The VPN is slow
Test the server's own connection first, then try a lower MTU
What you see
- Pages load slowly through the tunnel and quickly without it.
- Large downloads stall while small pages still load.
Why it happens
The usual causes are the server's own network, its distance from the device, or packets too large for a network along the way.
-
Test the server's bandwidth
Run a speed test on the server itself. A tunnel is never faster than the server's connection, and a server far from its users adds delay to every request.
-
Lower the MTU on the device
Add this line to the [Interface] section of the device's WireGuard configuration and reconnect.
MTU = 1380 -
Pick a closer or bigger server
If the server's own test is slow, move to a plan with more bandwidth or a region nearer your users.
