What is the bandwidth when sharing my screen in GoTo Room?
Sharing your screen during a GoTo Room session is not based on range or Wi-Fi.
The devices simply need to be on the same network so any wired or Wi-Fi connection that is in the same local area network (same subnet with no firewall) will be able to use the special "gotoroom.me" link and share.
Note: The connection from the internet (Network address translation) or through a firewall is not supported.
