@825i Increasing Tx Power leads to more noise, it may/may not increase performance. It's basically aim is to increase the range of your router. However, this could also increase heat and load.
If I'm not mistaken, the
txpwr_target_max
key only indicates the maximum allowed Tx Power, it doesn't increase the value. It's a dynamic value based on the selected country, etc.Thanks for posting your findings and results. Like said in the disclaimer, it may work for you or not.
In most cases unfortunately it doesn't work, because many WiFi-chipsets have hidden/unknown abilities to check if the receiving/sending values are valid. So even changing the country or Tx Power, it may not change anything to your end-devices.
