RouterOS 7.18 fixed everything for me, recommend to UPDATE IT ASAP, the configuration is exactly the same as 7.15.3, but now it oprates even better, it connects devices correctly as AX and AC, not the A/N weird connection
Just use the same configuration as the first post, it works perfectly now, with no extra steps
