Dynamic range window violation

Peterockinit
5 months ago

I keep getting this on my brand new (2 weeks old) sb8200 modem:

Dynamic Range Window violation

RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW

I have had 6 technicians out here. I have replaced my modem, my router, all my wiring (coax from dmark to modem and Ethernet with new cat6), cox put in a new drop from street to my house, have had all sorts of different attenuators for diff power levels. 

I saw several people post the same problem as me but there was never a solution. Can someone please help.

    I'm having this same issue also, almost exactly. I posted about it in these forums and they said they'd need to do some research on my exact situation, and eventually got back to me saying "there's a known escalated issue for your area that we hope to resolve in the coming weeks" and no further information on it; they can't attach my name to the ticket, they can't discount my service because it's barely useable, they can't give me updates as they occur, and of course they have no timeline for resolution.

    At least I haven't had to replace hardware and lines and pay for several technicians to come out. This is f*****g ridiculous.
