FRITZ!Box 6810 LTE Service - Knowledge Base
Constant restarts: Several LEDs flash
The FRITZ!Box constantly restarts (reboots, resets). When this happens, all or several LEDs either flash briefly several times or continuously one after another. Since the FRITZ!Box keeps restarting, you cannot access its user interface. Either particular functions or all of the FRITZ!Box functions are not working properly.
Important:If the FRITZ!Box occasionally restarts, follow the instructions in this guide.
Simply proceed as described below. After each measure, check whether the issue persists.
1 Restarting the FRITZ!Box
- Unplug your FRITZ!Box by removing the power cable from the electrical outlet.
- Plug it in again after 5 seconds.
Note:The FRITZ!Box settings will not be deleted when it restarts. The restart will take about 2 minutes. During this time, you cannot access the FRITZ!Box user interface.
2 Using the correct power supply unit
One of the most frequent causes is the use of an unsuitable power supply unit for the FRITZ!Box. For example, you may be using the power supply unit from a different FRITZ!Box model:
- Use the power supply unit included with your FRITZ!Box to plug it in.
3 Resetting the FRITZ!Box
- Use the recovery tool to reset the FRITZ!Box.
