Corporate or campus networks

• Ask for VPN allowance: Some networks block VPN ports; verify with the network admin.
• Use a different port or protocol: Some networks block common VPN ports; switching can help.
• Check for captive portals: Sign in on any login page before VPN can function.

Mobile data vs. Wi‑Fi

• Cellular networks: VPNs usually work reliably, but carrier-grade NAT or restrictions can affect performance.
• Wi‑Fi networks: Guest networks and public hotspots may block VPN ports; use cellular as a test.

Protocol and encryption considerations

• WireGuard vs OpenVPN: WireGuard is faster but may behave differently on certain networks. If one protocol fails, try the other.
• Port availability: Mullvad typically uses UDP ports, but some networks block standard ports. Try alternate ports recommended by Mullvad.
• DNS leakage: Ensure your DNS queries aren’t leaking outside the VPN tunnel. Enable DNS over VPN if available.

Service status and error codes

• Common Mullvad error indicators: Connection timeout, authentication failure, tunnel establishment failure.
• Check Mullvad status: Service outages can affect all users or specific regions.
• Logs review: Mullvad client logs can reveal where the handshake or tunnel establishment fails.
• Time and date sync: An incorrect system clock can cause certificate validation issues.

Performance considerations

• Server overload: If a chosen server is overloaded, disconnect and switch to a less crowded location.
• Bandwidth limits: Some networks impose throttling; test by running a speed test with and without VPN.
• Peering and routes: Some routes are slower due to interprovider peering; try a different region.

Security and privacy reminders

• Always verify the VPN app signature and source before reinstalling.
• Use multi-factor authentication if offered by Mullvad for account access.
• Regularly review connected devices and active sessions in your Mullvad account.
