Follow-up: Failure of the 2.4 GHz WLAN on the FRITZ!Box 7590 after approx. 5 years – repair options

Posted on 2024-07-21 by guenni

FRITZ!Box: Quelle AVM[German]Today I'd like to add a follow-up article on the failure of the 2.4 GHz WLAN on the FRITZ!Box 7590. A reader pointed out to me that this happens after about five years. According to research, a component (voltage converter) seems to burn out. AVM replaces the FRITZ!Box during the 5-year warranty period. Anyone who has fallen out of this warranty can dispose of the FRITZ!Box 7590 or have it repaired. In this context, I have compiled some more information to answer questions such as "Which boxes are affected?", "What are the risks?" and also to provide some information on repair.

Posted on 2024-07-19 by guenni

Stop - Pixabay[German]Over the last few hours, half the world's IT has probably been disrupted (at least it feels that way). It seems to me that there were two isolated incidents.
