Strong signal strength results in more reliable connections and higher speeds. Signal strength is represented in -dBm format (0 to -100). This is the power ratio in decibels (dB) of the measured power referenced to one milliwatt. For example, -41dBm is better signal strength than -61dBm.
Is Lower dB better WiFi?
Wireless signal strength is measured in dBm (decibel milliwatts) and is, somewhat confusingly, expressed only as negative values. Anything down to this level can be considered excellent signal strength. -60 dBm. Good, reliable signal strength.Wireless signal strength is measured in dBm (decibel milliwattsdecibel milliwattsdBm or dBmW (decibel-milliwatts) is a unit of level used to indicate that a power level is expressed in decibels (dB) with reference to one milliwatt (mW).https://en.wikipedia.org › wiki › DBmdBm - Wikipedia) and is, somewhat confusingly, expressed only as negative values.

Can a Wi-Fi signal be blocked?
In theory, Wi-Fi signals are capable of passing through walls and other obstacles relatively easily. However, in reality, some walls are thicker or use reinforced concrete and may block some of the signals. Materials such as drywall, plywood, other kinds of wood and glass can be easily penetrated by wireless signals.
What kills Wi-Fi signal?
Anything that has metal, such as metal blinds, doors, furniture, infrastructure, and walls, can greatly diminish or completely eliminate the WiFi signal. The more metal there is between your WiFi router and the connected device, the worse the WiFi signal will be.6 Jan 2021
