I need it for work tomorrow

If this is a breakdown of your line, it will not work until tomorrow.

Got a new cable and still doesn’t work

the error e1 is not only related to your cable between junction box and the router. It could be also a fault in the cable within the house, the street, or somewhere else.

Was it working before the 2 days?

Did you already call the Hotline? Why the did not help? Language Problems? It is also possible to wait here for the Team Members of @Telekom-hilft-Team . There are also some english speaking members if nesesarry.

It worked yesterday morning, but I noticed from around 5pm yesterday

No, it’s not working 

I don't think that we will get the problem solved here ... I notify the Team...

Hi @Fab098,

thank you for the call. And lucky as we are, there was even an appointment with a technician for tomorrow morning! Yay! 🥳

So please tell me how everything will have worked out.

Sincerely,

Johannes P. 

Fixed now. Thank you!
