Good wifi router for mac6/26/2023 In this case, “Noise” stands for the number of other signals that might interfere with the signal being monitored.īoth values are always listed as negative numbers.įor RSSI, you’ll have to check for the highest number (the higher, the better). But, because they’re negative, it’s important to remember that “higher” will mean as close to zero as possible. For example, an RSSI of -45 is better compared to an RSSI of -70. On the other hand, for “Noise,” you’ll need to look for the lowest number. Again, because these numbers are negative, the lowest number would be the one that’s farthest from zero. 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. 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. Ideally, you want to have a high SNR ratio. The higher this number is, the better the WiFi connection. If you’re into manual calculations, that’s cool, you do you. However, for those of us who majored in something besides math, there are WiFi channel apps that will do the math for you and tell you which channel is best.
