Re: Intermittent disconnects - CODA-4582U

I've been having internet connectivity issues for the last 35 days.

 

At random points in the day, connectivity is slow and websites hang. There are intermittent disconnects to all my devices (wireless and wired). We've had 6 Normal Technicians and 2 Senior technicians come by to address the issue.

 

The outside line to the pole has already been replaced. We even tried connecting the modem directly to the cable coming from the pole and there was no improvement. We've had our CODA-4582U and Eero Hub replaced, new cables and all.

I have gone through several phone technicians, with the same process(restart modem, the plug is in the wall instead of a power bar, factory reset etc) many times.

 

I'm not sure what else there is to do, but switch service providers. I am very happy with the service Rogers provides, but during a time like this, I cannot successfully work from home.

 

I have seen other posts with similar issues, but haven't seen any solutions.

 

Has anyone else encountered said issue?

Re: Intermittent disconnects - CODA-4582U

Hello,

 

I have the CODA-4582U modem and have been having intermittent disconnections on my internet over the past month. Rogers sent multiple technicians only and have not been able to resolve the issue.  I have been monitoring logs and so far they have shown critical and warning messages.

I am having the exact same problem as you. I couldn't even type this reply because the internet got disconnected.

Re: Intermittent disconnects - CODA-4582U

Hi @Datalink,

 

Update: tech replaced something old at neighbour cable connection (at the main cable) & replaced connector for me (on the wall of building); some update, I don't see yet huge change (such as suggested 37-40 dB for upstreams):

Re: Intermittent disconnects - CODA-4582U

Rogers replaced two connectors: one was on their main cable going to neighbour, and another one on my house external wall. Rogers mentioned water was leaking inside connector. Thank you!

 

No disconnects in about 36 hours, and single disconnect 10 hours ago with a lot of logs.

 

And this looks strange:

Re: Intermittent disconnects - CODA-4582U

I am having the same issue..I have called multiple times to customer sevice and have had technicians come and replace equipment..still the same. Working from home is frustrating. I will have to consider switching to other providers.

Re: Intermittent disconnects - CODA-4582U

Hey @paheerone

 

Sorry to hear you're experiencing disconnects as well :(. We'd be happy to assist in identifying what's going on. To begin there's just a few things to check off query wise if that's alright. Would you mind confirming for us:

 

  • Are the disconnects occurring with a wired or a wireless connection
  • Does the light pattern on the modem change when the disconnect occurs?
  • Do all devices lose connection at the same time?
  • When did this issue first start occurring?
  • Does it occur during a particular time period?
  • When was your most recent technician visit?
  • Can you log into your modem and provide the WAN Status page information? We can review your signal levels to see if there's a visible issue there.
  • Are you using your own router/switch in the home?

Thanks!

Re: Intermittent disconnects - CODA-4582U

Wired and wireless.

Most of the time the light pattern does not change, but sometimes the router loses connection and resets.

Yes, all the devices lose connection at the same time.

This has been happening since early this year, but its more noticeable now since I am working from home.

This problem happens all times of the day and night.

Technician last came on April 29th.

I am using the rogers modem, no other routers.

Re: Intermittent disconnects - CODA-4582U

After three visits of technicians, I have "visible" improvement: dark blue upstream indicator on modem. It was previously amber (last week, before technician changed two connectors on street).

 

Upstream channels were showing 53 dBmV past few days, and only two channels. Today, it is four channels, but while writing this post modem disconnected again, with all 4 channels around 42-45 dBmV, so I don't think it is same issue as before...
