Remains positive that the router what power and performance terms otherwise easily performs its service: No Burglaries in the wireless speed even during long transfers or crashes during extended operation and not only against the wireless card I get good speeds but also against the iPad Air in the 5 GHz band, the full 5 MB / s. of my VDSL The 2.4 GHz band is only about 4 MB / s with more than ten other active radio networks.
You can actually configure everything you need and more via the web interface, only there are little things throughout the cloud the overall impression a bit. Example Firmware Update: It frequently updates (good!), But find yourself doing this even if the router newer exist despite additional function for not. Then you can save the settings prior to the update, but after that, if you should reset the router like last update, replay not directly but must first go through the initial setup again. No major flaws, but the overall impression then tarnishing that the file selection for the firmware and settings file not all other files are hidden with other endings.
Even otherwise, many menus are generally nested confusing or individual settings are not necessarily where they are suspected and the display of the connected wireless clients and properties as their signal strength are shown very confusing.
In my eyes, the RT-AC56U a class router is, once properly configured easily and quickly does its job. Only if you want to configure something via the web, it is a bit uncomfortable.
