- Actionable fixes to stabilize your connection and prevent drops.
- How to choose a VPN that's optimized for real-time communication.
Why Does My VPN Keep Disconnecting on Teams?
Understanding the root cause is the first step to a permanent fix. A VPN connection drops during a video call for a few key reasons. VPNs encrypt your data and route it through a remote server, which adds extra steps to your internet journey. Microsoft Teams, especially when video is enabled, requires a constant, high-bandwidth, low-latency connection. When the VPN server becomes overloaded, your local network has issues, or the two software programs fight for control, the connection can falter. Common culprits include aggressive firewall settings, outdated network drivers, or using a VPN server that's too far away, introducing too much lag for a stable real-time call.
Quick Fixes for VPN and Teams Stability
Before diving into advanced settings, try these simple solutions first. They often resolve the issue immediately.
1. Switch Your VPN Server
The physical distance between you and the VPN server significantly impacts performance. If you're connected to a server on another continent, try switching to one geographically closer to you. Also, look for servers labeled for “gaming” or “streaming,” as these are often optimized for speed and stability, which also benefits Teams calls. A simple server switch can drastically reduce latency and prevent those annoying VPN connection drops.
2. Restart Your VPN and Router
It sounds too simple, but it works. Fully exit your VPN client software and close Microsoft Teams. Then, unplug your router and modem from the power source, wait 30 seconds, and plug them back in. This clears the network cache and resets your connection. Once your internet is back, reconnect to your VPN and then launch Teams.
3. Run Teams as an Administrator
Sometimes, Teams needs elevated permissions to function correctly alongside other network-intensive applications. Right-click the Teams icon and select “Run as administrator.” This can help it bypass certain network restrictions that might be causing conflicts with your VPN.
Advanced Network Configuration
If the quick fixes didn't work, it's time to adjust some deeper Windows and VPN settings.
Configure Your VPN's Kill Switch
A kill switch is a critical privacy feature that blocks all internet traffic if your VPN connection drops unexpectedly. However, some aggressive kill switches can be too sensitive and may misinterpret normal network fluctuations as a disconnect, cutting you off from Teams. Check your VPN's settings for the kill switch and see if you can adjust its sensitivity or temporarily disable it during calls to test if it's the culprit. Remember, disabling it reduces your security, so re-enable it afterward.
Adjust Windows Firewall and Antivirus Settings
Your firewall or antivirus software might be incorrectly identifying VPN-encrypted Teams traffic as a threat. You can create an allowance for Teams. Go to Windows Security > Firewall & network protection > Allow an app through firewall. Find “Microsoft Teams” in the list and ensure both Private and Public boxes are checked. You may need to do the same for your VPN client in its respective antivirus settings.
Update Network Drivers
Outdated network adapter drivers are a frequent source of instability. Press the Windows key + X and select “Device Manager.” Expand the “Network adapters” section, right-click your network device, and select “Update driver.” Choose “Search automatically for updated driver software.” A new driver can often resolve compatibility issues that lead to a VPN connection drops.
Choosing a VPN Optimized for Video Calls
Not all VPNs are created equal, especially for real-time applications like Microsoft Teams. If you're constantly battling instability, it might be your VPN service itself. The best VPNs for this purpose offer a combination of blistering speeds, a vast network of reliable servers, and features designed to maintain a steady connection.
Look for providers with:
- WireGuard Protocol: This modern protocol offers a great balance of speed and security, perfect for video calls.
- Obfuscated Servers: These servers disguise VPN traffic, helping you bypass network throttling from your ISP that can disrupt Teams.
- Dedicated IP Addresses: While not essential, a dedicated IP can sometimes prevent you from being flagged by corporate security systems.
Best VPN This Month
For unmatched stability on Microsoft Teams, we recommend ExpressVPN. Its Lightway protocol is specifically engineered for speed and reliable reconnection, making VPN connection drops a rare occurrence. It consistently tops our performance reviews for real-time applications.
When All Else Fails: Split Tunneling
If you've tried everything and your VPN still can't maintain a stable connection with Teams, split tunneling is your ultimate solution. This advanced feature allows you to choose which apps use the VPN tunnel and which connect directly to the internet. You can route only your sensitive traffic (like web browsing) through the VPN while letting Microsoft Teams use your regular, high-speed connection.
This eliminates the VPN as a variable for Teams entirely, guaranteeing call stability. The trade-off is that your Teams data is no longer encrypted by the VPN. To set this up, look for the “Split Tunneling” feature in your VPN's settings and add Microsoft Teams to the “bypass VPN” or “excluded apps” list. You can find more detailed guidance on using this and other advanced features in our privacy guides.
Secure and Stable Calls Are Within Reach
A VPN connection drops during a Teams call doesn't have to be a regular part of your workday. By methodically troubleshooting from simple restarts to advanced split tunneling, you can identify and resolve the conflict. The key is often a combination of using a high-quality VPN service, ensuring your local system is up to date, and properly configuring your software. Don't let connectivity issues compromise your productivity or your privacy.
