mt7612-for-mt7621-linux-4.14.167 loads but can't connect

[SteveChristianson]

I have built firmware openwrt-ramips-mt7621-zbtlink_zbt-we3526-squashfs-sysupgrade.bin from 19.07.1 using the 4.14.167 mt7612 drivers.

Firmware builds and I can flash on my router. The router comes up with no Wireless as I have removed the open source mt76 drivers from my build.

I can successfully bring up the native mt76 driver using

modprobe mt7612
ifconfig rai0 up

ifconfig -a shows the rai0 interface created after modprobe.

The logs seem to show the link is up

Wed Jan 29 16:40:48 2020 user.debug : mt7612_up called!
Wed Jan 29 16:40:49 2020 user.debug : add rai0 into lan
Wed Jan 29 16:40:50 2020 daemon.notice netifd: Network device 'rai0' link is up

I see the wifi-mt7612 SSID from my device. When I try to connect to the WiFi I get the error

Can't connect to this network

I believe the WiFi security is set up correct and working since if I enter an incorrect password for the SSID I get an error saying the password is incorrect. Entering the correct password gives me the error saying can't connect to network.

Is anyone else seeing an issue like this? Any suggestions on things I may have missed when building or starting WiFi? Maybe I missed some packages that need to be removed from stock openwrt WiFi. I see no evidence of old wlan0 or wlan1 from openwrt WiFi that is usually available from stock firmware.
