Which technique can help improve Wi-Fi coverage?

Implementing signal boosters is a practical and effective technique for improving Wi-Fi coverage. Signal boosters, also known as Wi-Fi extenders or repeaters, amplify the existing Wi-Fi signal, allowing it to reach areas of the building or environment where the original router's signal is weak or nonexistent. By extending the range of the Wi-Fi signal, these devices help ensure that more areas can benefit from a reliable internet connection, which is particularly useful in larger homes or spaces with obstacles that obstruct the signal.

Using outdated routers would typically hinder the performance and range of the Wi-Fi network, as older technology may not support the latest standards or features that enhance coverage. Decreasing network access points usually results in less coverage rather than more, as it reduces the number of areas where the Wi-Fi signal can be transmitted. Separating devices on different networks might help manage bandwidth or reduce congestion, but it does not inherently improve coverage; instead, it could lead to having low coverage on one network while having adequate coverage on another. In contrast, implementing signal boosters directly targets the improvement of Wi-Fi reach and strength, making it the most effective approach in this context.
