Configuring FRITZ!Box for internet access via an Android smartphone (USB tethering)
Not only can the FRITZ!Box establish internet connections using a mobile broadband dongle, it can also use the existing mobile internet connection of an Android smartphone (USB tethering).
This way all devices in the FRITZ!Box home network can use the Android smartphone's internet connection to access the internet should your conventional internet connection ever be down and you do not have a mobile broadband dongle.
Requirements / Restrictions
- Android 4.1 or later is installed on the smartphone.
- The Android smartphone must support the USB tethering function.
Note:Not all smartphones support USB tethering. Refer to the manufacturer of the smartphone for information on USB tethering, for example consult the manual.
- Depending on the mobile network operator, internet telephony and all other functions for which a public IP address is required (for example incoming VPN connections) are either available or available only to a limited extent.
Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.
