You run some Wi-Fi speed checks and get quite low results that don’t match our internet plan? Then you doubt the quality service of your ISP or your mobile carrier. Wait a minute! That might not be their problem as there are other factors also affecting your Wi-Fi speed. Check out this article of “Speed check: Top reasons for slow Wi-Fi connection” to know  more!


Slow and sluggish Wi-Fi is something so frustrating. It makes us not be able to well engage in online activities. Sluggish internet connection, of course, results in poor speed test results. With a certain number of Wi-Fi speed checks, you will know how strong your wireless connection really is. In case you see that your Wi-Fi speed is much lower than the wired speed, then the problems here might not be from your Internet Service Provider (ISP). Do you know that your Wi-Fi signal strength is affected by many different factors? Let’s check out the top reasons for slow Wi-Fi connection right below here to see if there’s any one of them causing your Wi-Fi signal to be weaker than it would be.


With a certain number of Wi-Fi speed checks, you will know how strong your wireless connection really is

Distance to the router

Wi-Fi signal originates from the router/modem and travels through the air to your devices. Therefore, the farther the distance, the weaker the Wi-Fi signal and the slower network speed. That’s why your Wi-Fi speed check results are never high if you are too far away from your router when testing the speed.

Building materials and physical obstacles

Materials like concrete and metal are one of the biggest reasons causing slow Wi-Fi. That is because the Wi-Fi signal is easily disrupted by brick, concrete, wood, drywall, metals, and other building materials. They can be considered ''blockers'' that block or interrupt your Wi-Fi signal as it is transmitted through the air and has to pass through these types of materials to get to your devices. In short, the more walls and physical obstacles the Wi-Fi signal has to travel through, the weaker it will become.

Router positioning: High vs Low

Placing your router on low positions such as on the ground or the bottom of the shelf or even behind other furniture is a direct way of hindering Wi-Fi connection. It’s so hard for your Wi-Fi signals to easily penetrate if it is placed at low positions. Instead of that, you should put the router as high up as possible that helps extend the broadcasting range of your wireless signal. You can run speed checks to see if the change of router height and position can help improve your Wi-Fi performance.


Router height and position really affects your wifi speeds

Wireless interference

Wireless signals are all around us. Electronic devices, Wi-Fi routers, cell towers, satellites, and more are the sources of wireless signals. Though the Wi-Fi signal is supposed to not have the same frequency as these other devices, the radio noise can still cause interference.

Besides, there are devices and appliances such as Bluetooth devices, microwaves, cordless phones, etc, running on the frequency range of 2.4 GHz, which is close to or at the same 2.4 GHz Wi-Fi band. So, there are times when the frequency of these devices can overlap with the frequency of Wi-Fi signals. And when that happens, the data being transmitted via a Wi-Fi connection are likely disrupted. Well, when you have many things running on the same frequency range, then your Wi-Fi speed check results tend to be much lower than the wired speed test results.

Old router – One of the common reasons causing the results of your speed check to be slow

Using an old router might be one of the reasons for lowering your Wi-Fi speed. The routers that age for more than 5 years might not be able to fully support high-speed internet. That’s why you should consider upgrading your router if you are sure that it’s the big cause of low Wi-Fi speed.

Have not rebooted the router for a long time

Most electronic devices and equipment were not made to run continuously and your router is not the exception. If it’s been so long since the last time you reboot your router, then this might be the reason causing your Wi-Fi speed to slow down. Try restarting your router and run a speed check again to see if your Wi-Fi speed test results are higher or not. Sometimes, a simple reboot is what you need to do to help it return to peak performance.


Sometimes, your device is the reason causing poor Wi-Fi connection

Your devices are not able to handle advanced Wi-Fi speeds

Many times, what causes your Wi-Fi speed to slow down might not be your router, but your own devices. Your PCs, smartphones, and tablets, each of them has different speed capabilities. Your Wi-Fi speed is just as fast as the speed of your devices. That means no matter how fast the router is, it can’t go faster than your devices’ speed, especially if the devices you use are older than 5 years old. 

In fact, though newer devices will typically have higher internet connection speed than the older ones, they still may not be able to reach the same speed as a wired connection. You can run speed checks to compare the differences in internet speed results between your old and new devices.

Speed check: Too many devices using the network at the same time

Many devices connected to your Wi-Fi network at a time is also the cause for a huge decrease in Wi-Fi speed, especially if they are joining in bandwidth-heavy activities like streaming Netflix or online gaming. Well, if you run speed checks at hours when your internal Wi-Fi traffic is overloaded, then you will find your speed test results are much slower than usual.

Running speed tests is always a good idea to know your current Wi-Fi speed. Together with common testing tools available on the market these days like Speedtest.net, Fast.com, or Testmy.net, …,  MySpeed is also a great speed check tool for you to try. Try it now to see how fast your speed is!


They are 8 common reasons causing your Wi-Fi speed to slow down. Of course, in addition to these reasons, there are many other causes for decreases in the speed of your Wi-Fi connection. What we mentioned above are just very common ones that a lot of us are likely experiencing in daily life. Finally, we hope that you find today’s article of “Speed check: Top reasons for slow Wi-Fi connection” and its information interesting and useful!
