RunningMan:

Tried disabling IPv6?

Hey, someone else is getting the same issue as me! I'm still happening intermittently! Last issue was at 7:40am on the 5/10/2021.  The only fix I have found so far is to connect to the router when it happens and click "Reconnect" in the Online Monitor screen. Reconnecting fixes things straight away for all devices on the network. I was just thinking yesterday that maybe I should disable IPv6 and see if that helps.

I didn't have bad help when I called 2 degrees to try troubleshoot it, they just weren't able to fix things. 

I can only assume Chrome is A/B testing their user mode networking like DNS over QUIC or something and it is not playing nice with 2degrees at least.

It's not chrome, this happens regardless of the browser being used. I'm just going through the fritzbox logs now and think I see a pattern where this occurs about 3-5 minutes after 2Degrees pushes settings. Just looked at the logs 

Example of the event sequence - It starts every time with "The service provider successfully transmitted settings to this device.":

Please don't suggest this, better we fix the issue than just ignore ipv6

Temporarily. It's a legitimate troubleshooting step for some issues. If reverting to IPv4 resolves the issue, then it's narrowed down where to look for the problem. Can't fix an issue if you haven't completed any troubleshooting to determine where the problem lies.

I disagree these days. I run a full dual-stack network where the majority of my internal network is IPv6 also and know when my IPv6 goes down, it just means everything works over IPv4.

I can't say I've experienced any issues with IPv6 that I have not also seen on IPv4 on 2degrees in years now.

Please don't give advice to disable IPv6, @RunningMan. Modern IPv6 virtually never breaks anything (browsers attempt connections on v4 and v6 almost simultaneously, see "Happy eyeballs"), and ignorant users who leave it off are likely to be cut off from the modern internet and and IPv6 only services as those begin to appear. Also, there are times when IPv4 breaks and v6 doesn't, leaving users on the modern internet connected and the legacy internet disconnected.

mrdrifter: @hungugu are you able to check your router logs and see if you have the same pattern of issues where they appear to correlate to having settings pushed out from 2D?

Will do, let me see if I can get the log right after I experience the issue.

Mine just dropped all my active connections this morning in the middle of a call with downloads running and a couple of tabs loading. Everything completely dropped and took about 30-60 seconds to come back up. Log shows that settings were pushed to my Fritzbox about 15 minutes ago.

Bumping this because I switched from Slingshot to 2degrees and now getting this issue.  Erx router and unifi AC. Like others it would come in clusters and and a router restart would scare it away for at least a few hours.

I'm thinking it's DNS as it's really the only thing that changes between the two vocus isps.

Have switched the DHCP over to google DNS and haven't seen the issue pop up since doing that (last night).

Will follow up this how I go over the next few days....

which 2degrees DNS servers are you getting passed from the network?

Not sure it is actually DNS, got the issue last night and this morning.  Next option is router swap out. Above that, hassling 2degrees and wiggling out of my year term if I have to.

michaelmurfy: And is your Edgerouter up to date firmware wise?

I’d also recommend using the 2degrees provided router instead given the Edgerouter is basically an abandoned product now from Ubiquiti. The issue is almost entirely due to your home setup and my guess will be with how you’ve configured MTU.

2degrees and Vocus support a full 1500 MTU. Refer to the Edgerouter guide I wrote years ago with how to configure this.

I had actually rolled it back a hotfix as I had originally done the silly thing of change two things at once (firmware and ISP). Have updated it again today. The MTU is 1500. I used your guide when setting it for Stuff Fibre originally.

The supplied router is an Orbi 6 (which I don't have) and is fairly meh but all accounts, the main reason I have the Edgerouter is the hw offload (which I will turn off to see if that is an issue) so I can actually get advertised speeds..

Weird you would say it's my network when two other vocus isps, Stuff Fibre and Slingshot, were both 100% ok  and as soon as I move to 2Degreees it starts having issues?  I think my ERX had an uptime of like 100 days on slingshot I had so few issues.

I do plan to dump the ERX for the reason you mentioned, also seems it's turning into a security nightmare (I seem to be getting a lot of security hotfixes...). I have the old Asus Stuff fibre gave me that I will try.
