I very often use my L5 as hotspot AP for my laptop, the L5 is using data mobile to connect to Internet. Enabling is simple from Settings -> Wi-Fi. I often encounter the problem, that after a short moment Settings falls back, saying no WLAN adapter would be there. I have to reenable Hotspot again, sometimes two times, and then it works fine without any hick-up for hours,
Any ideas?
This happens to me also, quite often. Just like you describe it, for me also it works a very short time, a few seconds maybe, then breaks. Then it can work for hours on next attempt. Probably a bug, maybe in the kernel.
I totally confirm this behavior. I use the hotspot quite often, and it see this often as well.
I created an issue for this.
I use the Redpine WiFi module. What do you use?
I use redpine_91x, firmware version 1.2.20.0
Same here.
Well done!
I captured /var/log/messages (FreeBSD) and /var/log/syslog (PureOS) of the relevant time window and attached them to the issue. The interesting parts are:
FreeBSD:
$ grep 'Trying to associate with 88:da:1a:7c:30:1c' messages.1

PureOS:
$ grep 'Started Wi-Fi' syslog

I.e. PureOS’ NetworkManager started three times the hotspot and only with the 3rd time FreeBSD could associate succsessful.
Did you do: change the operation mode to dev_oper_mode=14?
I still have dev_oper_mode=5:
$ cat /etc/modprobe.d/librem5-devkit.conf | grep dev_oper_mode
options rsi_sdio dev_oper_mode=5
options redpine_91x dev_oper_mode=5 rsi_zone_enabled=1 antenna_diversity=1 wlan_rf_power_mode=0x00
I have the same values like you.
Here is a link to the meaning of the dev_oper_mode.
Snippet from that file:
5 - Wi-Fi station + BT classic mode
...
14 - Wi-Fi AP + BT dual mode
But, I do want to use my L5 mostly in station mode and sometimes (once a night) in AP mode.
Is there somewhere an exact technical explanation about what the different config values in the driver(?) mean?
Maybe it’s not a bug in the kernel, but in the GUI of settings. I have here a case from yesterday evening: I started hotspot exact at 20:51:00 and from my feeling at 20:51:02 the GUI jumped back to a page “No WLAN adapter”. There is nothing as error visible between 20:51:00 and 20:51:06, at 20:51:06 I toggled the WLAN kill switch to bring back the interface WLAN:

I moved on May 30 to a new L5 with a SparkWLAN Wifi card. Since then the hotspot does not fall back again to normal Wifi. See here for other observations related to this change: FOSDEM 2024 talk by Sebastian Krzyszkowiak about USB suspend/resume bug affecting Librem 5 - #29 by guru
