It's sending out a signal and expecting one back. Your Wi-Fi router isn't just blasting out a signal into space to get picked up passively, like a radio listening to a distant radio station. Your Router Is Powerful Your Devices Are Not And others offer an absolute setting corresponding to the milliwatt output of the radio, usually labeled just mW (not dBm,) with whatever range is available for the hardware, such as 0-200 mW.Īnd, if your home is significantly separated from your neighbors by acres (or even miles) of space, then by all means, feel free to play around with the settings as you won't be helping or hurting anybody but yourself.īut for the majority of people, there are more than a few very practical reasons to leave the router settings as they are. Others offer a menu with relative power, allowing you to adjust transmit power anywhere from 0% to 100% power. Some have a simple low, medium, and high option. Depending on the manufacturer and model in question, it might be labeled Transmit Power, Transmit Power Control, Tx Power, or some variation thereof. How the transmit power is displayed and adjusted varies between manufacturers. If your router allows for transmit power adjustments, you can turn the volume up or down, so to speak, in the configuration panel to increase the power output. Much like sound energy is measured in decibels (dB), Wi-Fi radio energy is measured similarly with decibel milliwatts (dBm). The transmit power of your Wi-Fi router is like a volume knob on a stereo. While there's undoubtedly an entire doctoral program and then some worth of information about radio transmission power and everything that goes along with it to share, in service of getting to the useful day-to-day stuff, we'll keep it brief here.
