To share an internet connection, first identify whether the source is a computer’s network connection or a phone’s cellular data. Then choose a sharing method both devices support: Wi-Fi is the usual hotspot option, while Bluetooth and USB tethering work on supported combinations. The steps differ by platform, and cellular sharing may use plan data or depend on carrier terms.
Choose the source and sharing method
A Windows PC or Mac can share an existing network connection. An iPhone Personal Hotspot shares the iPhone’s cellular connection, not Wi-Fi it has joined. Most Android phones share mobile data. Before setup, check which methods the source and receiving device both support.
- Wi-Fi: Creates a hotspot that the receiving device joins from its network settings.
- Bluetooth: An alternative on supported device combinations.
- USB: A wired option where both devices support tethering and the cable fits their ports. A cable is not needed for Wi-Fi or Bluetooth.
There is no established, comparable speed ranking across these platforms. Apple notes that turning on Maximize Compatibility for an iPhone hotspot may reduce performance for connected devices.

Share a Mac’s connection with Internet Sharing
- Open Apple menu > System Settings > General > Sharing.

For Wi-Fi security, Apple recommends WPA3 Personal if every connected computer supports it. If some support only WPA2, Apple recommends WPA2/WPA3 Personal. Be cautious about configurations that share on the same port as the local network: Apple warns that some setups can disrupt network settings. If enabling sharing causes unexpected network problems, turn it off and check the source and output configuration, especially on a managed or shared network.

Turn on Personal Hotspot on iPhone
- Open Settings > Personal Hotspot.
- Turn on Allow Others to Join, if that option appears. Follow any setup prompt if Personal Hotspot is not configured.
- Review the Wi-Fi password on that screen. The hotspot’s network name is the iPhone’s device name.
- On the other device, open Wi-Fi settings, select the iPhone’s name, and enter the password. A Mac or Windows computer can also connect over Bluetooth or a compatible USB cable.
For USB tethering to Windows, Apple says Apple Devices or iTunes must be installed. iPhone Personal Hotspot shares cellular internet only; it cannot rebroadcast a Wi-Fi network the iPhone is using. Availability, fees, and the number of devices allowed can depend on the carrier and iPhone model. If Cellular Data is on but Personal Hotspot is not offered, ask the carrier whether the feature must be added to the plan.
