Does it feel like your connection speed isn't nearly as fast as it should be while using Mullvad? Try these methods to improve your speed.
Note: Almost all Internet providers that sell to consumers will not guarantee speeds, or if they do their bottom range is often half of what their sold speed is. For instance, Telia in Sweden says their speeds are 500-1000Mbit/s for their 1000Mbit/s connection. Bahnhof, another Swedish provider, does not have a guaranteed speed for connections over 100Mbit, but instead relies on best effort.
Using the Mullvad app
Install the latest version of Mullvad
Always use the latest version of the Mullvad VPN app. We are constantly making improvements, some of which can improve your speed.
Select the country closest to your location
If you do not select a country, the Mullvad app will default to Sweden. Click on "Switch location" in the app and choose a server that is close to your actual location. This can make your connection several times faster or slower, depending on country selected.
Switch to another city within the same country
You can select a city in the Mullvad app after you click on "Switch location" by using the down-arrow on the right side of the country.
Use a server from a different hosting provider
Mullvad servers are hosted by various providers in different data centers and your Internet provider might have better peering and speed to another provider. You can find the providers on our Servers page.
Try WireGuard protocol
WireGuard is the default protocol for Linux and MacOS, and you can select it manually in our app for Windows. Open the Settings, then click on Advanced. Under Tunnel protocol, click on WireGuard. Also make sure that the WireGuard key is valid by scrolling down to WireGuard settings > WireGuard key, and click on "Verify key" before you connect.
Change WireGuard port
Your Internet provider may limit the speed on certain ports. To change it, open the Mullvad app settings, then click on Advanced. Scroll down to WireGuard settings and set the port to Automatic, 51820 or 53 and see which works best for you.
If you use WireGuard standalone then you can change the port number in the WireGuard configuration file on the Endpoint line to almost any port number.
Change the WireGuard MTU
Some mobile networks require that you lower the WireGuard MTU to prevent connection stalling. Open the Mullvad app settings, then click on Advanced. Scroll down to WireGuard settings and set the MTU in the bottom to for example 1280.
Try OpenVPN protocol
OpenVPN is the default protocol for Windows, and you can select it manually in our apps for Linux and MacOS. Open the Settings, then click on Advanced. Under Tunnel protocol, click on OpenVPN.
Try TCP with OpenVPN
Several Internet providers throttles UDP connections. If that is the case, changing to TCP can show a significant increase in performance. Open the Settings, then click on Advanced. Under Tunnel protocol, click on OpenVPN. Then scroll down and go to "OpenVPN Settings". After that click on TCP and then 443.
Turn off multihop
Using multihop can improve your anonymity, however it also slows down the speed as the connection is routed from one Mullvad server to another, often in different locations. Open the Mullvad app settings, then click on Advanced. Scroll down to WireGuard settings and make sure that "Enable multihop" is not enabled. If you use OpenVPN protocol then go to the OpenVPN settings and set Bridge mode to Automatic.
Try another Internet connection or computer/device
To help you rule out problems with your Internet connection or router you can connect to a mobile Internet connection via a Wi-Fi hotspot and see if you get better speeds. You can also try it on different computers or devices.
Use an Ethernet network cable instead of Wi-Fi
A Wi-Fi connection can work fine, but it might be slower due to a weak signal or interference from other wireless networks, or appliances. Use an ethernet network cable instead to make sure that you get reliable speeds free from disturbance.
Try to use (or not use) our SOCKS5 proxy
Doing so might increase or decrease download speed depending on the circumstances. Follow our SOCKS5 proxy guide to get set up.
Temporarily disable your third party anti-virus and firewall
Try this to see if this improves your speed. Remember to turn it back on again after testing.
High speed Internet connections (1 Gbps)
If you have a very fast Internet connection then you can try to use Linux instead of Windows. The Linux kernel WireGuard implementation is faster than the Windows implementations. You can for example try to put Ubuntu on a USB stick and run it live to test it.
Using OpenVPN standalone
Use our configuration files
Connect to another server
Find the line "remote se.mullvad.net 1300" in the OpenVPN configuration file and change "se.mullvad.net" to one of the servers on our server list.
Update OpenVPN standalone
Make sure to update OpenVPN to version to 2.5.0 or later. If you are using Windows then add
windows-driver wintun on a new line in your OpenVPN configuration file.
Downgrade TAP driver (Windows 7 OpenVPN users)
If your speeds are resulting in kilobytes per second instead of megabytes, try downgrading your TAP driver to version 9.9.2_3.
Running an OpenVPN client on your router will likely perform much more slowly. This is because most routers have a slow CPU and will top out at roughly 5–20 megabits per second. In contrast, a modern PC can handle 100 megabits per second or more.
Temporarily disable your router's anti-virus/firewall
Test to see if this improves your speed. Remember to turn the firewall back on again after testing.
Also check if you have turned on "UDP Flood Defense". If you can't disable it then try to add the IP address of the Mullvad server to its whitelist.
Reboot your router
Some routers perform quite poorly after they have been running a while.
If you cannot solve your problem you can contact firstname.lastname@example.org. Feel free to provide us with a trace route to our VPN server by doing the following. Then please send us the result as text, not a screenshot.
First disconnect from Mullvad and then run the following command (replace the server name with the one you are using):
In a Command Prompt:
In a Terminal:
mtr -wz se1-wireguard.mullvad.net
