Frequently Asked Questions

Why does WireGuard fail to configure on Surfshark?
WireGuard requires specific kernel modules that may not be loaded or available on your system. This commonly happens on older operating systems, certain Linux distributions, or systems with restricted kernel access.
Is OpenVPN as secure as WireGuard on Surfshark?
Yes, OpenVPN is highly secure and widely trusted. While WireGuard is newer and potentially faster, OpenVPN provides excellent encryption and security for your VPN connection.
Will switching to OpenVPN affect my connection speed?
You may notice slightly slower speeds with OpenVPN compared to WireGuard, but the difference is usually minimal for most internet activities. The improved stability often outweighs any minor speed reduction.
Can I fix WireGuard without switching protocols?
Sometimes yes, by updating your OS, running Surfshark as administrator, or reinstalling the app. However, switching to OpenVPN is the most reliable immediate solution while you troubleshoot the WireGuard issue.
Does this error mean my VPN isn't working at all?
No, this error only affects the WireGuard protocol specifically. Surfshark will still protect your connection using OpenVPN or IKEv2 protocols once you switch in the settings.
