Internet users are increasingly concerned with preserving their security and anonymity on the network. Currently there is a tendency to create profiles based on our browsing history, cookies and more. They are then used to send us targeted advertising for the products we have seen, and sometimes that information is sold to third parties. Much of this data is obtained from our public IP and our browser cookies. In this regard, to protect our Internet connection and in order to gain privacy, VPNs are increasingly being used. In this article we are going to determine the causes of why the Internet is slow if I connect to the VPN.
Why is the Internet slower if I use VPN?
A VPN is a computer network technology that allows us a secure extension of the local area network over a public or uncontrolled network such as the Internet. We are going to do this by establishing a virtual point-to-point connection through the use of dedicated and encrypted connections, and we are going to have confidentiality, authenticity of the connections and data integrity.
When we connect to the VPN we could say that it is based on taking a little “detour”. We send our traffic to an intermediate server that will be the one who hides our public IP and is responsible for sending us the data. However, that has consequences because we lose some speed and it also increases the latency of the connection a bit. Also on occasion we may be interested in exporting or importing a VPN connection .
The problem comes when for some reason we lose a lot of speed. This means that even browsing the Internet can be a frustrating task. Then it also loses other important virtues such as viewing multimedia content and downloads. The next thing we are going to do is address the reasons why this happens. Generally they can be because of the server or us.
Causes related to the VPN server
One of the reasons why the VPN connection is slow may be because we are connected to a server that is too far away . At the moment we connect to the VPN, if we do not choose our own country where we are located or one that is close, our connection may go slow. Either because we connect manually or automatically, the problem may be that we do not choose a close one.
Even though that server is in my own country, that VPN server may be saturated . This occurs when many people connect to the same server and the bandwidth is shared between all of them. In the event that this happens to us, it would be best to change the server to one as close as possible. Another issue is the encryption that makes the packets we send and receive take up more. In this regard, the higher the encryption, the greater the bandwidth that we will occupy. That does not mean that we disable the encryption of the VPN because it will not bring us too many improvements but we will lose in security against cybercriminals.
Issues influencing the VPN
If I don’t connect to the VPN, the problem may be with us. One of the most common failures is that some kind of software is interfering with the connection . The programs that can have the most negative influence may be a bad configuration of a firewall or an antivirus, since the latter, for example, individually analyze each packet that enters and leaves the computer.
Also another very determining aspect is our connection speed . If we have a 100 Mbps connection we cannot expect to achieve speeds of 300 Mbps. In the best of cases we will lose a speed of between 10 and 15% with respect to the contracted speed, although normally it is something more. Also a curious thing is that there are VPNs to play online . As for how to check our VPN, we can do it by observing its speed with a speed test and we can easily know if it meets our expectations. Also to improve we could change the type and encryption protocol of the data or the server to which we connect.
If I connect to the VPN and see that it is still too slow for my needs, it will be time to think about changing VPN provider because it is not giving us a good result.
