Good router for the price, but with a tinge of disappointment

For the money, you really can not say anything, good coverage, interface ok (would be nice if one could see as in the Fritzbox the wireless assignment of the channels, or who is connected, if you do not use the internal DHCP).
However, a major shortcoming for me is that only channels 36 to 48 can be used in the 5GHz band. This can Fritzbox better because there are many more (allowed) frequencies. Unfortunately, the most recent firmware update not helped here (3.14.1 Build 141126 Rel.62171n). If the 5 GHz band is so full time, which slows down tremendously.
I tested the Wi-Fi router with a T4U stick from the same house and come in a relatively short distance to 750-866 Mbit / s (without walls or furniture in between). In addition, I have a Repeater by AVM (300N / G) and is very stable at 2.4 GHz. In the hope that eventually all channels registered in Germany to come in the firmware, I give four stars.
Incidentally OpenWRT has unfortunately not helped to get more channels, was therefore back to the original firmware down gegraded.
