I got Wi-Fi USB stick (from Aliexpress) with Realtek 8811 chip.
In Linux (Ubuntu 16.04) I turn USB mode from the CD-ROM with Windows setup program to Wi-Fi network card mode using usb_modeswitch.
And, of course I need to install driver itself.
1. Install driver rtl8821/8811:
- git clone https://github.com/brektrou/rtl8821CU.git
- cd rtl8821CU
- make
- sudo make install
2. Install sub_modewitch with patch:
- git clone https://gitlab.com/mikhailnov/usb_modeswitch.git
- cd usb_modeswitch
- cd usb-modeswitch-data
- sudo make install
- cd ..
- cd usb-modeswitch
- make
- sudo ./usb_modeswitch -W -v 0bda -p 1a2b
3. Restart desktop:
- sudo shutdown -r now
After the system kernel is updated, you need to reinstall the rtl8821CU driver.
- cd rtl8821CU
- make clean; make
- sudo make install
