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.

NetSpot is our favorite WiFi signal strength meter app because it combines simplicity with powerful features at an affordable price. NetSpot is both a WiFi signal strength visualizer and a WiFi discovery and analysis tool. Changing between these two distinct modes of operation is as simple as flipping a switch, and the same ease of use is characteristic for the rest of the software.
  • Inspector Mode

    Gives you real-time insights into the WiFi networks around you.
  • Survey Mode

    Provides a comprehensive, map-based analysis of your WiFi network's performance.
  • Planning Mode

    Enables you to simulate and plan your WiFi network's layout and coverage.

To draw a WiFi signal strength heatmap with NetSpot, you first have to supply NetSpot with a map of the area you want to visualize. You can either upload an existing map or create one from scratch. With the map ready, you walk from one place to the next until you’ve measured WiFi strength everywhere. NetSpot then analyzes the gathered data and turns it into a signal strength heatmap.

A tool like this is useful for finding the best open WiFi network in public places or for basic troubleshooting. WiFi Analyzer is available in Windows Store for free.

choice #3
Available for Windows, Linux, OS X, Solaris, FreeBSD, NetBSD, and many others

In many ways, Wireshark is the polar opposite of WiFi Analyzer. Just like NetSpot, Wireshark can satisfy the needs of network professionals, but it largely disregards the needs of beginners. Wireshark can analyze wireless network traffic down to individual packets, which is why it’s widely used by software developers and by security experts doing penetration testing.


Don’t expect to know how to use it without reading the manual, though.

The best WiFi signal strength

So what signal strength should you be content with? It depends on the tasks you expect to be fulfilled. For example for sending and fetching emails, browsing the Internet, or scanning barcodes, -70 dBm is a decent signal strength. If you are going to use higher-throughput apps, -67 dBm is more suitable. Some engineers will recommend -65 dBm if you are are interested in supporting mobile iOS or Android devices.

Note: The values in the chart below are suggestions. Depending on the requirements of a real-life network the desired WiFi signal strength will vary.

>-50 dBm Excellent Values around this can be considered an outstanding signal strength.
-50 dBm to -60 dBm Good A signal strength good enough for task of any level.
-60 dBm to -70 dBm Fair The minimum value for any service dependant on a steady connection and signal strength, e.g. voice over Wi-Fi or non-HD video streaming.
<-70 dBm Weak This value of signal strength is considered unreliable and won't suffice for most services

How to Increase WiFi Signal Strength?

One Google search is enough to find dozens of tips and tricks how to increase WiFi signal strength. Some are nonsensical, some give questionable results, and some are legitimate. Most of them, however, have something to do with either router placement or router configuration.

  • Where you place your router matters a lot, as any WiFi signal meter app, such as NetSpot, can reveal. You want to give your router some space to breathe. Don’t place it too close to walls or other large obstacles.
Select a Good Place for Your Router
  • Consider the area you want to cover with a WiFi signal and place the router as close to the center of the area as possible for even signal distribution. If your signal is still weak, consider placing the router somewhere higher, such as on a shelf. Use NetSpot or another similar WiFi signal strength meter app to measure whether you’ve picked a good spot.
Understanding the Information Signal
  • Once you’re satisfied with the placement of your router, it’s time to fire up the admin user interface and change a few settings. Start with security settings. Pick a strong password and use WPA2 encryption to protect yourself against hackers and people looking for free WiFi access.
  • Then, open NetSpot or other WiFi signal strength app and see which channel other wireless networks in your area use. To avoid interference, you want to configure your router to use the least cluttered channel. Luckily, this is as easy as changing one setting.
