Just because your ISP advertises certain WiFi speeds doesn’t mean that you’re actually getting what you’re paying for. Network congestions occur when multiple clients use a single shared Internet connection at the same time, which often happens in apartment buildings and with less reputable ISPs.
Virtually all WiFi speed test apps test the following components: latency, upload speed, and download speed. From the point of view of regular Internet user, download speed is the most important measurement as it dictates how fast websites load and how long it takes for websites to load, but latency and upload speed are also critical for having an enjoyable web browsing experience.
In computer networking, latency is the time it takes data packets travel from their point of origin to their destination. Let’s say you want to download a file from a remote server. You already have the download link, so you simply paste it into your web browser and press Enter.
Depending on your Internet connection, it may take anywhere from several milliseconds to several seconds for the download to begin because it takes a certain time for the server to fulfill the download request. The time it takes for the reply to arrive is latency, and WiFi speed test apps typically test it multiple times before determining the final result.
In the simplest terms, upload speed measures how fast you can send data to others. By others, we mean your friends and family on instant messaging applications, remote servers hosting various websites and services, and also your peers on file-sharing networks.
When WiFi speed test apps measure upload speed, they establish multiple connections to various remote locations and send precisely calculated chunks of data. The apps then determine how much time it took before all data were received and use this information to provide you with your real upload speed.
As you can probably guess, download speed measures how fast you can download data from others. WiFi speed test apps measure it by downloading chunks of data from remote locations and calculating exactly how long it takes for each chunk to download.
Signal strength is one of the most significant factors that influence the speed of your WiFi connection. A weak signal will result in slower data transmission speed. It may also be responsible for intermittently dropped connections. In order to reap the benefits afforded by a wireless network, maintaining signal strength throughout the coverage area is essential.
Distance is a key element in obtaining a strong signal and acceptable WiFi speed. The farther away from a WiFi router you are, the weaker the signal received by a connected device. Wireless networks that serve extended coverage areas usually employ signal extenders of some variety to provide connectivity to all of its users.
Sometimes your signal may be extremely weak, even when standing relatively close to your router. This can happen for a variety of reasons. You may be experiencing interference from nearby appliances such as a microwave oven or cordless phone that emits electromagnetic waves in the same frequency as your router.
The signal may also be impacted by walls or other impenetrable objects between you and your router. Where you place your router can have a tremendous impact on WiFI speed. A WiFi analysis tool such as NetSpot can help you find the ideal location for your router and enable you to increase your WiFi speed. You can use the application to test your WiFi signal strength from anywhere in your coverage area to identify the optimal placement of your router.
There are many online tools available with which you can test your WiFi speed. Just Google ‘WiFi speed test’ and you will find a free utility that lets you check WiFi speed. These tests can be very helpful in identifying issues with your network’s speed. But they need to be used correctly in order to deliver useful information.
A single test is not sufficient to show you the true speed your network will deliver. You need to test the WiFi speed from a number of locations within your coverage area and conduct the test repeatedly at different times of the day. The speeds reported by the tool may vary widely depending on when and where the test was run. Averaging the speeds will give you the best sense of the speed of your WiFi connection.
WiFi speed can also be affected by the channel or frequency the network is using to broadcast its signal. This is another area where a WiFi analyzer tool like NetSpot can be instrumental in allowing you to identify and address network issues. You can use the program to survey the area and see any signals that may be impacting you from competing WiFi networks.
The results of a survey will show you which channels are in use by other nearby networks. Using a busy channel will negatively affect your WiFi speed. The information provided by the survey can let you make an informed choice regarding which channel your network should use. A simple channel change can dramatically increase the performance of your WiFi network.
Similarly, the frequency that neighboring networks are using might slow down your WiFi speed. If all of the nearby networks are using the 2.4 GHz frequency, you might consider moving to the 5 GHz band to see if it improves your speed. One important factor to keep in mind is that the 2.4 GHz band is better at penetrating solid objects and may actually provide more speed in some settings that the alternative of the 5 5GHz frequency.
People often ask, “I want to test my Internet speed, but which WiFi speed test app should I choose?” The answer is simple: choose the app that best meets your needs.
As you’ll see, some WiFi speed test apps are extremely simple and designed to do just one thing, while others are more complex. If you’re a home user, you probably don’t want to spend long hours learning how to use a professional application that offers 100x as many features as you actually need. Instead, you should pick something that’s easy to use and comes with an intuitive graphical user interface.
Simplicity has its merits when you only need to check what your current WiFi speed is, but extra features come in handy when you decide to do something about it. Always select a wireless speed test app that supports the latest WiFi standards and the most commonly used WiFi frequency ranges. What may be even more important than features, though, is accuracy.
The last thing you want to do is accuse your ISP of not living up to its promises only to find out that the WiFi speed test app you’ve been using is inaccurate. There are many wireless speed test apps out there, but only a handful are mature, polished products that are ready for daily use. We recommend you to choose a wireless speed test app from a professional developer that knows how to develop world-class software and always stands behind its customers.
We’ve selected the top 4 best WiFi speed test apps that you can use to instantly check WiFi speed and picked our favorite.
Open NetSpot, start a new site survey and once in the Active Scanning screen - choose the wireless network you are going to test. Important to remember: you can run an active scan on a network you can access. It can either be an open network or a network you know the password for.

There are many online sites that offer to check your WiFi speed. They will check the upload and download speed as well as the ping rate of your wireless network. Testing your Internet connection with one of these tools will give you some numbers to work with, but can you trust the results?
Yes, Internet speed tests are typically accurate, but they are far from perfect. When a doctor measures a patient’s blood pressure, he or she knows there are a number of factors that may influence the measurement and compromise its accuracy. Similarly, there are many factors that may negatively influence the accuracy of Internet speed tests, and you need to be mindful of them in order to obtain accurate results. Among them are:
With all of the variables that can affect a WiFi speed test, the results may not be an objective indicator of the speed of your wireless network. In some ways, the best way to look at the results of a WiFi speed test is in relation to previous and future tests made on the same network. If you have made changes to your network meant to improve performance, you should see the average speed increase, but individual tests may still not be as fast as you would like.
When the goal of your testing is to see if your WiFi implementation can withstand the demands of gaming or heavy streaming, repeated tests at various times will give you a sense of the capacity of your wireless network. Numerous tests reveal the range of your WiFi speed and can alert you to issues that may need to be addressed to optimize your network and its coverage.
