Mr6400 poor wifi range on openwrt 23.05.4

i recently installed openwrt 23.05.4 on my tplink mr6400 v5 and i get very poor wifi range on any dbm power level max level is 79 miliwatts wifi power but on stock the wifi range is good how can i get a wifi range as good as stock

Configure a country for the wifi ? Without it transmission power is absymal.

The wifi region is set to HU Hungary is the country where i live.
