2.5 Setting up a mobile fall-back WAN connection
Mobile fall-back
The MediaAccess Gateway allows you to use a mobile Internet connection (for example, 3G) as fall-back connection for
your Internet access. This means that the MediaAccess Gateway will automatically switch to the mobile Internet connection
when your normal Internet connection is down.
The MediaAccess Gateway will automatically switch back to the normal Internet connection as soon as it becomes available
again.
What do I need?
To set up mobile fall-back connection, you need:
A mobile USB adapter
A registered Security Identity Module (SIM) card.
Configure the mobile interface as WAN connection
Proceed as follows:
1 Configure your mobile connection.
For more information, see “2.5.1 Managing your mobile connection with the MediaAccess Gateway GUI” on page 26.
2 Insert your mobile USB adapter.
For more information, see “2.5.2 Inserting a mobile USB adapter” on page 27.
3 Now your mobile connection is up and ready to use.
Result
MediaAccess Gateway will automatically enable your mobile Internet connection when both of the following conditions are
met:
The main Internet connection has been unavailable for at least 60 seconds.
The MediaAccess Gateway received a request to access the Internet (for example, when browsing to an Internet
website).
The MediaAccess Gateway will automatically disable the mobile Internet connection in either of the following cases:
The main Internet connection is available again. In this case the MediaAccess Gateway switches back to the main Internet
connection.
No Internet traffic has been detected during the last 10 seconds. For example, you finished surfing the Internet.
Only use the mobile USB adapters provided by your service provider.
If you need to remove your mobile USB adapter, make sure the MediaAccess Gateway is powered off first.
