FRITZ!Box 6840 LTE Service - Knowledge Base
The "Info" LED continuously glows red
When the "Info" LED continuously lights up red, the FRITZ!Box is signalizing that there have been functional restrictions over a longer period of time (for example the Internet or telephone connection may be interrupted), atypical usage behavior, or it signifies other urgent notifications. The exact cause is displayed as a message on the "Overview" page of the FRITZ!Box user interface (see fig.) and is displayed or is repeated regularly until the cause is eliminated.
