Top 3 Best Apps to Measure WiFi Signal Strength for Windows

Measuring WiFi signal strength to diagnose connectivity issues or improve your coverage is easy if you equip yourself with one of the best WiFi signal strength meter apps described in this article. While we focus only on Windows, there are also many great apps to measure WiFi signal strength on Mac.

Why download a dedicated WiFi strength meter when you can see how strong your WiFi connection is just by looking at the WiFi indicator icon in the taskbar? Because the WiFi indicator icon doesn’t tell you the full story.

Possible Reasons for a Bad WiFi Signal

The strength of your WiFi signal can be negatively influenced by a number of different factors, including:

• Physical obstacles: Like all other forms of wireless communication, WiFi signals have a limited ability to pass through solid physical obstacles. While less dense materials such as wood or foam shouldn’t affect your signal too much, concrete or metal is a whole different story entirely. While you might not always be able to avoid all large physical obstacles, you should at least try to keep your router away from them and use a WiFi signal strength app to measure the loss of your signal strength.
• Distance from router: The WiFi signal emitted by your router becomes weaker and weaker the farther away you get from the router. By measuring WiFi signal strength in different parts of your home or office, you can create a signal strength heatmap to visualize your coverage and see all areas of signal weakness at a glance.
• Signal interference: There are many electronic devices that emit electromagnetic waves in the radio spectrum (from 30 Hz to 300 GHz). Examples include baby monitors, garage door openers, kitchen appliances, walkie-talkies, security cameras, cordless phones, Bluetooth devices, and, of course, other WiFi routers. If you’ve ever attempted to have a deep conversation at a load party, then you can image how difficult it is for WiFi devices to communicate when there’s too much signal interference.
• Router settings: Modern WiFi routers support multiple bands (most commonly 2.4 GHz and 5 GHz), which are split into many different channels, some of which may be far busier than others. They also come with a whole host of performance-enhancing features, some of which may need to be manually enabled and configured.
• WiFi leeches: The term WiFi leeches is used to described people who search for unsecured networks using WiFi signal strength apps and other tools and connect to them without asking for a permission. The good news is that WiFi leeches can be easily repelled using strong encryption, which all modern routers support.

In the real-world, you can expect multiple factors to influence the quality of your WiFi signal at the same time, and the apps described in this article can help you understand them by measuring their impact and displaying the results in an easy-to-understand format.

Why Measure WiFi Strength and What WiFi Signal Strength Meter Apps Do?

When you set up a wireless network, the coverage is seldom even. Various obstacles, such as furniture and walls, weaken the signal as it passes through them, and so does interference caused by other wireless networks nearby. WiFi signal also gets progressively weaker the farther away it travels from the source (i.e., your router).

Only when you have a reasonably strong signal can you enjoy fast download speeds, lag-free Skype conversations, and web browsing without constant waiting for pages to load. To have a strong signal everywhere you need, it’s critical to choose an optimal place for the router and configure it in a way that will give the best results.

But selecting a good place for a router and configuring its settings is impossible without access to the right information. Namely, a visual map of the router’s wireless coverage and information about other WiFi networks in the area.

WiFi signal strength meter apps detect and analyze wireless networks, displaying information about their configuration and security, and some can also visualize the signal strength of wireless networks as convenient heatmaps, helping you decide where it would be best to place your router.

What to Know

• In Windows, go to Network and Internet >Network and Sharing Center. Select the blue Wi-Fi link to see the signal strength.
• On Mac, the Wi-Fi indicator is located in the upper-right corner of the screen in the menu bar.
• On Linux systems, use the following command: iwconfig wlan0 | grep -i —color signal.

This guide explains how to check Wi-Fi signal strength on a variety of platforms. These instructions apply to currently supported versions of Windows, Mac, Linux, iOS, and Android.

How to Measure Your Wi-Fi Signal Strength

The performance of a Wi-Fi wireless network connection depends on the radio signal strength. On the path between the wireless access point and a connected device, the signal strength in each direction determines the data rate available on that link.

