我在 ODROID H2+ 上运行 Ubuntu Server 20.04。我购买了基于 Realtek RTL8811AU 芯片组的 WiFi USB 加密狗。
我无法让它工作。我尝试了三种不同的驱动程序：
这里的司机：https://wiki.odroid.com/odroid-h2/application_note/howto_wifi_driver_rtl8812au
司机是这样的：
sudo apt install rtl8812au-dkms
早些时候，我看到它显示ip a为 enx200db03fa15e，但现在它已经消失了。
我附上了以下命令的输出：
lsusb
uname -a
lsmod | grep 8812
modinfo rtl8812au
mokutil --sb-state
sudo dkms status
journalctl -b | grep 8812
