Network trouble? Start here.
When two devices can’t find each other, the network is usually to blame, not the app. These pages tell you what to check, in order, with the real settings on iPhone, Mac and Windows.
-
Your devices can’t see each other
Six checks, most common first: same Wi-Fi, app open, Local Network permission, Windows firewall, VPN, a Wi-Fi that isolates devices.
-
Hotel, office or guest Wi-Fi
You have internet, but your devices can’t see each other: the network isolates them. How to tell, and what still works.
-
Transfer without internet, using your hotspot
No Wi-Fi, or a Wi-Fi that blocks: your phone makes the network, and files go straight from one device to the other.
-
Slow transfer: how to make it faster
The speed depends on the Wi-Fi between your two devices, not on the internet. Five checks, then the fastest setup.
