How Wi-Fi Direct differs from a regular wifi network
A regular wifi network requires a router or access point that every device connects through. Wi-Fi Direct skips that entirely β two devices negotiate a direct link with each other, so there is no router involved and no internet connection required. Speeds are comparable to a normal wifi connection, which is far faster than Bluetooth, and the effective range is similar to standard wifi as well.
When Wi-Fi Direct beats other transfer methods
Uploading to the cloud first requires an internet connection and is slower for large files since the data has to travel up and back down. Bluetooth works without a network too, but transfers noticeably slower. A USB cable works reliably but requires a physical cable and a compatible port on both devices. Wi-Fi Direct is usually the best option specifically for large local files, like videos or photo batches, when neither device has internet access.
Frequently Asked Questions
Does Wi-Fi Direct use my internet data or wifi network?
No β it creates a direct connection between the two devices and does not route through your router or use mobile data.
Why can't my two devices find each other over Wi-Fi Direct?
Check that both devices have Wi-Fi Direct or Nearby Sharing enabled and discoverable at the same time, that they are within a reasonably close range, and that airplane mode is not disabling wifi on either device.
