Here are some guidelines for assessing your signal strength: Moreover, a 10 dBm change adds up to ten times more or less strength. In addition, signal strength isn’t linear it’s logarithmic, which means that every 3 dBm change represents a halving or doubling of the strength of the signal. For example, -80 dBm is a much weaker connection than -30 dBm. In other words, the larger the absolute value, the weaker the network connection.
