I'm trying to power up my signal on my external network card (TP-LINK TL-WN722N) by changing the country region to BO which i know that allows up to 30 dBm signal and setting up everything correctly without any error but nothing happens and it still in Tx-Power=20dBm. As i saw in others when they run [iw reg get] they get a global only a global country and they're changing the power correctly but when i'm setting everything same the power stills to 20dBms.

When i run [iw reg get] except from my global country i get and one phy#1 as you see on picture and i think this is the problem. How can i resolve this?
