Storms ahead? How to safeguard your devices from lightning damage

We all love summer – but the rising temperatures also increase the risk of heavy rain and thunderstorms. Lightning strikes can cause the storm zone voltage to fluctuate by up to 100,000 volts. This poses a potential hazard to your electronic equipment at home. We've put together some tips and tricks to help you increase the safety of your FRITZ!Box and other devices.

Safer in three steps

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

  1. Unplug your FRITZ!Box from both the power supply and the DSL connection. You should also unplug FRITZ!DECT, FRITZ!Repeater and FRITZ!Powerline devices connected to the mains.
  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. Simply flipping the switch to off doesn't automatically safeguard you or your equipment during a thunderstorm.

Diverting calls to your smartphone

Once your FRITZ!Box is disconnected, 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. 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, for example.

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

Lighting and your FRITZ!Box – what to do?

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. This also applies to a FRITZ!Box that has stopped working.
