DHCP on the LAN side. Devices unable to obtain an IP.

Re: CODA-4582 - Open Issues for Investigation

I sent Dave a Private Message about this issue to see if he can look at this and talk to Hitron.

This is an easy fix in that some networks have some heartbeat process incorporated that sends some data packet to the device to keep the connection active if there are periods of inactivity. Perhaps Hitron could look into something like this.

Re: CODA-4582 - Open Issues for Investigation

Its a moot point for me now as I switched to Bridge mode with a EdgeRouter X. Just thought I would let Rogers know about the DHCP.

Re: CODA-4582 - Open Issues for Investigation

Is it too much to ask for a proper working firmware before pressuring me with email and text messages to swap modems?

Yes. I have seen the exact same thing. Numerous times. CODA-4582 firmware .24 2nd gen black dot. Modem in standard gateway mode. Happens with wired devices, as well as 2.4G tablet, laptop. Randomly, usually after a few hours of inactivity. Service usually resumes within about 10 seconds once device or webpage access is attempted a few times. No entries in DOCSIS Event log (and modem doesn't reboot – has been up for almost 4 days now with no speed degradation!!). Almost like modem having trouble finding the right IP match for the device; so... DHCP issue???

 

Also, perhaps related to this, saw the following in the event log today:

 

20 02/21/2017 11:44:30 68010300 error DHCP RENEW WARNING - Field invalid in response v4 option;CM-MAC=xx:xx:xx:xx:xx:xx;CMTS-MAC=xx:xx:xx:xx:xx:xx;CM-QOS=1.1;CM-VER=3.1;

 Question to everybody, is this a new thing that you have observed only on 2.0.10.24 or something that existed before and need to be adressed by Hitron?

 

It has never been reported before so I just want to ensure it is reported correctly.

For me just with .24 I had started to see this.

Reporting back in.

 

Swapped my modem last night for a newer, black dot version. I was stuck on 2.0.10.13 until this afternoon when @RogersDave kindly pushed 2.0.10.24 to the modem for me. 

 

So far after 5 minutes of being back up, looking good! All pings are under 30ms now. Channels do not appear to randomly be missing either.  I see channels 9-40 with none missing in between.

 

I'm assuming it will take a bit to stabilize and will do extended testing before deciding that there is further issues. I am only pulling about 400-500 Mbps download, 38 Mbps upload. Prior to getting .24 on my original CODA, and then this new one that Dave pushed .24 to, I was able to get 850 Mbps down and 45-49 Mbps Up without much issue (save for the speed degradation over time on .19).

 

I can also report that while doing a speedtest, pings can get crazy and go into the thousands and timeout. Not sure if the CODA is getting clobbered with bandwidth / packets or why it can't seem to ping well while under heavy load.

@notregistering can you run a modem restart/reboot now.  Pull the power, wait for 30 seconds and plug the power back in to force a restart.  After that, check to ensure that you have 32 DOCSIS 3.0 channels running and the DOCSIS 3.1 channel as well.  If you have any issues after the restart, consider running a factory reset.

Sweet, and good luck! Let us know how it goes!

 

Looks like you're not on DOCSIS3.1 yet.
