Wi-Fi router: why you should never set the power to maximum

In an attempt to achieve the greatest possible coverage, many users tend to set the Wi-Fi transmit power of their routers to the maximum value. However, a recent analysis conducted by Tanveer Singh, and reported by Tom's Hardware Italia, suggests that this practice may not be the most effective choice, indeed, it could prove to be a mistake. Reducing the Wi-Fi signal strength slightly, rather than leaving it at 100%, has been shown to improve the responsiveness ofsmartphone and smart TV in a home test. This counterintuitive result opens up new perspectives on managementofand home networks and on optimizing the performance of connected devices.

Why not push your router to the max

The common idea is that a stronger signal equals a better connection. While adequate transmit power is critical to ensuring stable coverage, pushing it to the limit can introduce unexpected issues. An excessively strong signal can cause interference not only with other devices on the same network, but also with nearby Wi-Fi networks. This can lead to increased latency and decreased connection stability, especially for devices that are at moderate distances from the router. Instead of extending range in a useful way, too strong a signal can saturate the radio environment, making it more difficult for devices to communicate effectively with the router.

The test that revealed the truth

Tanveer Singh conducted a home experiment to evaluate the impact of router transmit power on device responsiveness. The results showed that lowering the Wi-Fi strength from 100% to lower levels led to a tangible improvement in the performance of smartphones and smart TVs. In particular, latency is decreased, making interactions with devices more immediate. This suggests that, in many home scenarios, maximum power is not necessarily synonymous with optimal performance. The key seems to lie in a balance that allows clear and smooth communication between the router and connected devices, avoiding congestion and interference.

router power wifi transmission - Implications for home automation and connected devices

The implications of this discovery are particularly relevant for the world of home automation and for all those smart home devices that require a stable and responsive connection. Smart light bulbs, thermostats, voice assistants, and security systems depend on seamless communication with your router. If an overly strong Wi-Fi signal creates interference or latency, the performance of these devices could suffer, compromising the reliability of the entire smart home. Optimizing the router's transmission power, perhaps through targeted tests within your home, could therefore result in a more fluid and responsive home automation experience. It is essential to consider that the quality of the connection does not only depend on the power, but also on the ability of the signal to propagate cleanly and be received correctly by the devices.

Conclusions: a necessary compromise

In conclusion, the idea of ​​setting therouter power wifi transmissionto achieve maximum coverage is an approach that deserves to be reconsidered. Tests indicate that slightly reduced transmit power can actually improve the responsiveness of connected devices, reducing latency and interference. This is especially important in home environments densely populated with smart devices. The key to a performing Wi-Fi network lies in balance and optimization, rather than simply maximizing a single parameter. It is advisable to carry out tests in your home to find the ideal setting that guarantees both good coverage and a responsive connection for all devices.
