rtw88-usb

This driver is forked from neojou/rtw88-usb, which is based on Realtek's rtw88 driver in Linux main trunk.

The driver supports Realtek USB wifi IC 88x2bu and 88x2cu, and supports at least managed (i.e. client) and monitor mode.

For a backport version (backport to kernel v4.15), please check this branch.

Build

$ make clean
$ make

Installation

Load driver for test:

$ sudo mkdir -p /lib/firmware/rtw88
$ sudo cp fw/rtw8822* /lib/firmware/rtw88/
$ sudo insmod rtw88.ko
$ sudo insmod rtwusb.ko

Load driver at boot:

$ sudo mkdir -p /lib/firmware/rtw88
$ sudo cp fw/rtw8822* /lib/firmware/rtw88/
$ sudo mkdir -p /lib/modules/`uname -r`/kernel/drivers/net/wireless/realtek/rtw88
$ sudo cp rtw88.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless/realtek/rtw88
$ sudo cp rtwusb.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless/realtek/rtw88
$ sudo depmod -a
$ sudo echo -e "rtw88\nrtwusb" > /etc/modules-load.d/rtwusb.conf
$ sudo systemctl start systemd-modules-load

General Commands

Scan:

$ sudo iw wlanX scan

Connect to the AP without security:

$ sudo iw wlanX connect <AP name>

Known Issues

• This driver doesn't support pcie. That means, loading this module will cause unpredictable results to other working Realtek wifi pcie device, especially to those laptops with Realtek wifi IC running kernel > v5.2.
