How to Measure Your WiFi's Signal Strength at Home (linksys)

JAKARTA, NETRALNEWS.COM - If you want to get more information on the power of your Wi-Fi network, you must use an application or program (such as the AirPort Utility or Wi-Fi Analyzer application) to measure the decibels relative to milliwatts (dBm).

You can measure Wi-Fi signals in various ways. The most accurate measurement is milliwatts (mW), but it is also the most difficult to read because the number of places is decimal (0,0001 mW).

The Received Signal Strength Indicator (RSSI) is another option, but Wi-Fi vendors handle it inconsistently and with varying scales. Decibels relative to milliwatts (dBm) avoid this problem, and many manufacturers convert RSSI to dBm.

As reported from the howtogeek page, the first thing to know is that dBm measurements will be displayed in negative numbers. The scale runs from -30 to -90.

If you look at -30, you have a "perfect connection," and chances are, you are standing next to the Wi-Fi router.

However, if you find a Wi-Fi signal listed at -90, this service must be so weak that you might not be able to connect to that network.

A very good connection is around the -50 dBm number, while -60 dBm is probably pretty good for streaming, handling voice calls, and others.

To measure the signal strength of Wi-Fi on your mobile or tablet, you can use the Airport Utility App for iPhone and iPad, or Wi-Fi Analyzer for Android. Both are easy to use and show results for wireless networks in your area.

For iPhone users, the Airport Utility App does require you to enter your device settings and turn on the Wi-Fi scanner. Just open your iPhone or iPad settings (not application settings), tap Airport Utility in the settings list, then turn off the Wi-Fi Scanner. Now, return to the Airport Utility application and start scanning. You will see dBm measurements expressed as RSSI.

Meanwhile, for Android users, Wi-Fi Analyzer is an easier step. Open the application and look for the network found. Each entry will be registered as dBm power.

The Android Wi-Fi analyzer and Airport Utility App for iOS show the strength of the Wi-Fi signal

Whereas in Windows 10 it doesn't have a built-in way to see the right signal strength, even though the netsh wlan interface command gives you the strength of your signal as a percentage.

In the past, you can use NirSoft WifiInfoView to check the Wi-Fi channel, and it's also good enough to check the power of Wi-Fi. This program is free, easy to use, and does not require installation. Simply unzip and double-click the EXE file. Like Mac and iOS, you will find dBm measurements listed under the RSSI entry.

On a Mac, you don't need to download any program or application if you want to measure the connected network. Hold down the option key and click on the Wi-Fi symbol. You will see the dBm measurement in the RSSI entry.
