Strange Disconnects Cutting Off Internet Access

If you could disable IPv6, enable remote access and then let us know when it next happens but don't reboot or try to fix it in anyway so we can have a look at that time that would be really helpful!

IPv6 is already off via LAN, let me know if you need it off on WAN as well. I just turned on the remote access. I'll try not to reboot but I can't make any promises as everyone uses the internet here seemingly 24/7. 

Also, most things on my network are assigned an IP. if they end up having a question about a device or a specific IP address, let me know. I can most likely tell you what device that is if they can't already see it. .

We would need if off for WAN as well. It's unlikely we'll be able to match up but if you have everything ready then it'll make it easier should it happen again.

Just to ensure we can gain access when needed if you could:

  1. Ensure the R3 is in the DMZ on your ISP modem/router or the ISP modem/router is in modem/bridge mode
  2. Disable IPv6 in WAN/LAN on the R3
  3. Enable remote support on the R3
  4. Post back here when you've done that

The team can then remote in at any time, no need for you to be present.

With Verizon Fios I do not have any router/modem. Just their ONT which I don't believe I have any kind of access to. If they want to try at their convenience and we can see if they have access and figure what can be done if they don't. Configuration is exactly like this:

Fios ONT -> R3 -> dumb switch -> wired devices on second floor 

                        |                |  -> dumb switch on first floor -> wired devices on first floor      

                        |
                        |<-> WiFi -> WiFi devices

Otherwise everything else is done.

That's great thank you, I'll pass the topic onto the team so they can keep an eye on it - just post here again as soon as you notice it happening.

It's happening right now.

I went back and grabbed some screenshots and checked a few things: 

  • iPad is streaming Twitch just fine. Captured video below. 
  • Mom's iPad is working. 
  • Mac mini does not connect to Facebook or the router. 
  • Xbox was knocked offline as well. 
  • Gaming PC and Apple TV in my room were  rebooted. Did not pull IP from router. 

I also have a couple screenshots form the other Mac of Facebook and the router not able to connect. Will update when that machine is back online.

Looks like we had an uptime of about a week. Just discovered my wired devices are currently disconnected and it appears the outage started around 3-4am my time. 
 

Attached a current screenshot of the network and logs from the cgi-bin path.

 

@Netduma FraserAny update on this? I know you had passed it off to the team but I haven’t heard anything since.

Sorry for the delay and thanks for the new logs, I think they're going through all the logs from various people and looking into who they need to remote into to investigate further. Could you provide the router MAC address please? There may be some logs/errors we can see that way

No problem and I'm always happy to provided a log if I can catch it in time.

It does look like someone did something at some point as when we were at the height of the crashes last week I was checking logs constantly. Plus we've had stability until last night so something changed about a week ago. 

This is the MAC address from the WAN settings (under cloning): 44:10:91:67:6d:65 

Let me know if this is the correct address or not.

Need to reboot but before I do I wanted to pass along the last system log as well as a cooked screenshots. It looks like things are trying to reconnect and if they had an IP at one time it's still showing. Granted, almost everything is assigned an IP. However it's just not being assigned an IP on the client side.

Ethernet. I basically just pulled the switch cable over from the XR1000. If the device has WiFi I probably already had it wired up from the XR1000 and never bothered to redo the Wifi connection as we normally don't use them unless it's something like a tablet or a HomePod or something like that. 

The DHCP server is still enabled as I do have a few things that I'm letting use it.

Interesting, if you find the device in the offline section does it give it an IP or is it blank? Does the MAC address there match the MAC address for the connection method on the device?

Yes if it's assigned. So for example the desktop Mac I'm typing this on uses the wired and wireless connections (location services don't work without wifi). They always show the correct IPs and the MAC addresses are correct. I assigned them via a spreadsheet I kept from when I did the XR1000. As far as I can tell they're always correct / matching as intended.

The only ones that do not show any IPs are the ones that may have timed out as they're things that are hardly used or the DHCP lease itself has expired. Attached Screenshots of the Mac Mini and the gaming PC. I haven't used the gaming PC since last night and while I did turn it on earlier to see if it would be assigned it's IP and it was not. Otherwise, I'm not sure of there's any other timeout on that aside from the DHCP lease expiring whether it's assigned or not.

iPhones, iPads, annd one Galaxy phone aside not that I’m aware of. I’ve already turn them off there so I can assign them the IPs.

The connection issues? Completely random. There seems to be no rhyme or reason as to when or why they happen that I can find. 
 

I’m wondering if something is flooding the DHCP server or some other part of the router at some random interval and it’s causing some part of the software to crash and not reboot on its own. 
 

Just looking through my logs my suspicion is my security device with the IP ending in .90. I just don’t know what I don’t know in terms of reading the logs to understand if that’s correct or not. It’s just the thing that stands out.

Is it once a day or more than once a day? DHCP can handle a lot more devices than that and not seeing any errors that would indicate that to be the case or a specific issue with that device. However, extend the lease to 10000, save, reboot from the interface, wait a few minutes then see if you get more uptime. If not, ensure everything has the reserved IP then disable DHCP entirely and see if that helps.

Generally it’s once a day but like I said, it’s also random. As you see in this thread it can happen 2-3 times a day at worst and then we get long periods like this one but it doesn’t seem to last more than about a week. I believe we just passed the 24 hr mark on this reboot so we’ll see. 
 

And I agree, DHCP should be able to handle more devices and like I said, that one device only stands out to me because it seems to flood the router. So if DHCP itself isn’t crashing maybe something related to it is. As I noticed yesterday while I let it sit before I rebooted it, things do try and reconnect and the router does see them but they never get assigned an address regardless of assigned or via DHCP.
 

Also, I noticed things do get their leases renewed with no issue that I can see. 
 

Other wise I’ve been looking for some other “golden path” to make this happen but it usually just happens in the middle of the night or while we’re doing normal things. 
 

I’ll go ahead and assign addresses to things that need to be on the network and just turn off DHCP and see how far we get.

Update:

I've assigned the needed IPs for the couple things that may be needed and turned off DHCP. I've attached screenshots of all the things that have assigned addresses and removed the ones that do not (an odd HomePod and an old Android tablet rarely used). This way you can see all devices total that connect to the network, that  connect to the network infrequently (consoles, a few other things), or have't quite decided that they no longer need to connect to the network (XR1000, old smart plugs).

I also attached a screenshot of the Mac Mini's ethernet panel when the connection is working so you can compare to when it isn't.
