There are many factors to take into consideration when looking at VPNs. These are the main points to consider when analysing a VPN. Let’s take a look at them in this detailed guide. You’ll also find out the best way to check the speed of your internet connection.

Is a VPN slowing down your internet speed?

Both yes and no. It depends on your specific circumstances. The Internet speed can drop significantly when you connect via a VPN. It can also happen that the Internet speed increases dramatically.

You can expect an increase in Internet speed when you connect to VPN. This is not likely to happen immediately. It will usually affect your browsing speed but you might not notice it.

What causes a VPN to slow down my internet speed

A VPN could cause slow internet speeds.

  1. Server location

    Why? The speed of VPN connections is often affected by the distance between you and the VPN server.

  2. Bandwidth restrictions on the server

    Speed may be affected if the VPN server you use has bandwidth restrictions. This can also happen if your bandwidth is exceeded or the server is full.
    The speed of a VPN is directly affected by the VPN server. The server’s quality will determine how fast it handles encryption and data transmission. Your speed will increase accordingly.

  3. Types of encryption

    This can result in a decrease in speed depending on how secure the VPN protocol is. This happens only occasionally. Sometimes, the VPN does not have any effect on Internet speed.
    The VPN speed is generally slower with OpenVPN. PPTP, on the other side, is the fastest protocol. PPTP, however, is the fastest protocol. This is due to the absence of reliable encryption.
    An excellent intermediate option is the IKEv2, SoftEther, or L2TP/IPSec protocol.

  4. Interventions against the Firewall

    Firewalls are not usually able to slow down VPN speeds. However, they can cause problems with VPN cross-configurations or decrease processor performance.
    While we are on the topic, remember that VPN speed can also be affected by your CPU power. A VPN can cause a significant slowdown in your Internet speed if you are using old hardware. This is because the processor is responsible for encrypting and decrypting data.

  5. Network settings

    Some reports claim that you can get faster VPN speeds by connecting to your router via a LAN cable instead of connecting to it through a WiFi access point. The result will vary from one person to another.

  6. VPN routing algorithms

    The speed of a VPN can be affected by how your VPN provider connects to multiple servers.
    Free VPNs tend to use poor algorithms. You should expect slower speeds.

  7. Speed of your original connection

    It’s almost certain that your VPN will fail if your initial connection speed drops. If that happens, you can get a faster speed from your ISP.

With a VPN, why is the internet slow and laggy?

Users who have used different VPN services complain about slow internet speeds, slow website loading times, and overall “lags” and “slowness.” The problem seems to be that you need to disconnect your VPN. Everything is fine. Yes, the resource (sites) blocked access will not be accessible. These services are not used for online anonymity, connection security, or IP spoofing. It is very difficult to secure your connection via VPNs, even free ones.

Virtually everyone who connects via VPN servers uses them for accessing blocked sites and running blocking software. This is a very important point. Many useful and interesting websites and services can only be accessed in a specific country. All these problems can be solved using VPN.

This article will explain what a VPN is, how it works and what it is used for. It is a type of intermediary server. It works as though you are physically connected to Germany if the server is located in Germany. If you attempt to open a website from another country, your requests will not be sent directly to the server hosting the website. Instead, they will go through the VPN server.

Is it possible to speed up a VPN?

It is if you follow these tips, you won’t have to worry about slow internet connections via VPN.

  • You can choose a VPN Service that has no bandwidth restrictions.
  • Always connect to the closest VPN server to you. If it’s within your country, even better.
  • Your VPN connection should not be interrupted by your antivirus or firewall. Disable the firewall if it isn’t.
  • If you need to speed up your VPN connection, consider using a VPN protocol that uses less secure encryption (like PPTP).
  • You can play with the VPN protocol settings. OpenVPN UDP is faster than OpenVPN TCP.
  • You can suspend or turn off any applications or devices that are using your router but not right now (like a smart tea kettle).
  • Use a wired connection whenever possible. Because there is less competition for bandwidth, this will likely increase your VPN speeds. Reboot your router or modem. Rebooting your router or modem can solve this problem.
  • If you have a VPN installed on your router, you can also use the VPN directly from the device. To determine if the VPN speed is being affected by other devices, you can reboot them all.


It may be a good choice if you have considered other options and still decide to use a free VPN. It won’t surprise anyone that it can also impact your speed in certain cases.

Many free VPNs restrict the number of servers that are available to non-paying customers. This can cause servers to be slow and put more strain. Paying customers can access other servers, but they cannot get full speed service where there isn’t a load.

It is generally true that you often get what you pay when it comes to internet speeds using a VPN.

Speed test for VPN

A VPN speed test is the best way to determine if a VPN is slowing your internet connection. A VPN speed test will compare your internet speed to that of your VPN. The speed of your Internet connection is often measured in megabits per sec (Mbps).

This is a quick and simple way to test your VPN speed:

  1. Your VPN should be deactivated.
  2. Use your favourite search engine to find an “internet speed test”.
  3. Take the internet speed test to determine your upload and download speeds.
  4. Activate VPN.
  5. Connect to the VPN server
  6. Continue with step 3 and compare your results.

Remember, however, that your Internet connection is not a machine and that what matters most to you (known as latency) is how you perceive the delay (known also as perceived latency). A small amount of latency will usually not be noticeable in many situations. You may notice a slight increase in latency when you wait for an important transaction (e.g. a credit card transaction)

While objective speed tests can be a helpful guide, it is not a substitute for using the VPN in real life and seeing what effect it has on the things you care about.

What can I do to make my VPN work faster?

