Which are the requirements regarding the internet connection for Arthur to work?

• The bandwidth requirements are quite low and lie between an audio and a video conference.
• The connection should be 3mbit download and 2mbit upload at a minimum per device. Furthermore, 5Ghz should be the preferred network.
• If the Wifi connection is not stable, switch to a mobile phone hotspot instead (See Can I also use a mobile hotspot to use Arthur?)
