WiFi has made our lives a lot more comfortable and more manageable. You don’t have to use an Ethernet cable to connect your devices to the internet, and WiFi allows for better portability and range. However, we still don’t give it any thought until something goes wrong and it becomes slow or stops working entirely.
Now, you can surely go and turn off your router and turn it back on again, but it rarely has been the perfect solution, and if you want to have the best network and browsing experience, then you need information and knowledge on what the problem actually is. This is where the following WiFi analyzers will come in and help you make the best of your WiFi network. So, let’s dive straight into it and get you the best tool to help you throughout your network issues.
What is a WiFi analyzer?
A WiFi analyzer is an app or a tool that helps you diagnose your WiFi connection and check if there really is an issue affecting your Mac or your router. While the “turn it off and on” solution often works for many devices, it’s not always the best possible solution to your problems. However, with a good WiFi analyzer, you can help your Mac stay online with the most vital possible signals and fast speeds. Here are some common problems that can be fixed by using a WiFi analyzer tool:
Slow performance – There are a lot of reasons for a slow WiFi connection and why some websites may load slowly. However, finding the exact cause might be difficult, and hence, WiFi analyzer tools come in handy to check and analyze all the problems related to your WiFi.
Dropped connections – Are you facing connectivity issues, or is your router not delivering on the promised range of the wireless connection. Well, a WiFi analyzer can help you out and check to see if you have the correct band enabled and how can you better position your router for the best possible connection range.
Public WiFi – Finally, the last thing that a good WiFi analyzer tool can help you with is searching for safe and secure public WiFi connections. Public WiFi can have problems and snoopers that can steal your data, and hence scanning for a WiFi service and checking to see if it’s safe to use is the ideal solution for using any Public WiFi network.
Let’s start with built-in Wireless Diagnostics
Apple clubs in a built-in diagnostics tool for all your network-related problems, and the Wireless Diagnostics tool deals with all WiFi related issues that you might have with your Mac. Here’s how you can get started scanning through your Mac WiFi problems:

How do I find the best WiFi channel on my Mac?
If you want to find the best WiFi channels for your macOS laptop or desktop, you will need to use a WiFi analyzer tool to help scan through all the available networks broadcasting around your area. This will help determine which channels are used the least, and then to achieve the best performance possible, use the non-overlapping channels around you, which generally are Channels – 1, 6 and 11.
How do I find out what network band My Mac is on?
You can find the network band of your WiFi network by holding down the “Option” key and clicking on the WiFi icon on your Mac’s navbar. This will show you a detailed report and analysis of your network and also tell you if your connection is on the 2.4 or 5GHz frequency band.
Is 2.4 or 5 GHz better?
There is no fitting conclusion to this question, but the 5GHz band is much faster than the 2.4GHz band due to two crucial factors. These are the bandwidth of the connection and the traffic around you. Hence, 5GHz is preferred if you want faster data transfer rates, and the 2.4GHz band is chosen when you need a better range and connectivity for a wireless network.
What is the best free WiFi analyzer?
There are a lot of WiFi analyzers in the market that promise to deliver a great seamless experience but put simply, and they can be expensive or not work as well as advertised.

What is dBm in WiFi?
dBm or decibels in WiFi is the value for the signals produced by your WiFi router or the access point. It is measured from the values 0 to -100, where higher values closer to zero (-30 to -50) are excellent for connectivity, and transfer rates and values closer to -100 (-80 to -100) implies a bad connection, and you should fix the issue as soon as possible for a seamless experience.
How many dBm is a good WiFi signal?
The ideal amount of WiFi signal strength that you want should be between -55 dBm and -70 dBm. This depends on how close or far away you are from your WiFi access. In Short, if you can get around -30 dBm = Excellent. It is the max achievable signal strength, and you would need to keep your device at most a few feet from the router.
While managing your WiFi connection can get a little challenging and stressful, the overall benefits you get with a stable and fast connection is just something that you shouldn’t miss out on. We have covered all the apps that can help you analyze and improve your WiFi network and hope that we might have helped solve your issue.