Choose a different server

The speed of your VPN is affected by how far your traffic must travel to the servers of your VPN provider. Speed is also affected by how many people are using the servers at once. However, other factors being equal, distance does play a role.

To get faster internet, choose the nearest server. You can choose another server nearby if the server is experiencing heavy traffic during peak hours to increase your internet speed. A VPN service is highly recommended, as it offers fast connections from many servers across dozens of countries.

Choose a VPN provider that uses WireGuard

A set of instructions called the VPN protocol determines how data is transmitted from your device to your VPN server. Your connection’s speed, security, and stability are affected by the VPN protocol. Because it is more secure, faster, and more efficient than OpenVPN, many service providers switched to WireGuard. WireGuard has been shown to be significantly faster than OpenVPN in many studies.

What is the definition of good speed?

The activities you do on the internet will determine your optimal speed. A speed of 25-30Mbps is considered acceptable for most home users, but it’s not a universal solution.

Consider how many Internet-connected devices you have in your family. What number of users will be connected at once? Although email is not very bandwidth-intensive, games and other activities require more.

Which country has the fastest internet connection?

South Korea boasts the fastest Internet speed, 26.7 Mbps. This compares to the global average speed of just 5.5 Mbps. South Korea’s internet speeds allow you to download HD movies in seconds and not hours.

Sweden is second with 19.5 Mb, followed by Norway (18.8 Mb), Japan (17.5 Mb) and the Netherlands (17.0 Mb).

Denmark is the country with the slowest Internet speed, at 16.1 Mbps. However, Hong Kong, Latvia and Switzerland have speeds of 16.6 Mbps to 16.8 Mbps.


How to speed up your VPN

A VPN can cause slow internet speeds in most cases. Because your traffic is routed through the VPN server, it adds an extra step to the data transfer process. However, the best tools, techniques, and settings can help you achieve the fastest VPN speed.

  1. Your internet speed can be checked

    Your VPN may not be the problem if your internet connection is slow at first. Do a quick test to see if your internet speed is the same with or without your VPN. This will allow you to determine if the VPN is causing the slowdown, or if you need to upgrade your internet plan.

  2. Try out different protocol settings

    Premium VPNs like NordVPN offer additional security features and other features that can affect the speed of your VPN. If you have access to the NordVPN app, go to Advanced settings and switch to another internet protocol. You can choose UDP to get a faster connection but you should be ready for possible instability. TCP is a faster but more stable option if you prefer a slower connection.
    You can switch between them as many times as you want. Remember that speed and slowness are both relative terms. You won’t notice any differences until you test the limits of your connection. NordVPN offers NordLynx as a lightning-fast protocol. It combines strong encryption with high speed.

  3. Change the encryption level

    You can adjust the type of encryption depending on your platform, device and VPN. Before you start playing with the protocols, make sure to research their differences and understand any potential risks. For maximum security, use the OpenVPN or IKEv2/IPsec protocols in NordVPN applications.

  4. Reboot your router and modem.

    It’s as easy as it sounds. A simple reset can help if your modem or router is experiencing slowdowns due to memory leaks, or other issues. A VPN connection to your router will be slower than one from your device unless your router is very powerful. If your router speeds are too slow for a VPN connection, the VPN can be used on your phone or computer. You should never use them both simultaneously as they will slow down your connection.

  5. Modify the server’s location

    Your internet speed may be affected if you choose a server that is far from where you live. A closer server can increase your VPN speed. You can try it for yourself. NordVPN’s easy interface will allow you to travel around the globe with your VPN connection.

  6. Make use of a wired connection

    Wi-Fi can be great but can slow down your speed, especially when you connect multiple devices to the network. Wireless connections share a channel to transmit data to multiple computers and phones within your home. This can slow down your speed. To ensure a faster connection, switch to a wired connection if possible.

  7. Deactivate the firewall and any other local security software.

    Your VPN speed can be affected by firewalls and anti-virus software. They filter out data sent to them. You can check if these tools are slowing down your VPN speed by temporarily disabling them. You do this at your own risk. While we would prefer you to lose some speed, it is better to keep your data secure by leaving VPN, firewall, and antivirus active at all times.

  8. Reboot your devices

    Your smartphone or computer may be “tired.” Turn it on and off to give it a new start. This is an old trick that can help you get maximum VPN speed.

  9. Use a VPN that is free.

    Although free VPNs may seem appealing, there is always a cost. Free VPNs often make profits by selling your data or finding other ways to make money. They also have a higher likelihood of providing poor security, stability, and speed.

What should you do?

A paid VPN is recommended for those who need to access blocked websites often and require a stable and fast connection. It works well. You can set it up in any browser, computer, phone or router. You can buy the most popular ones. Don’t chase cheap deals.

You don’t have to pay for a VPN. Instead, choose one browser and install the free VPN add-on. Only use that browser to access blocked websites. You can use another browser to visit non-blocked websites, download files, and so on. I recommend friGate and Opera’s built-in VPNs. You can also leave comments if you have other suggestions.

No good, fast-free VPNs exist.

A VPN can slow down internet speeds but not as often.

It all depends on many factors, such as the distance between you and the VPN server, which VPN protocol you use, the power of your processor, how the VPN redirects traffic, etc. A VPN can slow down your Internet speed.

There are steps you can take that will increase your connection speed via VPN. You can choose a server as close as you can, use a wired connection and disable your firewall. Don’t forget to test your Internet connection speed with the VPN speed testing tools we mentioned above.

If you use the tips above and select the right VPN provider, slow internet won’t be a problem.
