The higher this number is, the better the WiFi connection. Ideally, you want to have a high SNR ratio. Simply subtract the value of “Noise” from the “RSSI” value to get the SNR value.įor example, channel 13 has an RSSI of -49 and the noise is -95. This is called the “SNR,” which stands for “Signal-to-Noise Ratio.” To complete the calculation, we want to measure the difference between these two values. Again, because these numbers are negative, the lowest number would be the one that’s farthest from zero. On the other hand, for “Noise,” you’ll need to look for the lowest number. For example, an RSSI of -45 is better compared to an RSSI of -70.

But, because they’re negative, it’s important to remember that “higher” will mean as close to zero as possible. In this case, “Noise” stands for the number of other signals that might interfere with the signal being monitored.īoth values are always in negative numbers.įor RSSI, you’ll have to check for the highest number (the higher, the better). Noise, also “Noise Floor,” is the sum of all the noise sources and unwanted signals within the connection range. RSSI stands for “Received Signal Strength Indicator.” It tells you how strong the connection between your device and a router is. When you want to find the best WiFi channel, you’ll have to consider two important numbers. Then, I’ll instruct you on how to set up your WiFi router in order to tune into that channel.

In this step-by-step guide, I’ll show you how to improve your WiFi connection by finding the best WiFi channel for your router, for both PC and cell phone. In order to get the best possible WiFi connection in your area, you’ll have to switch to a channel that either has no other users (or significantly fewer users) than the current channel you’re using. These issues are often caused by the large number of people attempting to connect to the internet, causing an overload of wireless signals using the same network channel. That said, if you live in an apartment building or densely populated area, you might experience frequent network timeouts, disconnection issues or an overall slow internet speed.

Your router’s wireless access point is connected to a certain channel, which connects you to a WiFi network. N owadays, pretty much everyone has a wireless network connection setup at home.
