Package: firmware-realtek
Version: 20250410-2
Severity: important

Dear Maintainer,

My system has been upgraded to trixie (arch armhf/raspberrypi).
Before upgrading to trixie, the wlan had no issue using an usb-key based on chip RTL8188EU.
It worked as expected on "bullseye" and "bookworm".
   
After upgrading to trixie, the wlan connects properly on startup, but it stops working after
1 or 2 hours or even after few minutes.
The device status becomes DOWN, and the only way to make it working again is to reboot the
system or unplug/plug manually the usb-key.
   
Finally to fix the issue I had to copy the old firmware file "rtl8188eufw.bin" from the
"bookworm" package, and then override the file installed by the "trixie" package.

It seems the "trixie" package provides a new revision for this firmware, but it doesn't
work properly and make the device unstable.

I suggest to revert the firmware upgrade (rtl8188eufw.bin) to the previous revision provided
in "bookworm" (which is the same revision as "bullseye" and old debians from 2013).

Best regards
