1. Introduction
The RT3883 SOC has the capability of working RT3883 and RT309x/RT539x wireless interfaces
concurrently.
A.

The interface1 (ra0): RT3883 (5G)

B.

The interface 2 (rai0): RT3090/RT5392 (2.4G)

Station can associate and execute WPS connection for any wireless interface. Moreover, user can
configure the settings of any wireless interface by Web GUI.

3. Usage
If the firmware is built successfully, you can upgrade it into your RT3883 reference board by TFTP Server
or Web GUI.
After firmware upgrade, you can use “lsmod” and “ifconfig” commands to check if RT3090_ap is
successfully inserted and brought up or not.
2nd WiFi interface module: RT3090_ap / RT5392_ap
RT3883 interface name: ra0
RT3090/RT5392 interface name: rai0

t

RT3883 profile is located on /etc/Wireless/RT2860/RT2860.dat and RT3090/RT5392 profile is located on
