It's under GPL license, and please feel free to use it. Also welcome to upstream to the Linux kernel if you want, and please refer to the branch, for_kernel_upstream, which meets the Linux coding style, and may be easier to upstream.
Thank to many people's kind help on this project.
Driver for 802.11ac USB Adapter with chipset: RTL88x2BU / RTL88x2CU
supports at least managed (i.e. client) and monitor mode.
This driver is based on Realtek's rtw88 driver in Linux main trunk.
A few known wireless cards that use this driver include
$ make clean
$ makeLoad driver for test:
$ sudo mkdir -p /lib/firmware/rtw88
$ sudo cp fw/rtw8822* /lib/firmware/rtw88/
$ sudo insmod rtw88.ko
$ sudo insmod rtwusb.koLoad driver at boot:
$ sudo mkdir -p /lib/firmware/rtw88
$ sudo cp fw/rtw8822* /lib/firmware/rtw88/
$ sudo mkdir /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-loadScan:
$ sudo iw wlanX scanConnect to the AP without security:
$ sudo iw wlanX connect <AP name>$ sudo ip link set wlanX down
$ sudo iw dev wlanX set type monitor
$ sudo rfkill unblock all
$ sudo ip link set wlanX upThen you can use "iw info" to check if the wireless mode is correct.
e.g.
wlan1 IEEE 802.11 Mode:Monitor ... And you can use the program like wireshark to sniffer wifi packets.
- set up the sniffer channel
$ sudo iw dev wlanX set channel xxx- run the program
$ sudo wiresharktest ok with general commands with the latest kernel ubuntu 18 + kernel v5.3 test with Network Manager ok.
- Currently, this driver is not upstreamed to Linux kernel driver rtw88 yet. 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.
