If you're using a wireless connection, check your network signal strength. If the signal is weak, move closer to your internet router or access point for a stronger signal. Where possible remove obstacles between your device and the router. If that's not possible, use an ethernet cable to connect directly to the router.
Wireless network

We do not recommend using a wireless connection for WebRTC. Always use a wired connection for the best possible experience.
If you're using mobile broadband, switch to traditional broadband, such as fiber, if possible.
Mobile broadband connection

We do not recommend using a mobile broadband connection such as a 4G router for WebRTC. Always use traditional broadband, for example, fiber, for the best possible experience.
Restart your modem and router. Unplug both devices, wait for 30 seconds, and then plug them back in. Restarting these devices may fix temporary network issues.
Reduce the number of devices connected to your network. Disconnect devices that aren't in use to maximize available bandwidth. Ask other users on your network to avoid streaming videos or playing online games while you're on a call as this can negatively impact your connection.
Reach out to your systems administrator for assistance. They may be able to help you optimize your network for better call quality.
Contact your Internet Service Provider (ISP) for assistance. They can help diagnose any technical issues with your connection and optimize your network for WebRTC, ensuring you have the best possible experience.
Consider upgrading your PC. If your computer is old or slow, it may not be able to handle the demands of modern internet usage including WebRTC.
