First order of business for ASUS RT-AC66U routers
1). AiRadar (Beamforming) is in the pipeline scheduled for release for both ASUS RT-N66U and ASUS RT-AC66U. Why Beamforming? It's helps to enhances better coverage and WiFi connectivity.
2). As many are aware there isn't any new firmware updates since the ASUS .354, this is due to the resources are all been allocated to the development/stability/bug fixes of the new ASUS upcoming 5th generation AC WiFi routers firmware in preparation for the Computex Taipei 2013 product launches. Once the Computex Taipei 2013 show is over, we should be seeing the ASUS TW HQ firmware team back on track with the fixes/enhancements for both the ASUS RT-N66U/ASUS RT-AC66U.
