How to scan for and connect to APs? (FireWRT's OpenWRT)

I have a default build of the FireWRT from the git repository. The default access points are visible, but I want to test the radios as a client.

First, I cannot seem to scan for networks:
“iwlist scanning” says operation not supported for all the interfaces (ra0, rai0, apcli0, apclii0)
“iwinfo scan” says scanning not possible
“iwpriv get_site_survey” returns no results even though there are results.

How can I scan for networks properly? Am I missing some step?

Secondly, how do I actually connect to an access point? I have the below in /etc/config/wireless:

config wifi-device mt7602e
option type mt7602e
option hwmode 11n
option htmode HT40
option channel 6
option mode 9

config wifi-iface
option device mt7602e
option ifname ra0
option network lan
option mode ap
option ssid FireWRT-2.4G-B22A
option encryption psk2
option key firefly2015
option ApCliEnable 1
option ApCliSsid SM-N900VC38B
option ApCliAuthMode WPA2PSK
option ApCliEncrypType AES
option ApCliPassword MyPassword

Then I tried both /sbin/wifi and ifconfig apcli0 up; neither actually associated to the access point.

How do I connect?

MTK wifi driver not support scanning APs.
if you need it , please use "kmod-mt76 ".
