Whenever you go online you most probably do so through WiFi. Because wireless networks are so popular it makes sense to ensure the top performance with efficient WiFi analyzer tools.

So what are those WiFi analyzer apps and how does one use them? A WiFi analyzer app detects all available WiFi networks around and should provide you with detailed info on every network it found. You should be able to see which channels networks use, the signal strengths, WiFi encryption methods used, etc.

Why can it be rather useful to know which channel a wireless network operates on? Because in a WiFi crowded space, where every neighbor has their own network, overlapping channels is the most common reason of a slower connection. When you figure out which channels are the least crowded and switch to one of those you'll see the immediate difference in your WiFi performance.

Why Do You Need a WiFi Analyzer App?

Whether it's for home or office use, a robust WiFi analyzer app is a game changer for anyone looking to optimize their WiFi network. Now, you may be wondering, what's the big deal with WiFi analysis? Well, it's simple — an efficient WiFi spectrum analyzer for Mac will help you select the most fitting WiFi network and the most effective WiFi channel for your router.

High-quality Mac WiFi analyzer tools have the possibility to create accurate WiFi signal strength heatmaps, where you'll be able to clearly see and analyze the areas with the strongest, not so strong, and the weakest signal and decide how you can mend the issues.

Let’s take a look at some situations when Mac WiFi analyzer tools come in handy:

  • Finding the sweet spot for your router: It's all about location, location, location! A WiFi analyzer for Mac can help you determine the best position for your router to maximize its signal reach.
  • Poor performance: No one likes a slow internet connection, especially when you're streaming your favorite show or on an important video call. Several factors could lead to slow loading websites, and WiFi analyzer tools can pinpoint the root of your performance issues.
  • Unreliable connection: It's a WiFi jungle out there, with several networks potentially clashing and causing interference. Many WiFi reliability issues are due to signal interference from other networks in your area. Luckily, a good mac WiFi analyzer can tell you which frequencies and channels are the most crowded, so you can choose a less congested one for a smoother connection.
  • Scouting for free WiFi: When you're out and about, finding a stable free WiFi can be a lifesaver. With a capable WiFi analyzer app, you can discover hidden networks and assess their security settings, ensuring you stay connected without compromising your security.

The best part is, there's a variety of WiFi analyzer apps available to suit your specific needs — from a basic free WiFi analyzer for Mac to more advanced ones, like NetSpot's WiFi Spectrum Analyzer, offering detailed insights. By understanding what is WiFi analysis, you can leverage these tools to ensure you're getting the best out of your network.

Best WiFi analyzer apps for your Mac FAQs

What is WiFi analyzer?

A WiFi analyzer is a software that can detect the surrounding wireless networks and gather detailed information about them. It should be able to provide you with such data as which channels networks use, their signal strength, encryption methods, etc.

Why a WiFi analyzer app is so helpful?

With a WiFi analyzer app you'll easily get the information about surrounding networks, analyze them and select the best WiFi channel for your router. Use a high-quality WiFi analyzer in order to create accurate wireless signal strength heatmaps for visual and comprehensive depiction of your coverage.

Why it is good to know which channel a wireless network operates on?

If your WiFi network has a lot of neighboring networks, then most probably some channels overlap, which is a common cause for a slower connection. A WiFi analyzer can help you find the least crowded channels, which should consequently help you achieve a better wireless performance.

What are the best WiFi analyzer apps?

Here is a quick glance at the best 8 WiFi analyzer apps:

  • NetSpot — the WiFi analyzer app for macOS with the most visual and comprehensive heatmaps, offering a free version and a reasonably priced paid version.
  • WiFi Scanner — this Mac OS wifi analyzer detects access points and clients in ad-hoc mode when the SSID is broadcasted. It's integrated with Wireshark for deeper network analysis.
  • inSSIDer — the basic version of this WiFi analyzer allows Mac users to collect all essential information about nearby WiFi networks and requires a MetaGeek account.

How do I run WiFi diagnostics on my Mac?

Here’s what you need to do to run WiFi diagnostics on your Mac:

  1. Press and hold the Option key.
  2. Click the Wi-Fi status icon in the menu bar.
  3. Choose Open Wireless Diagnostics.
  4. Select Continue in the popup window.

Just keep in mind that the built-in Wireless Diagnostics tool is pretty barebones, so consider installing a third-party WiFi analyzer Mac, such as NetSpot.

How do I know which WiFi channel is the best for Mac?

To discover the best WiFi channel for your Mac, you need to use a WiFi analyzer tool to scan all networks broadcasting in your area and determine which channels are used the least. To achieve the best performance possible, use only non-overlapping channels (1, 6, and 11).

Does Apple have a Wi-Fi Analyzer?

Yes, Apple does have a built-in WiFi scanner tool within macOS that you can access through the Wireless Diagnostics application. However, it's very limited and lacks the extensive features and in-depth analysis provided by dedicated WiFi analysis apps. For a more comprehensive understanding of your network, third-party applications like NetSpot are recommended.

How do I see all Wi-Fi networks on my Mac?

While you can see a list of available WiFi networks by clicking the WiFi icon in the menu bar or by using the Wireless Diagnostics application, this doesn't provide any detailed information about the networks, and it also doesn't list hidden networks. For a more detailed and comprehensive view and analysis of all the WiFi networks in your vicinity, it's best to download a third-party WiFi analyzer app, such as NetSpot.

Why no free Wi-Fi Analyzer for iOS?

Free WiFi analyzer apps for iOS are not readily available due to Apple's stringent security policies. Such apps were removed from the App Store in March 2010 because they used private frameworks, which are libraries that Apple's Developer Agreement explicitly forbids third-party developers from using.
