DHCPv6 - Missing Required Option 24 & Option 82, lagging internet, then IP Address Released

Strange, have you tried isolating the devices that you have connected and confirming that all of the software is up to date on them? Or trialed having only the necessary devices connected to your network and then gradually adding them back on to see if any specific device may be causing the issue and drops? You mentioned noticing it happen while gaming with others in the evening, when was the last update with the gaming software and is it with specific games or chats?

I'm happy to run a few tests to confirm the connection to your home and signal strength with a packet test to the equipment. Also, if you have the logs from the ping and traceroute we can investigate together where the drops are happening in the transmission. Please let me know if you'd like to run additional troubleshooting after checking the devices in the home and the gaming software.

Hi XfinityXanadu,

I appreciate your response.  The issues I'm facing have nothing to do with anything attached to my network.  A technician came to my home and after I showed them the router logs and explained my experiences, they confirmed there have been many issues within my neighborhood after Xfinity upgraded the system.  It seems my neighborhood has a lot of old equipment, and that old equipment is not communicating with the new system very well.  They swapped out my old router and placed a few tickets to have some other things done.  For example, the box across the street that carries the connection to my home was smashed and badly damaged.  That was replaced.  The connectors from that box to my home is completely corroded, this issue has not been resolved yet.  There is also an order to re-dig the cable line from the box to my home, this has not been completed yet.  Meanwhile, my issues continue to happen.  I cannot say if the issues are getting better or worse.

I'm going to add that when I'm experiencing connectivity issues with my internet, my TV freezes and sometimes loses connection as well.  This issue has to do with the communication between Xfinity and my home.  After looking at other sites, I have found that a large number of people in my area have been experiencing and complaining about the same problems.  I'm not convinced that replacing my cable running to my home will resolve this issue, but replacing the corroded connectors may help.  I strongly believe that the upgrade to the Xfinity systems in my area is the primary cause behind the problems.

This looks like a recurring issue with Comcast.  Here is one from last year that doesn't show resolved:  https://forums.xfinity.com/conversations/your-home-network/symptom-cannot-reach-url-dhcpv6-missing-option-24-and-option-82-persistent-cable-model-event-error-logs/622cf2e26c4cd02237d454e5

What's going on?  You couldn't renew a DHCPv6 lease from 1:57:43 till 2:05:39.  That's a long time. 

Under normal conditions on a network that works fine, you release the lease before trying to rebind/renew.  Normally, you wouldn't notice anything in human time.  If your gateway does that, and then cannot contact a DHCPv6 server, the routing on the internal clients is messed up because you have no gateway during the time it's trying to get a lease.

It's one of these:  https://forums.xfinity.com/conversations/your-home-network/dhcpv611922-72001011dhcpv6-missing-required-option-82-24/649d8b8cce76231eba55f1e1

Why, dunno.  Xfinity DHCPv6 server unavailable at that particular time, over subscribed, under attack, the requests are timing out due to a route change on their side, or maybe either you or the DHCPv6 server just rebooted perhaps.  Could also be you've got something going on with poor signal either in your house, or upstream from you that isn't helping the situation any.  It might be helpful to go through this to make sure.  See if anything applies and take a look at signal power/errors/SNR etc:  https://forums.xfinity.com/conversations/your-home-network/internet-troubleshooting-tips/602dae4ac5375f08cde52ea0

You don't have a lot of options on most modems and 3rd party gateways for controlling or debugging the DHCPv6 conversation, and no options at all on Xfinity equipment.  At my location, when IPV6 is messed up, or when they are doing "upgrades" in the area, I just disable IPV6 entirely and run IPV4 only.  I leave it that way until I no longer see any Xfinity trucks around and the default lease time on IPV4 extends out for a few days at a time.  I've noticed IPV4 leases shorten to hours if they're working on stuff, and you are also likely to change external WAN IP addresses during that time. 

Not an ideal workaround, but sufficient at my location.

You might have made a post that got marked private.  Private info, phone number or email, MAC address will do it too.  Looked like you tried one but the bot could be hiding it.
