USB-WLAN-Adapter with antenna working out-of-the-box in Debian 11

#1 Post by buhtz »

Does anyone have experience with USB-WLAN-Adapters (including an antenna) on Debian 11 that run out-of-the-box without building or installing extra drivers/firmware?
Firmware/drivers installed via apt from the official debian repos would be OK for me.

Background:
I have problems to get a USB-WLAN-Adapter up and running using a RTL8811CU Chipset. I do not want to invest more time in build errors and just want to buy one that works out-of-the-box.

I have used the MT7601U Wireless Adapter with Buster, Bullseye, & currently on Bookworm.

Never installed a single extra thing for it. She is not a speed demon & only 2.4GHz but works well for me.

I'm happy with the Fritz!WLAN USB Stick AC 860, uses Mediatek mt7662 driver.
Real Debian users don't do chat...

apt install build-essential git dkms
