What is Teams WiFi Dropping?
Teams WiFi dropping refers to a common issue where a Windows 10 device loses internet connectivity specifically during Microsoft Teams calls. This often happens because Teams consumes high bandwidth and maintains persistent UDP connections, which can trigger driver instability.
The problem typically manifests as a “No Internet” icon in the taskbar or a “Reconnecting” banner within the Teams app. In many cases, the WiFi stays connected for other apps but fails only when Teams is active.
Step-by-Step Solutions
1. Disable WiFi Adapter Power Saving
Windows 10 often shuts down the WiFi card to save power during high-load tasks like video conferencing.
To fix this, right-click the **Start** button and select **Device Manager**. Expand **Network adapters**, right-click your WiFi card, and select **Properties**.
Go to the **Power Management** tab and uncheck “Allow the computer to turn off this device to save power.” Click OK and restart your computer.
2. Reset the Network Stack
Corrupted DNS or IP configurations can cause Teams to lose its handshake with the router. You can refresh these settings using the Command Prompt.
Open the Start menu, type **cmd**, right-click it, and select **Run as Administrator**. Run the following commands:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns3. Update Your Network Drivers
Outdated drivers are a primary cause of WiFi instability on Windows 10. Visit the website of your laptop manufacturer (like Dell, HP, or Lenovo) or the WiFi chip maker (Intel/Realtek).
Download the latest “Wireless LAN” driver specifically for your model. Install the driver, reboot, and test a Teams call to see if the connection holds.
4. Clear the Microsoft Teams Cache
Cache files can become corrupted, leading to network authentication errors that look like WiFi drops.
Close Teams completely. Press **Win + R**, type `%appdata%\Microsoft\Teams`, and press Enter. Delete all files and folders inside this directory. Restart Teams and sign back in.
5. Disable GPU Hardware Acceleration
Teams uses your graphics card to process video. On some Windows 10 configurations, this causes a conflict with the WiFi hardware.
In Teams, click the three dots (…) next to your profile picture and go to **Settings**. Under the **General** tab, check the box for “Disable GPU hardware acceleration.” Restart the application.
