Check if your network router has an 'Airtime Fairness' setting
Some routers will have an option for this setting. If your router has this, we would suggest disabling the setting to see if this resolves the issue.
If you have a Mesh network, ensure that the Network Player has access to the router and Mesh access points
It would also be worth ensuring that your Network Player is connected to the main router (base station), rather than one of the other connected access points.
Ensure that your mobile device and the Network Player are connected to the same network
Ensure that you have allowed the StreamMagic app to have access to devices on your network
You can check this via your mobile devices' app settings.
Check whether any VPN or Anti Virus app downloaded on to your mobile device may be preventing the StreamMagic app from 'seeing' the Network Player
If you have a VPN or Anti Virus app on your device, we would recommend temporarily removing or disabling it, to see whether this resolves the issue.
Ensure that the supplied WiFi dongle is securely connected
Check whether other apps and sources (TIDAL, Spotify, AirPlay, Chromecast etc.) on your device are able to 'see' the Network Player
If they are, this would suggest that something on your device is preventing the StreamMagic app from 'seeing' the CXN Network Player.
Download the StreamMagic app on to another mobile device, to see if it's able to connect to the Network Player
Temporarily remove any network switches, extenders, boosters etc. that may be part of your network set up
Connect your Network Player directly to your router via an Ethernet cable
