I’m using the Connect Box, and my broadband connection has now been down for more than 4 hours.
- In the overview panel, the “Your Connect Box status” shows red arrows for Internet, with “DS scanning”.
- I ran the Network diagnostic tool, which indicates “Your broadband connection is down. Please check your coaxial cable.”
- I checked the coaxial cable and re-plugged it on both ends, it still doesn’t work.
- I reset the box to factory defaults, it still doesn’t work.
- On the other side, my Service Status page at https://www.upc.ch/en/myupc/service/service-status shows everything available.
There were also the following “network logs” in the box, I indeed remember the connection dropping sometime between 15:10 and 15:20 today, which correlates with the various errors at 15:17.

What else can I do? Can you send a technician to check that the broadband is indeed working at the coaxial plug on my wall, as reported by the Service Status?
