Is there a way I can check how fast my Internet connection
is?
Yes, but you have to understand that most bandwidth tests from web pages are deceptive in the result they give you. Instead of testing how fast your personal computer is connecting to the Internet, they are measuring how fast your connection is to a specific server on the Internet. So, instead of telling you how fast your computer is connecting to the Internet, per se, you are getting a result of how fast you connection is to a server on the Internet. There are a number of factors that can impact dramatically the result of that type of test. Like how many other devices are between you and that server.
So, now you are asking yourself, "how do I test the bandwidth of my Internet connection?" Try the link below.
