Thunder and lightning? Protect your FRITZ!Box

Protect your devices from lightning damage

We all love summer - as soon as we get a bit of sunshine, we flock outside and head to the nearest beach, lake or park. But it's not all about ice cream and barbecues - the rising temperatures also increase the risk of heavy rain and thunderstorms. With lightning, the storm zone voltage can fluctuate by up to 100,000 volts, causing damage to your electronic devices at home.

FRITZ!Box with integrated voltage protection

FRITZ!Boxes are protected, as each model has its own built-in surge protection. However, this protective mechanism does not provide 100% security. To prevent damage during a thunderstorm, you should take the following steps:

  1. In the event of a storm, unplug your FRITZ!Box from both the DSL connection and the power supply.
  2. Don't forget to unplug any landline phones, if you have them.
  3. As a precaution you should also unplug any power strips you have. This is because simply flipping the switch to off doesn't safeguard you or your equipment during a thunderstorm.

Diverting calls to your smartphone

Once you've disconnected your FRITZ!Box, you won't be able to access the internet or make telephone calls. To make sure your friends and family can still contact you, you can set up call diversion in advance, via your FRITZ!Box. If you select the option "Automatically" from the drop-down list "Outgoing caller ID", your FRITZ!Box will attempt to set up call diversion in the telephone exchange of your telephony provider, meaning calls to your landline will be forwarded to your smartphone.

When the storm is over (and you can come out from under the bed!), reconnect your FRITZ!Box to the DSL line and then to the power supply. Your settings will be the same as before, and you can go back to scrolling through your Instagram feed and watching funny videos on YouTube.

Is your FRITZ!Box damaged?

Since power surges destroy a FRITZ!Box's microelectronic components, they cannot unfortunately be repaired. However, many homeowners insurance policies cover damage caused by fierce thunderstorms and lightning - including a FRITZ!Box that has stopped working.
