Have you done your testing and concluded that the signal strength is insufficient? First of all:ĭon't be tempted to try to amplify the transmit strength from your router / access point.

If you are running Mac OS X, you can also measure the received signal strength directly without installing anything: Hold down the Altkey and click the Wi-Fi icon in the top menu, and details of communication with the wireless access point will appear under the name of the active Wi-Fi network. The measurement you are looking for is RSSI, which is short for received signal strength indicator.

You can read more about this in our article How to find good Wi-Fi channels and bad neighbors. To measure signal strength at a given location and time, you can use a Wi-Fi scanner. How to measure the received signal strength It is very unlikely that you will be able to connect or make use of any services with this signal strength.

You cannot count on a reliable connection or sufficient signal strength to use services at this level. Minimum value required to make a connection. The signal is not very strong, but mostly sufficient. Video streaming/streaming (not the highest quality) This is the minimum value for all services that require smooth and reliable data traffic. This is still good, reliable signal strength. Maximum signal strength, you are probably standing right next to the access point / router.Īnything down to this level can be regarded as excellent signal strength. So what are the good and acceptable dBm values for wireless internet? Here is what the Wi-Fi signal strength values mean Signal Strength Signal strength is measured in dBm or decibel milliwatts, which, somewhat confusingly, is expressed only in negative values (with a minus sign in front).

This is the lowest possible value that will make a connection between the router and computer, but it's too weak to be useful for any online service. This is the lowest value that will deliver acceptable results for most online services. Anything from -30 dBm to -50 dBm is excellent and is often about as high as you can get. This is the maximum signal strength you could achieve, and it probably means you are within a couple feet of the Wi-Fi router. 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.
