Channel 9 implies that this is a 2GHz band access point, which by definition cannot provide wifi 5 (11ac) because 11ac only exists in the 5GHz band. There could be APs on channel 36 and above which might provide 11ac. Search the output of ifconfig iwm0 scan to find them. If auto-selection doesn't prefer 5GHz (it usually should) then you could pin the interface to a specific channel or bssid with ifconfig.
