My FP3 doesn't like higher 5Ghz Wifi channels, especially channel 116

Hi everyone, when I wanted to transfer a larger file from my NAS to my FP3 I was surprised by the low speed. I then found out that it was only connected to my 2,4Ghz Wifi, not the faster 5Ghz one (my FRITZ!Box 7560 router is providing both frequencies, with the same SSID). Normally the phone should auto-select the better one. Anyway, after forcing the FP3 to 5Ghz only, I was even more surprised (in a very negative way) that the phone could barely keep the connection stable. Speed was abysmal…
