unreliable wifi

[pppqq]

hello,
I have installed tinycore on a raspberry pi zero and am investigating if it is going to be useful.
I installed firmware-rpi-wifi and wifi.
I bring up the wifi link using wifi.sh, entered the ssid and password ok.
The link is established initially (using wifi.sh -a) but after a while it drops and takes a long time to re-establish.
I can initially log on with ssh (i want to run the pi headless) but the link fails after a short while and rarely resumes.

I can run the same sdcard on a pi B  using an ethernet connection and that is very reliable.

There is nothing wrong with my wifi as i can run the same pi reliably using raspian and ultibo builds.

I do not own a pi Zero myself, but are you not able access it using serial / usb cable to the pi to check logs, dmesg ?

maybe you can run a script  in a loop to dump dmesg output every minute to a file in /mnt/mmcblkXXX/tce folder , so you can read them after a reboot

[Paul_123]

What version did you install, if you are using 15.0 did you read the known issues on the release announcement?

[pppqq]

i am using version 15.0 - didn't see anything about wifi in the installation notes.

I want to know if the packages i have installed are the "right" ones or if there's something better.

The raspian wifi handling seems to be rock solid - are the TC packages derived from that code ? or re-invented.

[pppqq]

the post you mention seems to sum up the same problem i am getting.
However, it is nothing to do with signal strength etc. since I can get a reliable connection with Raspian with the the same hardware, location and wifi network.

Its in the release posting here.  https://forum.tinycorelinux.net/index.php/topic,27338.0.html

It is because piCore has upgraded to wpa_supplicant 2.11 which includes better WPA3 support.  However the driver for rasberry pi wifi chips is not fully compatible.  It is just now getting fixed in the mainline kernel.

[Rich]

Hi Paul_123
This post seems to confirm it's a wpa_supplicant 2.11 issue and points to a
reversion that supposedly fixes it:
https://github.com/raspberrypi/linux/issues/6049#issuecomment-2500234998
I think I also read somewhere that it occurs when running wpa2 and wpa3 at
the same time.

[pppqq]

so should i go to version 14.0 to get over this ?

[Rich]

Hi pppqq
I noticed this at the end of your dmesg:

Code: [Select]

[   46.719961] brcmfmac: brcmf_cfg80211_set_power_mgmt: power save enabledDoes the situation improve if you disable power save?

Something like:

Code: [Select]

sudo iw dev wlan0 set power_save offor maybe:

Code: [Select]

sudo iwconfig wlan0 power off
Replace  wlan0 with whatever your device is called.

[Paul_123]

so should i go to version 14.0 to get over this ?

If you read the post I linked, it tells you how to solve it.

[pppqq]

turning power save off does not work.
adding brcmfmac.feature_disable=0x82000 to cmdline does not work.

As i am evaluating this os i do not wish to get bogged down in adding temporary patches. This will take more time than installing a fresh version.
So my question of going back to 14.0 still remains unanswered. What version do i have to go to to have reliable comms ?

[Paul_123]

All of my wifi devices (including pizero) work just fine, so I’m not sure what is causing your problems.

Have you connected a display and keyboard to see what is happening/errors when the wifi stops?
