I changed my internet speed from 250 to 500 and thinking it would be a normal switch, i found out that my Technicolor was no longer compatible, so i had 2 days of no internet and telephone but my Horizon Box was working perfectly as it was not connected to the Modem.
I was sent a new Horizon Box even though i had one already as it was not known that i had the 2 separate services 1 Technicolor (For Internet and telephone)& 1 Horizon Box (For T.V) as my Horizon Box is not next to the wall outlet.
So for the moment i have 2 × 10m cable (From wall outlet to Horizon Box) connected to have the connection to Horizon Box.
Sorry for blabbing but now my question is can i make the Connect Box to be in bridge Mode (http://community.upc-cablecom.ch/t5/Internet-with-modem/Connect-Box-Menu-options-missing/m-p/79530#M153)) without calling again the support.
Thank you for your help with this.
