
This way I can use my 5GHz network, but 2.4GHz is still not accessible.
Have anyone else run into this issue? Any ideas on how to fix?