Use the following methods to determine the signal strength of your Wi-Fi connection and find ways to improve the Wi-Fi reception of your connected devices. Different tools may show different results. These variations are caused by differences in how the utilities collect samples and the timing used to report an overall rating.

Network bandwidth isn’t the same as signal strength. Network bandwidth is the speed you get from your internet service provider (ISP). Signal strength determines the functionality of the hardware connected to the network and the range a Wi-Fi network typically has throughout an area.

Use a Built-in Operating System Utility

Microsoft Windows and other operating systems contain a built-in utility to monitor wireless network connections. This is the quickest and easiest way to measure Wi-Fi strength.

In newer versions of Windows, select the network icon on the taskbar to see the wireless network you’re connected to. Five bars indicate the signal strength of the connection—one bar is the poorest connection, and five is the best.

To find the network connection in modern versions of Windows, open Control Panel and go to Network and Internet > Network and Sharing Center, and select the blue Wi-Fi link to see the Wi-Fi strength.

On a Mac, the Wi-Fi indicator is located in the upper-right corner of the screen in the menu bar. One bar is the poorest connection, and three is the best.

On Linux systems, use the following command to display the signal level in the terminal window:

iwconfig wlan0 | grep -i —color signal

The output in terminal is displayed as a dB value. The more negative the value, the worse the signal strength. Anything from -50 dBm to -70 dBm is considered great to decent signal strength.

Use a Smartphone or Tablet

Any mobile device that is internet capable has a section in the settings that shows the strength of the Wi-Fi networks in range. For example, on an iPhone, open the Settings app and go to Wi-Fi to see the Wi-Fi strength of the network you’re on and the signal strength of any network that’s in range.

A similar method can be used on an Android phone or tablet. Look under a Settings, Wi-Fi, or Network menu. For example, in the settings on a Google Pixel with Android 10, select Network & internet, select the Wi-Fi you’re using, and then select the gear icon next to the network you’re connected to. There you can see the signal strength.

Another option is to download a free app such as Wifi Analyzer for Android, which shows the Wi-Fi strength visually in dBm compared to other nearby networks. Similar options are available for other platforms.

Open Your Wireless Adapter’s Utility Program

Some manufacturers of wireless network hardware or notebook computers provide software applications that monitor wireless signal strength. These applications report signal strength and quality based on a percentage from zero to 100 percent and additional detail tailored specifically to the hardware.

The operating system utility and the vendor hardware utility may display the same information in different formats. For example, a connection with an excellent 5-bar rating in Windows may show in the vendor software as excellent with a percentage rating anywhere between 80 and 100 percent. Vendor utilities can often tap into extra hardware instrumentation to precisely calculate radio signal levels as measured in decibels (dB).

Wi-Fi Locators Are Another Option

A Wi-Fi locator device scans radio frequencies in the local area and detects the signal strength of nearby wireless access points. Wi-Fi locators exist in the form of small hardware gadgets that fit on a keychain.

Most Wi-Fi locators use a set of between four and six LEDs to indicate signal strength in units of bars similar to the Windows utility. Unlike the above methods, however, Wi-Fi locator devices do not measure the strength of a connection but instead, only predict the strength of a connection.

To boost a Wi-Fi signal, try repositioning your router to avoid interference. You can also change the Wi-Fi channel numbers, update your router firmware, upgrade the antennas on your router, add a signal amplifier, use a wireless access point, or try a Wi-Fi extender.

Reset your Wi-Fi by restarting your router and modem. Unplug the router and modem and wait about 30 seconds. Then, plug in the modem and power it on. Wait 60 seconds, plug in the router, and power it on. Wait about two minutes before testing or using the devices.

To find your Wi-Fi password in Windows 10, navigate to the Network and Sharing Center, select Connections, and your network. In Wireless Network Properties, go to Security, select Show characters, and view the Wi-Fi password. On a Mac, access the Keychain Access app and select System > Passwords; double-click the network > Show password.
