Your best WIFI settings are the defaults. Including the use of Dual Band SmartConnect.

We are all entitled to our opinion. I was expressing mine ...Your advice doesn't work well in Europe to begin with. Default settings are far from the best and Smart Connect plus Auto channel jumping in 2x DFS regions with different power limits is a disaster. When you see "including channels 12, 13" in WebGUI options this router is clearly very different than yours in North America and is working in very different Wi-Fi environment. Your experience doesn't apply. Some say details are important.
The engineers above copy/paste invented Explicit Beamforming and MU-MIMO on 2.4GHz band up to 802.11n... forgot to invent clients for it.
