@frank-w thank you for explanation, I’ll try to do things right.
@niebieski20 thanks for the advice. Manually specifying country in /etc/config/wireless did have some effect. mt7622 responds to country code change but mt7615 doesn’t. mt7622 won’t go past 25 dBm and mt7615 is stuck on 16 dBm. I’ve tried ‘US’, ‘AU’ and ‘RU’ domains.

I still think there is some limitation in eeproms. I found eeprom bytes meaning in mt76x02_eeprom.h and in mt7615/eeprom.h files. Seems like I need to change some bytes in eeprom to unlock mt7615 card’s full potential.

I’ve tried changing MT_EE_COUNTRY_REGION_5GHZ and MT_EE_COUNTRY_REGION_2GHZ bytes in mt7615e.eeprom.bin from 0x01 to 0x00 but that had no effect on 16 dBm limit. Maybe @Ryder.Lee could help with these settings?
