If you experience a slow connection, make sure all players are connected to the same Wifi as your AirConsole console device (computer, tablet or AndroidTV).
You don't have to be connected to the same WiFi to play together. Hybrid connections also work. Meaning that half of the party can be connected to mobile data and the rest on the local WiFi. However, we recommend you to all connect to the same Wifi.
We also recommend using the AirConsole App on your smartphone. Make sure it is always updated to the latest version. If you don’t use the AirConsole app, we recommend using Chrome on your smartphone.
If this does not help with your issue, please refresh your console, by refreshing the browser window or restarting the Android TV App.
In addition make sure, all your devices, browsers and apps are up to date.
