Apparently the AP refused association because the client's request does
not meet the basic rate set requirements (status 18).

qwx works fine on my 11ac AP in 11a mode. This driver does not yet
support 11n/11ac modes, and adding such support will require a big
chunk of further development time, it won't be ready for 7.5.

Does your AP have support for "legacy 11a/b/g" clients disabled somehow?
Some APs advertise such options for performance in their config and may
need to be disabled to make it work.

Can you please show a beacon of this AP?

One line from tcpdump this command while trying to associate to the AP should
suffice:

  tcdump -n -i qwx0 -y IEEE802_11_RADIO -s 1500 -v wlan host 20:c0:47:bb:bc:4c

I am looking for the field which lists the supported rates:

   ... rates 6M* 9M 12M* 18M 24M* 36M 48M 54M, ...
