Transmit Power sets the TX power of the radios.

• A higher transmit power means longer range, higher signal-to-noise, and higher throughput.
• Higher power levels can also increase interference, so it is a balancing act.

• 2.4 GHz signals travel further, and through obstructions like walls or trees more effectively than 5 GHz or 6 GHz signals.

• 5 GHz signals weaken more rapidly and are more affected by obstructions, resulting in around half the range of 2.4 GHz.

• 6 GHz signals weaken even more rapidly and are even more affected by obstructions, resulting in less range than the 2.4 GHz or 5 GHz.

Use the lowest power level that still results in good coverage and signal strength.

• Keep 2.4 GHz around 6 dBm lower than 5 GHz or 6 GHz in multi-AP networks, to keep their coverage area roughly the same.

• 2.4 GHz: Set to Medium.
• 5 GHz: Set to High.
• 6 GHz: Set to High.
