Realtek RTL8821AE issue

Hi.
I’m having problems with the RTL8821AE wireless card drivers when installing on a lenovo laptop. The same card works well on desktop raspberrypiOS, but it doesn’t work on dietpi.
Any instructions for that?
thanks in advance

Hi,

did you tried to install realtek firmware package. https://packages.debian.org/de/buster/firmware-realtek

Probably it’s installed on Raspberry OS be default.

yes, the firmware-realtek are installed.

What do you mean by “it doesn’t work”, which issue do you face, in case could you paste error messages you see?
