Hi Rafal As you have mentioned I have looked up for my wifi hardware , it is supported by brcmfmac. I am using Ampak AP6212 wifi hardware which is listed as part of brcmfmac following link: http://linux-sunxi.org/Wifi I have inserted the brcmfmac module manually using modprobe but my wlan0 interface is linked with bcmdhd when I removed it I don't see wlan0 in ifconfig and when i re-insert it again and starts hostapd, it starts but it didn't broadcast the ssid and afterwards I tried to re-insert bcmdhd with op_mode=2 and starts hostapd again and it displayed the ssid this time (which i am currenly doing) It means hostapd is directly communicating with bcmdhd ,what does it has to do with brcmfmac Moreover on the given link they didn't provide the name of the driver ap6212 is using. but it follows brcmfmac mainline kernel.
