Frequent Disconnects - No Ranging Response received - T3 time-out - Low Downstream
No splitters in the circuit, modem is conneceted directly to grouding block. No TV's connected.
Arris SB6121.
Disconnects were intermittent before. I chatted with tech support via webchat and they did something-now its worse.
I tried calling 1-800-COMCAST and they keep insisting on sending a reset signal and don't let me talk to an agent. Really frustrated here.
Logs and signal cuts below.
@ComcastMikeC please help.

FWIW, ComcastMikeC hasn't posted here since 2012.. Call 1800comcast and book a tech to come out and investigate / correct. Good luck !

It's hard to get a tech out right now unless your service is completely down due to COVID 19, sorry.

Had no idea, thanks.
That's exactly the problem I can't even book someone if I wanted to. In an endless "We are going to send a reboot signal, call back in 10" Then I call back. Then "We are going to send a reboot signal, call back in 10".
Rediculous.

Still having this issue. Currently I have a cable flying out of my window because "it works"
Need a tech to come investigate Comcast's side because I am only getting -11 dBm downstream signal strength at the grounding block. Same value with three different cables from block to modem.
Today its -13 dBm

@EG I am getting frequent disconnects and its disrupting my ability to work from home as required by my employeer. I am unable to make an appointment with a tech via phone or web. I tried the web chat and the representative didn't offer a technician and said I basically can't have anyone come out until after June 30. I could lose my job if I don't get this resolved.
Can you please escalate my issue to someone who can investigate the issue on comcast's end or at least dispatch a technician.

Hi @drktmplr12,
Sorry for the experience you're having with your internet. I understand how frustrating this can be, especially if it's affecting your ability to work from home during this time. I'd be happy to investigate and see if I am able to get a tech out sooner, but I also can't make any promises due to measures put in place because of COVID-19. Please send me a private message with your first and last name (and the name of the account holder), and the house number associated with your service address. To send me a private message, click on "ComcastChe" and then click send a message.

not sure why but my modem's clock is 1 hour behind my computer's clock. only pointing out that the time outs coincide with severe packet loss followed by outright disconnection.

FWIW, that's normal. Cable modems do not do daylight savings time.
