I have several routers running an openwrt variant. Some are based on the MT-7622, the MT-7621 and broadcom based routers. My WiFI Kit32 connects flawlessly in under 5 seconds to both the MT-7621 and the broadcom based routers, but has issues connecting with the MT-7622.
Hostapd will report

It might connect eventually (minutes later) or it might not at all.
I’ve also tried the same tests with a WiFi Lora kit as well as several esp33’s and esp8266 boards, they all connect fine to the MT-7622.
Has anyone else seen this behavior?
