Issue description

USB WiFi adapter stopped working after update from v35 to v40

Detailed reproduction steps

I have a TP Link USB WiFi adapter (TL-WN725N) connected to my Powkiddy A13 running Batocera v35 (2022/09/11) and working fine. I updated to v40 from the main menu on the device. After the update to v40 ( 2024/08/09 ) wifi stopped working. Everything else works ok after the update.

Details of any attempts to fix this yourself

The work-around is to use a USB ethernet adapter which works with v40.

Details of any modifications you have made to Batocera.

I updated from v35 to v40

[deionut]

Here is the support file
batocera-support-19800101000230.tar.gz

[dmanlfc]

try this, create a file called r8188eu.conf and in the file type blacklist r8188eu.
save it to /etc/modprobe.d on the powkiddy.
then batocera-save-overlay
finally reboot.

Thanks for the reply; I followed your instructions but unfortunately it still doesn't work; I created another support file (attached). I noticed when there is no internet connection the name of the support file starts with 1980, when I connect the ethernet adapter the support file starts with 2024; The time displayed on the Powkiddy's screen is the correct time (hh:mm) even when the USB wifi is attached.

try to change it to blacklist rtl8188eu, save the overlay & reboot.

[deionut]

still doesn't work; another support file
batocera-support-19800101010439.tar.gz

[dmanlfc]

try this v41 build...

I copied boot.tar.xz and boot.tar.xz.md5 to \batocera\share\system\upgrade
I then rebooted; however after the reboot the version displayed is still the old one; the contents of the upgrade directory on board have not changed; Putty SSH output:

From Powkiddy: going to menu->System settings->Information the version displayed is 40o 2024/08/09, so the update didn't seem to have taken place. The wifi USB adapter is not working.

[dmanlfc]

Read the readme...

Bye, I dont have the same wifi adapter but it used to work till 39 version, since 40 it stopped to work and it doesnt work in 41 beta too.

Powkiddy won't boot now, even if I switch it on from the power button, I will flash again the SD card with the original version
batocera-rk3128-powkiddy_a13-35-20220911.img.gz and hopefully it will boot

[deionut]

I booted again to v35 and upgraded from the Batocera menu to v40 ( 2024/08/09 ). The same, WiFi worked with v35 but not with v40

Using wpa_supplicant forcing ssid and password i get ipaddress but network doesnt work.

Problem seems to be fixed on buildroot.
