TP-link TL-WN821N(EU) Ver 6.0 : which driver should I use?

Which driver should I use for the TP-link TL-WN821N(EU) Ver 6.0 ?
If I plug it, dmesg reports:

Should I use the rtl8192eu from AUR?

$ grep -E '2357.*0107' /usr/lib/modules/$(uname -r)/modules.alias
alias usb:v2357p0107d*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu

Isn't that module auto-loaded according to lsmod?

Yes it is, but the wifi card cannot establish a connection.

Ah, I see. Tbh. I was more asking out of curiousity, I do not have any particular knowledge about that device.
But meanwhile some googling revealed this thread (German only). And according to it, rtl8192eu from the AUR might indeed do the trick.
Don't forget to blacklist rtl8xxxu.

Indeed following this thread https://forum.ubuntu-it.org/viewtopic.php?f=9&t=648781 and using the rtl8192eu AUR package and issuing the following two commands:

 echo "blacklist rtl8xxxu" | sudo tee /etc/modprobe.d/rtl8xxxu.conf

echo "options 8192eu rtw_power_mgnt=0 rtw_enusbss=0" | sudo tee /etc/modprobe.d/8192eu.conf

It seems to work.
