Are you using the ConnectBox?


If so, log in (user: admin, password is on a sticker on the bottom of the modem/router) by going to


Make sure your UPC TV box is turned on and click "Connected Devices" in the router admin menu on the left.  Do you see a device called "UPC-TV-BOX"?  If you do, then the box is correctly connected to your network and some time tomorrow someone from UPC will see your post here and activate your TV package. 


If you don't see that device listed, then something's wrong with your connection.  It should be easy ... use the cables that were provided with the UPC TV box / ConnectBox and ... ConnectBox to wall socket with coax.  UPC TV box to wall socket with coax.  UPC TV box to TV with HDMI.  UPC TV box to ConnectBox with ethernet (aka lan) cable (or you can use wifi, but physical connection is better here).

Betreff: error code cs1011 -please help

@jk4536 , I switched your modem to IPv4 as a test. Please do the following:
- Restart your Conenct Box (Modem)
- Connect your UPC TV Box via LAN cable (without switches, powerlines or routers in between)
- When the Connect Box is online again, reset the UPC TV Box.


Reset UPC TV Box:

Press and hold PWR / CH- when switching on using the toggle switch until the Welcome Screen appears.
