Why does my download speed not match the speed test?

After internet speed tests work completely, you get a good result but your network connection seems still slow. In other words, Download speed not matching speed test. Why is my download speed slower than speed test? The below things may be the reasons. 

“Up to” speeds

Your ISP (internet service provider) can't control your overall online experience because your speed is only going to be as fast as the slowest segment between you and the site you’re trying to visit.

Think of your promised internet speeds by ISP, it is the same way you think of a speed limit sign. 

Although the freeway sign says you can go 75 mph, you’ve got no shot of going fats at that speed during rush hour because of the congestion on the freeway.

ISPs offer “up to” speed which represents the best-case scenario

ISPs offer “up to” speed which represents the best-case scenario

ISPs offer you the internet connection with perfect “up to” speed as an incentive trick for customers to choose them as well as that number represents the best-case scenario with one device connecting the internet.  

Therefore, if test results aren’t the same as their actual speed, you are able to be fell into trap of the internet provider.

ISP hosted tests

Many of the most popular internet speed tests encourage ISPs to host a testing server on their network to help increase the chances that their users will get the fastest test results. 

Often get high speed when use ISP hosted tests

This is a good thing, however, the problem with this approach is that unless you only use websites hosted by the company that connects you to the internet or their peering networks, it doesn't represent the real world. 

Therefore, to get the real result as well as not have the contrary as mentioned above, you should be suspicious of any speed-testing website or app your ISP (internet service provider) suggests you use.

Independent testing site

Test results don’t reflect the true situation that can be you don’t still use an independent and credible testing site. 

One test site that has no affiliation to any of the ISPs, independent and safe for users is MySpeed or you can access https://gospeedcheck.com/.

Using the credible speed check online provides you with more accurate results as well as useful information to help you raise the internet performance quality. 

Understanding the variables

There are so many variables that can impact your actual online experience. Even they can't relate to the internet plan that your ISP is providing you. 

Those variables can be:

  •  The time of day: peak hour & peak-off hour

  • The website you’re trying to connect to foreign & local websites

  • Whether you’re using wireless network Wi-Fi or have a wired connection: Wifi interference like Microwave, Bluetooth, cable materials, furniture, ...

  • The age of your modem: life cycle of router/ modem is 3-4 year

  • An old cable, bitten, leaked cable

  • How many other devices on your own network are currently using the same network connection

  • …..

Each of the above factors can impact download speed test results somewhat. 

For example, when you are playing an online game, someone in your house tries to download files. That time, the result of a speed check online should be a bad, slow connection. If not, there is something wrong. 

Further, the other thing to remember is that when you run any of these tools, you’re taking a snapshot of that moment in time, which can be extremely misleading. 

Therefore, it is necessary that you really need to run a series of tests at different times of the day over several days to truly determine your average speeds. 

That time, the test result is more objective and may delete the situation when the test result is good but the internet is so slow and lag.

Other things 

Moreover, the contraction between the test and reality result can be due to some errors while running the test. It is often advised that to perform speed tests correctly, you need to take notice of:

  • Turn off VPN (a virtual private network)

  • Disable firewall, malware

  • Turn off an unnecessary background process

  • Stop downloading large files, playing online games, or streaming movies,...

VPN or firewalls have no influence on downloads rate but they can create some errors in the speed check internet. The reason is that VPN, firewall, malware are the 3rd parties of your network connection. 

VPN can cause download speed not to the match speed test

VPN can cause downloading results unequaled speed test 

If you check the internet speeds while enabling them, the tool might misunderstand and measure the speed of the 3rd party. As a result, the downloading result isn't equal to the test result is certain.

Similarly, online activities such as downloading large files, streaming Netflix movies, and background processes take up a large amount of downloading data. When doing these activities at the same time, the results can't be correct completely.
