How to enable WIFI on ASUS RT-AC68U?

When I was looking for an option to enable wireless network I couldn't find it, but after some research I realized the WIFI option was actually missing from the Network category in LUCI. Can I enable wireless in some other way? If so how do I do it? I am very new to custom firmware on routers but I heard good about it and I didn't really like the sophisticated feeling of ASUS stock firmware.

Thanks in advance //
