your build must have had something different, because i have downloaded the freshest rpi5 nightly build nightly-20230930-dd26ba0 (RPi5.aarch64) and i still have no driver attached

edit: nevermind :headslap: i see the newest files are not on top of the build listing like usually, but on bottom instead
the build LibreELEC (community): nightly-20240406-4b7642d (RPi5.aarch64) works right away and the driverrtw_8822bu is correctly assigned, thanks!

so, to answer this thread in the end, for anyone looking for a decent connectivity usb dongle, that is also supported by LibreELEC, it can be Archer T4U, but you have to use a nightly build lol (for now)
