daily restart of modem

I am in the 600MBps band and used to clock around 700Mbps at all times. 

Once the recent work from home in MI started, the speed slows down to 6Mbps or even slower. I have to restart the modem to get back to decent speed. I have to do this multiple times a day.

Noting much has changed in terms of modem/router, #connected devices. Same number of devices as during the weekend when we all connect our laptops & phones.

 

Why is this happening & what is the remedy?

Re: daily restart of modem

What do the modem's signal stats look like ? Try getting them here http://192.168.100.1 or here http://10.0.0.1

Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

What is the exact make and model number of the modem ?

Is this a WiFi connection ?

Re: daily restart of modem

It is a LAN via ethernet.  It is connected to the back of a Netgear Orbi router.

Re: daily restart of modem

The signal stats were o/k at that snapshot in time. Are there any RF error / event log entries being shown ? If so, please post them too.

Re: daily restart of modem

Even though the signal stats looked o/k at that snapshot in time, the error log entries confirm that something is going on. Perhaps there is noise ingress into the line(s) somewhere.

 

There are other signal stat figures that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.


I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. They can check the CMTS (Cable Modem Termination System) for any real time degradation and / or error reports, see your node / cable plant and modem health, and see whether or not everything is in the green zone. They can also see a history plot for the modem and poll for those upstream receive signal stats.

You should get a reply here in your topic. Good luck !

Re: daily restart of modem

I've had the same issue and have a similar post. However, it still has not been resolved even after 2 modems and a new line put in. I am not sure what the issue is, but I haven't called back because I haven't had the time to spend with them. It takes literal hours to accomplish anything and still have nothing resolved.

Any idea why my modem would have a 1970 time stamp? Seems like a lot of folks with intermittent connection issues have the same T3 error with 01/01/1970 timestamp.

Re: daily restart of modem

channel 37.JPGToday, I'm seeing a lot of T6 issues related to hannel 37. @EG had mentioned somewhere that this "Other" channel is related to Gigabit speed tier. I am not on that plan.  So far today, the speed has been stable.

I have also been going back to check any recent software updates/upgrades. Recently, Malwarebytes did a big update and I wondered if that was conflicting with the modem/router firewalls and also possibly Norton Security.  It also added a Malwarebytes ad blocker for the chrome browser. I have disabled Malwarebytes for now. Let me see if things stablize.

That's what a modem defaults to using when for whatever reason, when it is having difficulties talking to the T.O.D. (Time Of Day) server.

Hello @ComcastChe  @EG  : After several hours of steady internet speeds, the problem returned with the same error (going to 01/01/1970).  This morning I reset the SB8200 and so far so good. I am awaiting the deep dive results from @ComcastChe

Hi @Shankarhokie!

 

Sorry for the delay. Yes, I do have an update for you. Based on what I see, I've been communicating with your local techs to get this escalated since I cannot schedule a normal tech visit. I've just received the ok today, so I will be replying to your private message shortly. I have a few more things I need to verify before I can get this up to them. Chat with you soon.

Re: daily restart of modem

April 24th update.

 

Tech showed up promptly at 10 am.  He maintained social distance and asked what issue I was having.  I explained my having to restart the modem daily.

 

Tech mentioned that this is a bandwidth issue with everyone being online at the same time. He said that Comcast designs the network nodes and infrastructure for 50%  average utilization and now it is more than 90% putting a strain on the bandwidth. 

He said that there were several techs working in our neighborhood checking the cables because of complaints.

He cautioned me NOT to restart the modem during the latter part of the day since the modem may not be able to connect back.

He checked everything outside and did not find an issue.  The signal strength, quality, channel powers were all within bounds.

He said that Comcast in investigating adding some more nodes in the area to reduce the number of homes  using a single node.

 

I guess I will have to wait for Michigan to fully open up and all of us to start going back to work before this problem stops.

Until then, I'm going to do a restart early in the morning and hope for the best!

I will keep updating my daily findings.

Re: daily restart of modem

Thanks for the update @Shankarhokie!

Although he wasn't able to do anything to completely resolve the issue, it's a good thing that he was able to isolate any issues at your home or with your equipment and confirm that your local techs are aware and investigating. Please keep us updated. If things get too bad for you reach out in our private message and I'll see what I can do.

Re: daily restart of modem

@ComcastChe @EG Please Help!

 

We are having the exact same issue and nobody is helping. After half a dozen chat sessions with support all they can do is tell us to reset the modem. Today, they flat out disconnected the chat when we asked for escalation. On the phone we were also promised someone was coming to check outside the house but never showed up.

 

Why keep paying for 900Mbps service when our average daily speeds are around 20 Mbps? Please have someone come check the service. We have top of the line equipement all with recomended settings and regular tests showing poor sertive across WiFi and Ethernet on multiple devices and times of day. Our device setup inside the house has not changed. This is almost unusable with so many reboots required. What is going on here?
