Why does my VPN keep disconnecting?
Common causes include unstable network, VPN server overload, firewall restrictions, or conflicts with antivirus software. Check your internet connection, switch servers, enable the kill switch, and review firewall settings.
Can VPNs leak my DNS?
Yes, if DNS requests bypass the VPN tunnel. Enable DNS leak protection in your VPN settings and consider using a trusted DNS resolver. Run a DNS leak test to confirm.
Should I use split tunneling?
Split tunneling can improve performance by routing only essential traffic through the VPN. However, it can reduce protection for non-tunneled traffic. Use it when you know what traffic needs protection.
How can I fix slow VPN speeds?
Choose a server closer to you, switch to a faster protocol like WireGuard, and ensure your device isn’t running bandwidth-heavy apps in the background. Check for ISP throttling and consider testing at different times of day.
Is it better to use TCP or UDP for VPN?
UDP is usually faster and preferable for most traffic, but TCP can be more reliable on networks that block UDP traffic. If you’re having trouble, test both. Troubleshooting Cisco AnyConnect VPN Connection Issues Your Step by Step Guide Optimized for Quick Fixes and Deep Dives
What’s a kill switch and do I need it?
A kill switch blocks all traffic if the VPN drops, preventing your real IP from being exposed. It’s highly recommended for privacy and security.
Can VPNs work on public Wi‑Fi?
Yes, but public networks can be unstable or block VPNs. Use a strong protocol, enable the kill switch, and avoid transmitting sensitive data if the VPN is unstable.
How do I troubleshoot a VPN that won’t connect on macOS/Windows/Linux?
Check for conflicting firewall rules, ensure the VPN client is up to date, verify credentials and server address, try a different protocol, and review logs for specific error codes.
What should I do if the VPN server is down?
Switch to a backup server in the same region or a nearby country. If all servers are down, contact support for status updates and ETA on restoration.
