Hello once again.
I have the following issue:
devterm (a06) does not see the wifi shared from my telephone.
This is very disappointing because for me it is the most important wifi to use on the devterm when outside.
My laptop (with debian 10, i386) and raspberry pi 400 can see this wifi.
devterm can see other wifi networks ok but not this one.
On telephone the configuration options are very limited:
Thought 1: what if the strange SSID name is problematic?
apparently not. temporarily changed to something simpler: “bleb”.
not working either.
Thought 2: maybe the region is set incorrectly and the wifi is on a channnel which is disabled by devterm?
I edit /etc/default/crda to set the correct region REGDOMAIN=PL and indeed:
6.b:~> iw reg get
global
country PL: DFS-ETSI
(2400 - 2483 @ 40), (N/A, 20), (N/A)
(5150 - 5250 @ 80), (N/A, 23), (N/A), NO-OUTDOOR, AUTO-BW
(5250 - 5350 @ 80), (N/A, 20), (0 ms), NO-OUTDOOR, DFS, AUTO-BW
(5470 - 5725 @ 160), (N/A, 26), (0 ms), DFS

(57000 - 66000 @ 2160), (N/A, 40), (N/A)

On raspberry pi 400 which can access this wifi I check the details:
7.b:~> iwconfig
eth0 no wireless extensions.

ok, so this wifi is on 2472MHz (channel 13), bitrate 24Mbps.
Back on devterm I check:

6.b:~>
from all this output the important part is that 2472MHz 24Mbps used by this wifi are available on the devterm.
so I don’t see any reason why this wifi wouldn’t be detected.
and somehow it is not.
I don’t know, how do I fix this?
(I can also share the internet connection from the phone through usb but then the phone will want to charge from the devterm which I don’t want)
