Hello.
I need a WiFi USB adapter for a desktop PC running EOS.
I found several products on Amazon and the description of some of them mentions Linux as a compatible operating system (I simply searched for “usb wifi linux”). Do you have any experience on this? Could you please recommend some models or advise me against others?

Tp-link AC600 Archer T2UB Nano + Bluz 4.2
(USB wifi + Bluz, not expensive, rare to find Usb wifi with Bluz)

$ yay -S rtl8821cu-dkms-git (need to compile)

edit or create /etc/modprobe.d/8821cu.conf ::

options 8821cu rtw_led_ctrl=1 rtw_power_mgnt=0 rtw_enusbss=0 rtw_ips_mode=1 rtw_vht_enable=2 rtw_ht_enable=1

$ sudo wifi-menu
$ sudo iw wlan0 set txpower fixed 3000
$ sudo systemctl restart systemd-modules-load.service
$ sudo systemctl restart NetworkManager
After reboot os

if not working,

$ sudo ip link set enp1s0 down

$ sudo ip link set enp1s0 up

or if not working,

$ sudo ip link set wlan0 down

$ sudo ip link set wlan0 up

I run a AX1800 USB adapter, it also requires additional package rtl8812au-dkms-git which provides a module named 8852au. It does 1200 Mbit + 600 Mbit. Costed like 25 EUR.
