Why is my VPN slow? Common causes and fixes
The most common causes of slow VPN speeds and how to fix each one.
A VPN adds encryption and a different network route, so some performance change is normal. There is no reliable fixed percentage: the result depends on your base connection, Wi-Fi, device, distance, congestion, protocol availability, and the test destination.
1. Server distance
Longer routes usually add latency. Start with Auto and choose a nearby location, then compare another nearby location if the first route performs poorly.
2. Protocol choice
Protocol choice changes the balance between speed and compatibility. Leave Protocol on Auto first, then manually compare only options currently shown as available for your platform and location.
3. Server load
If the app shows load or latency information, use it as a comparison rather than a guarantee. A nearby alternative can perform better even when two locations look similar.
4. Your base internet speed
Run a speed test without the VPN first. If your base speed is 10 Mbps, the VPN can't exceed that. Contact your ISP if base speeds are lower than your plan.
5. Hardware limitations
Older or busy devices may struggle with encryption and high throughput. Keep Protocol on Auto, close heavy background apps, and repeat the same test before changing connection settings.
Use the built-in Speed test before and after connecting under similar conditions. There is no single expected percentage because Wi-Fi, distance, congestion, device performance, and the test destination all affect the result.
