If you have a firewall or antivirus software installed that is not configured properly, then speed checker may not work correctly. Try to disable the firewall / antivirus when you are running the speed checker. After the test has been completed do not forget to turn it back on so you stay protected.
Any applications running on your PC can affect the speed, so you should disable temporarily:
Our speed checker downloads a file from the server and measures how long your connection takes to download it. The size of the file will be different according to your line speed.
We have tried to build the speed checker as accurate as possible but there are several factors that can affect the test. The speed checker measures the speed at the time of the test so if your network is running slow at that time then speed checker will report a slow speed. This does not necessarily mean that your internet connection is slow at the other times.
