Configuring as access point, openvpn and guestmode

[earth08]

i have install sqm,
one thing
i cannot connect to AdGuardHome DNS connected to second router from my main router connected device, which makes my ssid from 1st router with dns to device attached to second router doesnt connect to internet

one more thing, as i have stated earlier i have installed miwifi nano snap 19.072 on my miwifi 3c.

Support for Xiaomi MiWiFi 3C

one problem is, it works slow on openwrt device as compared to stock, and padavan. I am using it as wire connected repeater. one more problem dont know, it might be because of interchanged wan lan or my settings, I cant connect to my devices connected to second router ( repeater- miwifi 3c -openwrt installed).

I have my config as
