Breaking Vodafone Router
Original post is here eklausmeier.goip.de/blog/2022/06-16-breaking-vodafone-router.
In Aggressive Vodafone Router I already mocked about the software quality of the Vodafone router TG3442DE: software in this router was stone old, configuration was user unfriendly. In continuation of this: this router broke on 03-Jun-2022. No reboot or power off and power on method helped to make this device function again.
Luckily, the Unitymedia (now Vodafone) support on phone immediately sent me a replacement router. I wrote about the Unitymedia support here: Positive Erfahrungen mit Unitymedia.
The new router now offers "bridge mode", i.e., you can use it as a modem only. This clearly is an improvement.
DOCSIS signal strength is now as follows.
