VPN works with Protocols, and all the VPN providers offer a range of different protocols. If experiencing speed issues, it’s better to switch between protocols such as PPTP, L2TP and OpenVPN. These protocols doesn’t affect your internet speed to a great extent especially PPTP. PureVPN windows dialer is built-in with automatic Protocol selection. If automatic protocol is selected then software will automatically connect to working protocol. If PPTP and L2TP are blocked on your network then it will connect to SSTP which is high encrypted protocol and may decrease your speed. You are suggested to try OpenVPN UDP and TCP manually incase PPTP and L2TP are blocked on your network.
Some routers have by-default settings that disabled the PPTP, L2TP and IPSec pass through. You can check your setting under ‘Firewall’ or ‘Security tab’ and if it is disabled then enabled it. It is also possible that your Anti-virus firewall blocks PPTP and L2TP. You can allow the PPTP and L2TP protocols through your 3rd party Anti-Virus firewalls.
Most Canadian ISPs support L2TP and provide better speed than PPTP.
Routers and 3rd party anti-virus firewalls also hindered your way to fastest speed. Disable the router or 3rd Party and Windows Firewall and check connection speed.
3- Geographic distance to server
If you chose a VPN server too far from your location, in that case you will not get the maximum speed from that server. Simply it’s because the network information travels around the earth to reach the destination and then back to the server. Just to help our users, we have purpose selection tool that finds you the best available server as per your desired purpose and take care of your internet speed.
For Mac, iOS, Android and Router users check your speed with PureVPN speed test tool here: http://www.purevpn.com/speed-test
You can follow our guides to setup VPN manually by using these easy guides: http://www.purevpn.com/tutorials.php
For Windows users, you need to click on Purpose drop down menu in the dialer and select your desired purpose.
Speed is directly related to the Protocol you select. PPTP is less encrypted and offer higher speed whereas L2TP and SSTP are more secure and offer high level encryption up to 256-bit therefore they offer slow speed. Whenever user increases encryption level it decreases the speed. However, OpenVPN may give you high encryption with good speed.
5- Your Internet Connection matters more than anything for Speed:
You can test internet speed by following these simple steps:
- Switch off your VPN
- Go to www.speedtest.net
- Choose the same country as the VPN server in the map (let say you need a US server to access Netflix, then select US just to check your internet speed from your location to USA without VPN)
- Now check your Internet Speed
- Connect to VPN
- Now check your speed again but this time with VPN
