On many new routers, especially mesh platforms like the eero and Google Nest Wi-Fi, you won't even find options for fiddling with transmit power. Not only that, but with each new generation of the Wi-Fi standard coupled with updated routers that take advantage of protocol improvements and additions, your router simply does a better job. Maybe back in the 2000s and even into the early 2010s, when consumer routers were a little rougher around the edges, you needed to get under the hood and tweak things.īut even back then, and more so now, the firmware on your router can handle adjusting the transmit power on its own. Your Router Likely Adjusts the Power Better You'll have a superior experience if your home is blanketed with Wi-Fi from multiple lower power access points than turning the power on a single access point up all the way. While broadcasting music and broadcasting a Wi-Fi signal isn't directly analogous in every way, the general idea translates pretty well. Ideally, you'd want a whole house audio solution with speakers in every room so that you could enjoy the music without distortion. But you'd quickly find the sound was distorted and the listening experience wasn't uniform. You could do so by setting up a stereo system with large speakers in a single room and then turning up the volume high enough that you could hear the music in every room. To use the volume example again, let's say you wanted to pipe music throughout your entire home. Raising Transmit Power Can Decrease PerformanceĬounter-intuitively, cranking up the power can actually lead to decreased performance. There are much better ways to address your Wi-Fi problems, which we'll discuss in the next section. Given that increasing the transmit power doesn't automatically equal a better experience, it's not really worth decreasing the Wi-Fi quality for all your neighbors just to, theoretically, get a marginal performance increase in your home. If your home is close to other homes also using Wi-Fi, be it tightly packed apartments or just a neighborhood with small lots, cranking up the power may offer a small boost for you but at the expense of polluting the airspace all around your home. Raising Transmit Power Increases Interference Your phone can "hear" the tower, but it struggles to talk back. This is not unlike when you're using your cellphone in an area with poor coverage, and while your phone says you have at least a bar of signal strength, you're unable to make a phone call or use the internet. This means there will come a point where the client is close enough to the Wi-Fi router to detect the signal but not strong enough to talk back effectively. The router is much more powerful than the device it is paired with unless the other device happens to be another access point with equal power. Generally speaking, the power level between the Wi-Fi router and the clients the router is communicating with, however, is asymmetric. 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, 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.
