WiFi Signal Strength Explorer

WiFi Surveyor turns data collected from RF Explorer spectrum analyzers into graphical charts and displays in real time, enabling users to more readily visualize the RF environment, monitor RF signals, troubleshoot RF issues, and detect sources of RF interference. Support for both 2.4x GHz and 5.x GHz scanning on devices with dual-band Wi-Fi radios. Site Survey View - displays each AP's beacon signal strength and channel. When monitoring the 2.4 GHz ISM band, this view also emphasizes how Wi-Fi channels overlap with one another. Mar 05, 2019 WiFi Wireless Signal Strength Explorer (was WiFi Signal Strength Status) allows you to see wireless signal strength right on the menu bar. See the status of your wifi signal strength right from the menu bar. This utility adds network name, signal strength with 'neat icon', 'percentage' on the menu bar. Mar 21, 2021 Thicker walls, such as those made of brick, concrete, or stone, seriously impact signal strength. You may also run into trouble if your walls contain metal ducts, studs, and pipes. If your walls are impeding the Wi-Fi signal, open the door to the room where your router is, and place the router is as close to it as possible.

Talking about 'good signal strength' may have become part of everyday language, but what constitutes a good Wi-Fi signal, really? Do you know what it takes to be able to use demanding services like Netflix and videoconferencing over Wi-Fi?

Signal strength is measured in dBm or decibel milliwatts, which, somewhat confusingly, is expressed only in negative values (with a minus sign in front).

So what are the good and acceptable dBm values for wireless internet?

Here is what the Wi-Fi signal strength values mean

How to measure the received signal strength

To measure signal strength at a given location and time, you can use a Wi-Fi scanner. You can read more about this in our article How to find good Wi-Fi channels and bad neighbors.

The measurement you are looking for is RSSI, which is short for received signal strength indicator.

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.


If you would like to map out the signal for an entire home, we recommend using a heat mapper to create a heat map of good and bad coverage zones. See also: Map your wireless network with a heat mapper.

Poor signal strength? Remove obstacles

Have you done your testing and concluded that the signal strength is insufficient? First of all:

Don't be tempted to try to amplify the transmit strength from your router / access point. You may sabotage both yourself and your neighbors in the process, and you risk breaking the law along the way. Read more about this in Don't. Boost. Your Wi-Fi Signal.

Calverter. Of course, the performance and capacity of the wireless network depends on more than the signal emitted from the access point, but the most important thing you can do for the signal is:

  • Move the router or other access point high up and in front of any obstacles. Preferably high up on the wall.
  • Place your devices and access points with as much of a clear line of sight between them as possible.
