A06; wifi not detected

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

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

On raspberry pi 400 which can access this wifi I check the details:

7.b:~> iwconfig

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)

Welcome to the Wi-Fi world, a world where things looks super simple on the user side, and is utterly complicated under the hood.

The DevTerm do not use the same WiFi chip as the Raspberry Pi, and wifi under linux has always been a fairly complicated thing to get it to work right. Even big companies have issues with they product with one or other access points, Phone Wifi sharing has also always been a problematic one, it is sadly fairly common to have devices that do not connect to them, or even do not see them…

It can be sadly anything. You could try to compare the output of iw list between your raspberry pi and your devterm to see if there is any difference in what both do support.
Channel, bitrate are generally not the problem for a device not seeing or connecting to another.

Have you tried to use iwconfig to scan for your phone? Phone tethering tend to now show themselves as normal AP so the devterm driver may filter them out?

Someone from CPi may be able to help better.

Hi, I have had this issue with phone hotspot, so far I can’t give an explanation and it has happened to me with many types of devices, not only the DevTerm or SBCs. On my phone I have this setting called device identificator with two options

I never had this with older phones, but when I can’t see my wifi I just change whatever is selected to the other option and starts working. But still, I have no real explanation why that happens or works.

Thanks for the replies.
Unfortunately my phone gives me absolutely no control about anything else than the screenshot.

I checked how raspberry pi 400 sees my wifi by sudo iwlist scan:

but I didn’t look at it closely yet.
In the meantime I managed to share the internet connection over bluetooth so that’s a workaround for now.

diff -y output:

left is the pi, right is the devterm.

Can you try switching your phone’s hotspot from Channel 13 to Channel 12 or below? I’ve noticed before that some Wi-Fi devices supposedly available for international use aren’t properly tested on non-US-licensed Wi-Fi channels, meaning 13 and 14 simply don’t work properly.

If only I knew how to do it, I would.
The only options I have in the phone’s (hammer iron 2) gui are:

  • name,
  • password,
  • protection (wpa2 psk or nothing)
  • band (“2,4 GHz” is the only option I have)

and that’s all.

I’m having issues with wifi attaching and loosing - looked up online - my NetGear router is several years old and may not be up to everything that attaches to it (tablets, Raspberry pi’s etc ) I’m using a USB/ethernet adapter now for software updates - much more stable but I ordered a newer router… will upate the group if that fixes things.
