Here's a few wl commands you won't find on the help screen -

wl ap_isolate
(0/1) if enabled clients cannot see other clients on the same AP

wl maxassoc
wifi driver handles up to 128 connections; you can set the limit lower to enhance security: wl maxassoc 6
(or just make it easier to DoS)

wl -i wds0.49153 wds_remote_mac
returns the bssid of the remote endpoint

wl -i wds0.49153 wds_wpa_role
authenticator/supplicant

wl sup_wpa
(0/1) if the builtin supplicant is enabled this returns 1
(/sbin/wifi will automatically enable this)

wl wdstimeout
?? idle timeout on wds connections ??

wl rand
random number generator (useless?)

wl abbfl
wl abminrate
wl cram
wl eirp
wl scb_activity_time
wl sup_auth_status
wl txc_policy
