Internet extremely slow – dropped from 350+ Mbps to 38 Mbps since 3 weeks

fahimmahmood — Mon, 18 Aug 2025 20:37:55 GMT

For the past 3 weeks I have been experiencing major issues with my internet speed. I am a Vodafone Kabel Deutschland customer with the following contract:

Customer Number: 732xxxxxx
Contract Number: 773xxxxxx
Product: Red Internet & Phone 1000 Cable

Up until recently, I was consistently getting around 350+ Mbps download. Since about 3 weeks ago, however, my speed has dropped dramatically to just ~38-60 Mbps download

The problem persists regardless of:

Time of day (tested mornings, afternoons, evenings)
Connection type (LAN or Wi-Fi, same issue)
Device (PC, laptop, smartphone)
Router/modem restarts (done multiple times)

Upload speed is also worse. Streaming stutters, online meetings drop, and working from home has become nearly impossible.

I kindly request:

A thorough check of my line and, if necessary, a technical repair/dispatch. A new connection was installed as i recently moved my connection to new address.
Information whether there is a known outage in the Kaiserslautern area

If the issue persists and not resolved i will have no choice but to cancel it. Thank you in advance for your quick assistance.
