Super router, easy to use the RT-AC56U

I have the RT-AC56U connected behind an O2 modem. Now I finally have a decent WiFi in my duplex. Currently the router is at one end of the apartment, since the telephone line is installed. I usually sit with my laptop (Asus N56VZ with Intel Dual Band Wireless AC 7260 - network adapter) directly next to it. However, if I go to another room I notice the difference immediately to the measly O2 router. 15m air line, a change of stage and 2-3 walls further I still have great reception. A WLAN Stick 1st Gerneration (56Mbit) can still loose stream a 720p movie using the router. Nevertheless, I will still replace the Fritz stick sometimes.
Even a short feedback to the operator Tung. Immediately after the initial installation, which ran insanely simple, I have carried out a firmware update, which was also very easy. Otherwise you just have time to invest a little time, then it is also possible settings, such as IP allocation, WLAN off at certain times ... find.

All in all a great device
