Simulate a failure - test your Internet Backup

Your Internet Backup isn’t working properly?

If the Internet backup stick doesn't work, the Internet backup LED on the router will flash white.


Proceed as follows:

LED flashes white quickly

Check whether the Swisscom services you ordered have been activated (activation date). If they have, remove the Internet backup stick from the router. Reboot the router and re-insert the Internet backup stick.

LED flashes white slowly

The reception quality at the router position is very likely insufficient.


  1. Enter the URL in your Internet browser to access the web portal. Please note that you can only access the web portal when you are connected to your router in the network.
  2. Check the reception quality of your Internet backup stick at Internet > Internet Backup. You can also check reception quality via the network coverage map
  3. In the case of insufficient reception quality, change the position of your router or place the Internet backup stick elsewhere (near a window for instance) by attaching it to a USB extension cable.
  4. You can connect up to 3 USB extension cables to cover longer distances. All USB 2.0 or 3.0 extension cables will work. You can order USB extension cables from our customer service (0800 055 055).
