Hi, I live in Spain and have a fiber optic internet connection with Movistar... I recently got an Asus AC66U router and I want to use instead of the crap router included in the package from the ISP. (Comtrend WAP-5813n) However, it seems for a router to work with Movistar fiber it needs to support VLANs and 802.1q and 802.1p which it seems the latest official firmware from ASUS does not do. Does the asuswrt merlin address this issue? Does any other firmware compatible with Asus RT AC66U do this? I appreciate your help!
