Hi @henry1992,
We moved this topic from its original thread to avoid confusion.
spacedesk should work regardless of your network band, were there any errors you encountered when you tried to connect with spacedesk?
Could you please try the suggestions underneath “Troubleshooting -> Network Connection” chapter in the instruction manual https://manual.spacedesk.net/NetworkConnection.html
In case the above suggestions don’t work, could you please check if your iPad supports USB Tethering?
if yes, you can try connecting via iOS USB tethering.
Please check the ‘Connecting a New Display Monitor Over the USB Cable’ -> ‘USB Tethering (iOS and Android)’ chapter in the user manual –
