SET PowerTX Wifi Card

Good evening,
I installed on the TP-Link TL-WDR3600 v1 the version OpenWrt 19.07.2 r10947-65030d81f3 / LuCI openwrt-19.07 branch git-20.094.46635-de52000 and I wanted to increase the wifi power to 30dbm. That was the case with the old version.
Currently 2.4Ghz max 22dbm and 5Ghz max 19dbm
There is a solution ?

Which version exactly?

Are you sure your wifi operates with a legal transmit power if it will be set to 30dbm?
Beside this, i don´t think the device can really provide 30dbm (1000mW) transmit power because of hw limitations.

With the 12.x version it was like that and the wifi signal also arrived in the kitchen.
Increase it to 27 too?
