Why does TeamViewer freeze?


When using TeamViewer to connect to my home computer from school, it establishes the connection, then functions for a short period of time before freezing as soon as I make any changes to the remote PC. After that, TeamViewer won’t connect again. Why does TeamViewer freeze? And I wonder how to fix this problem, thanks.”

- Question from TeamViewer Forum


By default, TeamViewer is configured to use UDP to communicate with the host and client devices. This can create some latency over the network. Since UDP does not have any built-in error correction, then packets may arrive out of sequence or with a delay, ultimately causing the screen to freeze. Besides, an unstable network connection, a large system cache may also result in a freeze.
