1. WHAT’S CONCURRENT MODE This feature registers 2 wireles work devices in OS (wlan0, wlan1) and those two interfaces share the same hardware device. OS Wifi driver Wlan0 Wlan1 Realtek physical dongle/module This feature allows performing 2 separate wireless tasks at the same time with single hardware device. For example: The system can perform station mode to connect with an AP rou nd access inte , at the same time, it also perform the p2p connection with another p2p device and get the resource of this p2p device. Note: Realtek wifi only support 3 concurrent combination 1. Station mode + Station mode 2. Station mode + AP mode 3. Station mode + P2P mode 2. HOW TO ENABLE CONCURRENT MODE In Realtek wifi driver source code folder, edit “autoconf_chip_usb/sdio/pci_linux.h” to enable the definition of “CONFIG_CONCURRENT_MODE”, If there is no such file, edit the lude/autoconf.h, then rebuild and insmod the driver, done. You can verify if it works by ty “ifconfig –a” command, It is supposed to show two wireless interfaces, and MAC address of secondary interface is nearly the same except the bit1 of byte0 was assigned as 1. Base on the past experiences, we mend our s to verify whole system steps by steps – first check station mode, then check AP mode, finally station + AP mode (concurrent mode).  Please reference “ _cli_with_ _supplicant.pdf ” to understand how to run in station mode, “Quick_Start_Guide_for_Station_Mode.pdf” is also a good choice.  Please reference “Quick_Start_Guide_for_SoftAP.pdf” to understand how to run in AP mode. 3.
