Why Mullvad VPN can feel slow
If you are trying to figure out how to fix Mullvad VPN slow connection issues, the first step is understanding what usually causes the slowdown.
VPN speed depends on server load, encryption overhead, routing distance, your local network, and device settings, so the problem is often fixable without changing providers.
Mullvad is designed for privacy, not speed claims, but it still performs well when configured correctly.
The challenge is identifying whether the bottleneck is the VPN tunnel, your ISP, the selected server, or something on your device.
Check whether the slowdown is really caused by the VPN
Before changing settings, test your baseline connection.
This helps you separate Mullvad issues from general internet problems.
- Disconnect from Mullvad and run a speed test on your regular connection.
- Reconnect to Mullvad and test again using the same device and location.
- Repeat the test on another device if possible.
- Compare latency, download speed, and upload speed rather than relying on one result.
If speeds are slow even without Mullvad, the issue may be with your ISP, Wi-Fi signal, router, or local congestion.
If the slowdown appears only when the VPN is active, move on to VPN-specific fixes.
Choose a server closer to your location
One of the simplest ways to fix a slow Mullvad connection is to switch to a nearby server.
The physical distance between you and the VPN server affects latency and throughput because your traffic has farther to travel.
For the best results, select a server in the same country or region when possible.
If you are using Mullvad for general browsing, streaming, or remote work, a nearby exit node is usually faster than a distant one.
Also avoid overused locations during peak hours.
A server in a major city may be technically close but still slow if many users are connected to it.
Try a few different servers in the same country to compare performance.
Switch between WireGuard and OpenVPN
Mullvad supports both WireGuard and OpenVPN, and the protocol you choose can have a major effect on speed.
In most cases, WireGuard is faster because it uses a lighter codebase and modern cryptography with lower overhead.
That said, OpenVPN can be useful in some networks where WireGuard performs poorly or is blocked.
If your Mullvad connection is slow on one protocol, test the other.
- WireGuard: Usually best for speed and lower latency.
- OpenVPN: Sometimes more compatible on restrictive networks.
After switching protocols, retest at the same time of day so the results are comparable.
Try a different port or transport method
Some networks handle VPN traffic more efficiently on specific ports or transports.
If your connection is unstable or slow, changing the transport can make a noticeable difference.
With OpenVPN, different ports may help bypass throttling or packet filtering.
With WireGuard, the default setup is often best, but network conditions can still affect throughput.
If you are using a work, school, hotel, or public Wi-Fi network, traffic shaping may be interfering with the VPN.
Mullvad also supports options that can help on restricted networks, including bridging or obfuscation in certain scenarios.
These features are not always necessary, but they can help when a network actively limits VPN traffic.
Disable split tunneling mistakes and unnecessary background traffic
Split tunneling can improve performance when configured correctly, but it can also create confusion if the wrong apps are routed through the VPN.
Check whether large downloads, cloud backups, game launchers, or sync tools are using the tunnel when they do not need to.
Background traffic can consume bandwidth and make a VPN feel slower than it is.
Pause or close the following while testing:
- Cloud sync services such as Dropbox, OneDrive, or Google Drive
- Operating system updates
- Streaming apps and auto-playing tabs
- Game updates and launcher downloads
- Backup software and photo syncing
Reducing competing traffic is especially important on slower home connections, older routers, or shared networks.
Improve local Wi-Fi and router performance
Many users blame the VPN when the real issue is weak Wi-Fi.
A fast VPN cannot outperform a poor local connection, so check your home network setup carefully.
For better results, try these fixes:
- Move closer to the router or use Ethernet instead of Wi-Fi.
- Restart the router and modem.
- Switch from 2.4 GHz Wi-Fi to 5 GHz if your device supports it.
- Update router firmware.
- Disconnect unused devices that may be consuming bandwidth.
If your router is old, it may not handle encryption-heavy VPN traffic efficiently.
Modern routers with stronger CPUs usually perform better with VPN connections, especially when many devices are active.
Update Mullvad, your OS, and network drivers
Outdated software can cause poor VPN performance.
Make sure you are running the latest version of the Mullvad app, your operating system, and, on desktops or laptops, your network adapter drivers.
Updates can improve protocol handling, fix bugs, and resolve compatibility issues that affect throughput.
This is particularly relevant on Windows, macOS, Linux, Android, and iOS, where background system changes can alter VPN behavior.
If the slowdown started after a recent update, check Mullvad’s release notes and your system logs for clues.
Sometimes a temporary regression is fixed quickly in a newer build.
Check for DNS issues and IPv6 conflicts
DNS problems usually do not lower raw bandwidth dramatically, but they can make browsing feel slow by delaying website lookups.
If sites take a long time to load after connecting to Mullvad, DNS may be part of the problem.
You can also test whether IPv6 is causing routing conflicts.
Some networks and devices handle IPv6 poorly alongside VPNs, which can lead to inconsistent performance or delays.
Useful checks include:
- Testing another DNS resolver if your setup allows it
- Clearing the device DNS cache
- Temporarily disabling IPv6 to compare results
- Opening a few different websites to see whether the slowdown is general or site-specific
If DNS is the issue, pages may begin loading faster immediately after the cache is cleared or the network stack is refreshed.
Look for ISP throttling or congestion
Some internet service providers slow down specific types of traffic or reduce speeds during busy hours.
Although a VPN can sometimes help with throttling, the reverse is also possible if the provider identifies and limits encrypted traffic patterns.
To investigate, test your Mullvad connection at different times of day.
If speeds are acceptable in the morning but slow at night, congestion is likely affecting your line or the VPN server you selected.
Try the following:
- Compare weekday and weekend performance
- Test multiple nearby Mullvad servers
- Measure both VPN and non-VPN speeds at the same times
- Check whether one streaming service or website is slower than everything else
Consistent patterns usually point to congestion, routing, or ISP shaping rather than a faulty app.
Use Mullvad features that support performance and privacy
Mullvad includes privacy-focused design choices that may affect how you troubleshoot speed.
Features such as automatic connection handling, relay selection, and the ability to change protocols give you flexibility when the network environment is not ideal.
When testing performance, keep your setup simple.
Connect to one server, use one protocol, and avoid extra privacy layers until you have identified the cause of the slowdown.
Once performance is stable, you can re-enable additional protections if needed.
If you use advanced features like custom DNS, obfuscation, or router-based VPN setups, confirm that each component is configured correctly.
A misconfigured router, firewall rule, or custom script can create artificial bottlenecks that look like Mullvad speed issues.
When to contact support or change your setup
If you have tested nearby servers, switched protocols, updated software, and ruled out local network problems, the issue may be more specific.
At that point, gather details before contacting support so troubleshooting is faster.
Include the following information:
- Your device and operating system
- The protocol you are using
- The server location
- The time of day the slowdown occurs
- Speed test results with and without the VPN
- Any recent changes to your router, ISP plan, or firewall settings
Clear diagnostics make it easier to determine whether the slowdown is caused by a server route, local network constraint, or device configuration.
In many cases, the fastest fix is simply choosing a better server, using WireGuard, or cleaning up the local network path.
