Since mobile phones can access the internet, the strength of a WiFi signal has long been considered a key indicator of quality of life. To improve this, people have explored various methods over the years. One popular technique involves using modified cans placed on the antennas of wireless routers to boost signal strength and enhance overall performance. This low-cost and easy-to-implement solution has gained popularity among many users.
After applying this method, users often report noticeable improvements in their WiFi signal—ranging from one to two bars, or even full coverage. Despite being an old trick, it still piques curiosity: can a simple aluminum can really make a difference?
Before conducting any real tests, we believed that this DIY approach might have some merit. The idea is to convert the router’s omnidirectional antenna into a more directional one by using the can as a reflector. In theory, this should concentrate the signal in a specific direction, leading to better coverage in that area.
However, strong signal strength doesn’t always mean faster internet speeds. A good signal allows the router to transmit data at higher rates, but other factors like interference and distance also play a role. So, while signal strength is important, speed and stability are equally critical.
For our test, we used a Xiaomi Router 3 with four antennas. To avoid interference, we disabled two of the 5GHz antennas and kept only one 2.4GHz antenna for testing. We set up two data collection points: one at 0.5 meters and another at 35 meters from the router, with three walls between them. This setup made the test more challenging but also more meaningful.
We measured signal strength, latency, and download speed both with and without the modified cans. After several trials, we found that while the signal strength at 35 meters didn’t change much, the latency improved significantly, and the number of dropped connections decreased.
Through multiple adjustments to the shape and angle of the aluminum can, we achieved better results. The most effective configuration involved stretching the can as far as possible and directing it toward the area needing improvement. While the benefits were modest, the transformation did show some real impact, especially in reducing disconnections.
Despite its effectiveness, this method requires time and patience, and the improvements in speed and signal are relatively small. It might be more suitable for those who enjoy tinkering or want to experiment with DIY solutions.
In conclusion, while aluminum cans can slightly enhance WiFi signal strength, the gains are limited. However, the process of creating a directional antenna is interesting and worth trying for enthusiasts.
