My Internet speed is slow after connected to VPN. What should I do?

A VPN is dependant on the speed of your connection to the Internet. Whatever the speed of the connection is, the VPN cannot be faster. In fact you should expect a small loss in speed generally because of all the added security, protocols and encryption carried out on end-to-end basis. This is done for the security of your data. This loss should be small, usually 10-20% when compared with your connection without a VPN.

If you are using VPN on mobile device, then older Android devices and early generation iOS devices may cause speed issues.Your only solution is to switch to a device with a more capable processor.

If you have a persistent speed issue consider the following troubleshooting steps:

  1. Change servers: Selecting a server that is geographically close to you will normally result in increased performance (due to lower latency). In addition changing to a server in another location may bypass any congestion issues depending on how close the congestion is to your location.
  2. Change VPN protocol: Different Internet Service Providers support different protocols. If you are experiencing slow speed, switch between the protocols i.e. L2TP, SoftEther (Windows) and OpenVPN. Switching between the protocols also resolves the disconnection issue.
  3. Turn off Firewall: Some Routers and 3rd party firewalls also cause speed and disconnection issues. Disable the Router / 3rdparty / Windows Firewall and check the connection stability and speed.
  4. Restart your Modem/Router: Over time your modem or router may slow down due to memory leaks etc. Restarting your modem/router may increase the speed of your connection and thus the VPN.

These suggestions should be helpful in resolving your speed issues.
