Common scenarios and fixes
Streaming
- If buffering or disconnects happen during streaming, switch to a server closer to your location or use WireGuard instead of OpenVPN.
- Enable kill switch to prevent leaks if the tunnel drops.
Gaming - Lower latency by choosing nearby servers and using UDP-based protocols; test both UDP and TCP.
- Consider split tunneling if only some apps need VPN protection, reducing overall tunnel load.
Work and education networks
- Some corporate networks block VPN protocols. Try a different protocol or a different server region.
- If you’re on a school network, using a mobile data hotspot might offer a more reliable tunnel.
Performance and privacy trade-offs
- UDP generally offers better speed; TCP is steadier on bad networks.
- WireGuard is faster and lighter but may have more complex firewall implications on some networks.
- DNS leaks undermine privacy; always verify DNS settings after changes.
