To use Cambly you will generally need a good internet connection. There are a few tools which can help you determine if you have a good connection.
SpeedTest.net can give you a general idea of how good you connection is. If you're noticing problems please test you speed and let us know what your speed is when you contact us.
Another common problem can come from firewalls or antivirus software, please try disabling any antivirus or firewall before connecting to Cambly. Corporate networks, Universities, and other public wifi sources sometimes block ports Cambly needs to communicate with our servers.
One of our chat providers has a tool to test connectivity which also might help diagnose certain problems, you can access that here: OpenTok Doctor.
