Another DHCPv6 Missing Required Option 82 and 24 Plea for Help

Just gout done with tech support chat for the same errors and connectivity issues.

I went through the usual troubleshooting, reinitializing the modem, etc with the tech. I showed him the error log and according to him:

"The DHCP error will not occur anymore" I asked if they just troubleshot it or if they actually made a settings change and his response was "DHCP may fail to configure the client in proper way, It can't communicate with any server and you will loose the internet connection for a while and then it gets back on. That was reset from our end."

I guess only time will tell.

Hopefully that solves the issue for you. Since mine is giving the dhcpv6 errors every hour (when the ip lease tries to renew) I could tell after an hour without the errors :)

It's so frustrating to know this dropping of connections daily is a configuration issue on their end, but we still have to jump through hoops and reset everything before they consider that the issue is on the backend side. Mine still hasn't been "reset" on the comcast side :(

I suffered similar issues.  Here is what happened: 

Arris Gateway SBG8300 providing 1GB service at my home.  I

11/04/2022 - Xfinity service outage for network maintenance, was down for about 6 hours.

11/05/2022 - Late evening, internet service in my home stopped abruptly.  Performed the following troubleshooting:

• Checked Xfinity mobile App for network outage.  Result:  NONE
• Checked my utility company's website for power outtage(s) within 5 mile radius.  Result:  NONE
• Xfinity's app is not able to connect to the gateway with no internet, so I had to do the old school troubleshooting.
  • Powered down computer
  • Power cycled gateway by doing the unplug power supply for on minute then pug back in.  Result:  NONE
  • Unplugged coax cable for 10 minutes then plugged back on.  Result:  NONE
  • Powered computer back on Result:  NONE
  • These 4 actions were repeated twice further, 2 hours apart.
• Accessed event log on gateway for further investigation.  Results:  CRITICAL INFORMATIONAL EVENTS.  MANY.  Each of the events logged below appeared hundreds of times, causing my gateway to have 76 pages of events logged, just for one day.
  • Google searched each of the persistent critical errors below and saw nationwide occurrences with zero fixes, and no legitimate explanations.
    
    • DHCPv6[15451]: 72001011-DHCPv6 - Missing Required Option 82  Critical 
    • DHCPv6[15451]: 72001011-DHCPv6 - Missing Required Option 24   Critical
    • eRouterEvents[12677]: 72003004-eRouter enabled as Dual Stack   Informational 
    • DHCPv6[14937]: 72001004-DHCPv6 Provision - 0 Retries Attempted with Last attempt at XX/XX/XXXX Critical +
    • DHCPv4:  72001001-DHCPv4 Provision Completed  Informational
  • Most of the 100+ threads I scoured over with customers experiencing these same issues have been told their gateway/modem/router needs to be replaced.  Many of them did so.
  • Only 2 customers posted that their connectivity issues were solved with the telephone agent editing the boot loader.  Unfortunately, no further details were available on the boot loader.
  • 5 customers were advised by the telephone agent that the source of these critical events was internal.  Xfinity had tried to roll out an update that contained errors.  These errors prevented the complete implementation of the update.  
• Called Xfinity's for technical assistance.  I let each person know I had worked for Microsoft previously, and some of their scripts they follow could be bypassed or if further escalation was required.
  
  • Call # 1 - While in the middle explaining the situation above, the call was disconnected.  Unknown if it was accidental or deliberate.
  • Call # 2 - Provided the second agent with the details of the issue affected me and others and what remedies I had been able to find.  He was not able to do anything on his side and scheduled for a service technician to come to my home same day.   I received a text message reminder for my install (not for my service) appointment.
  • Call # 3 - The 3rd agent advised that the text notifications do not differentiate between install and service so they only include the word install.  We went over in great detail the issue affected me and thousands if not more.  He was able to go in to the boot loader and attempted to make some changes but they kept failing.  I was able to see the events logged on my side.  After 20 minutes he advised he exhausted his options and that the service tech would be able to dive deeper for root cause.
• Service technician showed up.  Explained my issues and errors, that it is happening nationwide, customers have unanswered questions or unresolved problems, and that I had gone through severazl hours of gathering examples, documents, and more while waiting his arrival because I was not going to simply be told, get a new gateway.
  • Existing gateway SBG8300 showed connected to Xfinity's network, but blocked from online access.
  • I still had the prior gateway SBG6900-AC which the service technician was able to remotely connect to the network, install a few firmware patches that Xfinity does not allow customers to do themselves.  Result:  SUCCESSFUL CONNECTION

So in a nutshell, Xfinity is rolling out project Genesis (you can find it online for yourself) which is combining the IPv4 and IPv6 (hence the erouter as dual stack even logs) to this new standard for faster 5G and 6G down the road.  No project is without problems. With the vast number of devices out there, the more unique coding that has to be done for devise and line limitations or incapability (whether it was known ahead of time or not).  And some equipment may not be able to get a planned update because it may already be or will soon become obsolescent due to its lifecycle.

I dont know if my semi new gateway is on a not yet published chopping block or not, but tech support should really be trained to do more than just do less than the bare minimum in order to open the sales pitch door for equipment upgrade.

I have this exact same problem and errors. Similarly work-from-home and drop during the most inappropriate times for meetings, etc. causing complete lack of internet connectivity. What is the protocol to request this support? The automated assistant is worthless even when listing the exact error.

Please create a new topic of your own here on this board detailing your issue. Thanks. The original poster has not returned. 5-month-old dead thread is now being closed.

For future reference, it is better to submit your own post as it creates a ticket to get help, and posting on an old thread can delay getting help.
