It’s a little unclear whether you should expect 12-13-14 to work in the US (see https://en.wikipedia.org/wiki/List_of_WLAN_channels and https://www.duckware.com/tech/wifi-in-the-us.html#24g - but of course use your judgement re: how authoritative those are…)
(update - it might be your hub not supporting those channels based on regulatory settings)
Yet another reason I really wish WF supported 5GHz for the hub. The 2.4 GHz spectrum is simply a mess in many locations.
