TP-Link Archer C20 v4 Build

Thank you! I will send a message to the developer. The measured power (about -60 dBm in 1m from the antenna) is much lower than obtained with the original firmware and the WiFi led does not light. But, anyway, the 5GHz support to this device is a good news, after so long time!

This is what I got:

Hello Gents,
I am a newbie, probably this will be obvious... I am experinecing the same unreliabilty on 2.4GHz wifi as mentioned earlier (after installing package 18.06.01). Is there any simple way to get rid of this? Should I install some extra packages or replace existing ones?
Your support is appreciated,

So 5.8Ghz work for now? if so, please share how to install them..
