Upstream issues causing disconnects again!

Upstream issues causing disconnects again!

Back at the start of the epidemic I was seeing frequent disconnects due to upstream issues indicated by my modem.  Typically I would disconnect and then see the upstream light on my modem flash green.

 

After a month or so of calling, texting and forum back and forth got a tech out here thanks to @ComcastAmir  whom I hope can possibly help again.  The tech found water in the line and up at the drop where critters had chewed into it, replaced the drop and everything worked great.. for a month and a half.

 

About 2-3 weeks ago I have started to have the same issue increasing in frequency.  I have pretty much had to go back to working from home hotspotted to my phone and the kids and wife are unable to enjoy some of the tech around the house, also concerning is the security system is linked to the internet.

 

I have tried other modems as well, currently have my CM500 connected which does the flashing green upstream when disconnecting as well as an old surfboard 6121 which sometimes shows a blue upstream a green upstream or no upstream indicator.  Both exhibit the same disconnect issues.

 

I have been getting the run around between the online assistant and the call center. 

 

June 26 I got a hold of someone on the assistant generating a ticket #051-214-679 and told me I would recieve a call from a technical support specialist in 24 hours.... didnt happen.

 

June 29th it took over an hour to get a real person on the phone who said that the previous ticket was closed, but would schedule me a call with a tech support specialist again even gave me a time 2-3pm on July 1st.  This would ofcourse be under a new ticket number 912-872-399.... again no call.

 

I am connected to the internet direct to the chord coming into the house so should not be any spitter issues.

 

So now I am here getting booted a few times from the internet so I can get the data for you guys to look at let me know.  Thank you!

Re: Upstream issues causing disconnects again!

Hey man just someone else on here updating my forum post. Noticed yours decided to read it. I'd like to mention that you forgot to include your actual upstream bonded channel levels. I did notice a lot of errors reguarding the upstream so those levels are imporant to know in such a situation. that could be your issue if the levels are out of spec.

Also when posting if you copy and paste and click the " Incert code " its a lot easier to post.

here is a example of what mine look like

Upstream Bonded Channels
Channel 	Lock Status 	US Channel Type 	Channel ID 	Symbol Rate 	Frequency 	Power
1	Locked	ATDMA	4	5120 Ksym/sec	17300000 Hz	47.0 dBmV
2	Locked	ATDMA	3	5120 Ksym/sec	23700000 Hz	44.5 dBmV
3	Locked	ATDMA	2	5120 Ksym/sec	30100000 Hz	44.5 dBmV
4	Locked	ATDMA	1	5120 Ksym/sec	36500000 Hz	42.0 dBmV

Now thats not too high tbh but I would be happy if they was a tad bit lower heh. I've been having packet loss issues. So I have ordered a new modem hoping this would resolve the issue. Hope you get some actual support soon because I know how frustrating this can be. Believe me I've been posting on here for about a month and have also reached out to tech support as well several times now. I've not gotten really any help at all so don't feel bad.  But if you can post your upsetream levels so we know whats going on on your end. 🙂

Re: Upstream issues causing disconnects again!

Sorry was called away on business for a few days.  Came home to internet still acting up.  Here is what I am getting after a reset for upstream.

Upstream Bonded Channels
Channel Lock Status US Channel Type Channel ID Symbol Rate Frequency Power
1 Locked ATDMA 2 5120 Ksym/sec 29400000 Hz 42 dBmV
2 Locked ATDMA 1 5120 Ksym/sec 35800000 Hz 42 dBmV
3 Locked ATDMA 3 5120 Ksym/sec 23000000 Hz 42 dBmV
4 Locked ATDMA 4 5120 Ksym/sec 16600000 Hz 42.3 dBmV

 

Not sure really if they are good at all and like I said just reset.  Got away with having internet for 30 minutes straight with myself and the wife on our computers working, then booted with the usual flashing upstream icon on the modem.

Thanks for responding to my message

Re: Upstream issues causing disconnects again!

already had a few disconnects after I posted.  Here is the the values after yet another reset.
