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 send 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.

When you first go to the administration website: It is quite annoying to be warned that ones browser seems to be old. This warning is just plain wrong.
