      I didn't even spot that, would that include the TV box?

      If not, seems someone at Virgin has been messing around with the profiles.

       

      I know the router has been replaced twice before so maybe they forgot to remove the bindings on the CMTS.

       

      I wonder what happens if you plug 3 modems in? Never heard of that being done before.

       

      Has anyone ever heard of more than 1 CPE?

        Yes the Tivo boxes count as CPEs

      On our wavelength

      Had a very similar thing this week. Just "magically" started one afternoon... and just as mysteriously went away again... ( 2025-07-18 )

      ( Yesterday evening - 2025-07-21 )

      it's been rock solid before. No explanation at all from VM.

    I'm looking at the US is this on the high side?  I believe these should be around the low 40's ?
