Bought a second router. The first without problems out of the box works fully functional for six months. I took the same one - at the first attempt to connect to 5 GHz, this radio module fell off. It turned out to be a common problem with this router - then there were a lot of dances with firmware, as a result, 5 GHz worked only after uploading an alternative firmware.
