TL-MR3020 v3 WiFi + LED problems

Hello,

I'm compiling my own build with custom files in it. I've chosen Tp-Link MR3020-v3 as target profile and everything works fine except for continuous network blackouts. When connected to WiFi the net goes dark and then comes back, I experience it repeatedly on multiple devices.

Also, only the power led turns on. No other leds are working.

I can use default firmware and then scp custom files to it but it'd be more convenient for me to build the image from scratch with files in it.

What's the possible solution here? How should I proceed?

Thank you.

Knowing what that means and what the logs show would help give others more insight into your problems.
