Why Does TeamViewer Lag so Much?

By David Nield

The performance of TeamViewer depends to a large extent on a fast Internet connection at both ends of the link. But that's not the only factor. If you're experiencing lag and pauses when using TeamViewer, you can apply a number of software optimizations to get the most out of your available download and upload speeds and reduce the likelihood of future problems.

TeamViewer Settings

TeamViewer includes a number of settings for reducing the bandwidth required to stream video and audio across the Web. From the Options entry on the Extras menu, click "Meeting" and then select "Optimize speed" from the Quality drop-down menu. This setting turns down the video quality to improve the speed of the stream. Alternatively select "Custom settings" from the drop-down menu to manually set the related options yourself. Check the box marked "Remove own wallpaper" to further optimize TeamViewer and reduce the strain on your Internet connection.

Windows Settings

Ensure you have downloaded and installed the latest updates for the operating system using the Windows Update section of Control Panel. Close down any background applications or processes that are not required when using TeamViewer, particularly those that may be making use of your Internet connection, such as download managers or webcam-related programs. Right-click on the task bar and choose "Task Manager" to see running programs and utilities and disable them as required.

Internet Settings

Installing the latest drivers for your network devices, such as a Wi-Fi adapter or network card, and installing the latest firmware for your router can improve performance and fix persistent bugs. The relevant manufacturer's website should offer driver and firmware downloads together with installation instructions. To maximize the bandwidth available to TeamViewer, disconnect other computers and devices using the same router while the remote connection is active.

Other Optimizations

Ensure you're running the latest version of TeamViewer, which includes the most recent bug fixes and compatibility updates. If problems persist, uninstall and reinstall TeamViewer, which should be enough to eradicate any corruption within the program or its settings. Run a thorough security scan using your installed anti-virus and anti-spyware to check for any malware programs that may be utilizing your Internet connection or interfering with TeamViewer. Remember to troubleshoot and optimize both ends of the link, as problems at either end could cause lag when using the software.
