Re: CODA-4582 - Open Issues for Investigation

Can someone post and pin a TL;DR on the issues and fix from this thread, I don't have time to go through 168+ pages of discussions.

 

Since the time change, my devices have been loosing connection to the internet either partially or completely.  In the morning, some devices can't browse the internet, while others can only access YoutTube, but not Netflix for example.  ALL devices are connected through wifi or hardwire though to the CODA modem.

 

I've gone through each device that connects to the internet and found a few that had an incorrect date and fixed them hopeing those were the issue, but it didn't fix the problem.

 

Tonight when I go home and connect to the modem with my phone, it'll connect to my wifi (either 2.4 or 5G) but won't be able to browse on my browser, yet still receive emails using the email app.  When browsing I'll get the DNS_Connection issue or ERR_NETWORK_Timeout... 

 

A reboot of the coda and everything works fine again for a few hours until I notice something else not doing what it should be able to do.

 

I'm on my 4th CODA in the past 2 weeks.  2 Techs came and confirmed wires are all fine coming into the house to the modem.  Techs also confirmed the area was working properly too.

 

@RogersDave@Datalink  Any thoughts?  I'm on the last string before jumping ship.

Firmware 2.0.10.26T1 and 2.0.10.26T2 have been quite successful but they are interim test builds that will likely not be distributed outside of the trial program.

 

We are currently working on firmware 2.0.10.27 which additional performance improvements. That firmware should be available for general release after completing our internal validation and testing with the community. Before someone asks, I do not have the date or release notes yet but I expect this firmware in the next 2 weeks.

That's great, I assume teh additional performance improvements are going to help with gaming (latency/packet loss on upstream).

 

Firmware will be ready in 2 weeks, but do you know when trial participants will be able to beta test .27? I can't wait to give that a shot.

@RogersDave

I really hope this fixes the issues.  Since the time change my devices would lose the ability to access the web either partially or all together.  All of my devices will connect to the CODA properly either via wifi or ethernet, but some of them won't be able to access the web at all; others are able to access youtube but not netflix for example.

 

My phone will connect to either 2.4 or 5g wifi connections no problem, but won't be able to browse to any website, getting the DNS NETWORK or ERR NETWORK errors.  Although using apps to access content works.

 

Other devices will have no access at all.


The only fix is a reboot of the modem.  

 

I'm on the 4th modem in 2 weeks, with the latest one being on the "latest version" of firmware.  I've also had 2 techs come to the house to only confirm that things are working then and there, but by the end of the day some devices are rendered useless.

 

I've found a few devices on my network with an incorrect date, but fixed them hoping this would solve the issues... it didn't.

 

I'm tired of rebooting my modem at least once a day.

Re: CODA-4582 - Open Issues for Investigation

I'm getting a bunch of these errors.

 

No Ranging Response received - T3 time-out;CM-MAC=64:77:7d:ff:ff:ff;CMTS-;CM-QOS=1.1;CM-VER=3.1;

 

B-INIT-RNG Failure - Retries exceeded;.......

 

Lost MDD Timeout;CM-MAC.......

 

Where the MAC Address is the same as the CODA box.

 

Obviously this isn't normal.

What are your signal levels like?

Re: CODA-4582 - Open Issues for Investigation

log in to the modem and go to "DOCSIS WAN" post the signal levels here please. Also go to the DNS settings page on the modem and set it to manual, then enter these values:

DNS 1: 8.8.8.8

DNS 2: 8.8.4.4

DNS Settings were changed to the Manual IPs you provided.  Once the change was applied I couldn't browse the web anymore and instead on my browser got: DNS_PROBE_FINISHED_NXDOMAIN

 

Same error when I'm experiencing the issue on a regular basis.

 

Had to remove the DNS settings and reboot the modem in order to browse again properly.

Re: CODA-4582 - Open Issues for Investigation

@belowme you're missing the DOCSIS 3.0 Downstream channels from 9 to 32.  Are  you running an original CODA-4582 or one that has a single or double black dot (round black sticker) near the power cord of the modem?  In either case, the missing channels would suggest severe cable signal issues.  Two things need to happen.  

 

1.  If you have an original CODA-4582, you should swap that for one that has a single or double black sticker which indicates that there is additional shielding above the DOCSIS cable tuner.  That is designed to prevent 2.4 Ghz wifi interference with the DOCSIS tuner which results in missing cable channels.

 

2.  Call tech support and ask the CSR to run a signal check on the modem.  With your current DOCSIS 3.0 channels, that should fail automatically, leading to a tech visit at your convenience.  When all is said and done, can you repost the signal levels, just to see how they turned out.
