Hello, everyone.

I'm not an expert. I'm asking you a question here because of OpenWRT.
R2S' Freemdly Firmware has no problem, but I wanted to use the pure original OpenWRT.

"Insufficient permissions to read UCI configuration"

But the problem is that the message bothers me.
I think it's an authorization problem, but after installing the OpenWRT firmware at first, which pack cage should I install next?

The hardware is R2S, USB WiFi Stick.
In the case of WiFi, it is a compatible product of Realtek company.

I would appreciate it if someone could tell me the installation order.
