Random disconnects with new firmware

[Achilles]

Anyone else experiencing this?

Ever since upgrading the firmware I've had the router disconnect all devices from the internet for seemingly no reason. One night I had to reset the thing 4 times. 

I thought this issue was fixed?

Would you be able to grab the log when this next happens please before doing a reset? By reset do you mean factory reset or reboot? So it doesn't reconnect on its own?

The team are keen to get to the bottom of it, so if needed, would you be willing to enable remote access so the team could potentially remote in to take a look when it happens?

If so, please:

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 and when the disconnect happens (on Monday if possible, they're not available at the weekend to look)

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

Will grab the log next time and no, from what I've seen it doesn't reconnect. The internet light remains lit though. Turning it off/on via the power button on the back fixes it but then there's no set time how long it will last for; could be minutes, could be a week.

Have no issue with you guys remoting in if necessary. I don't have a modem or anything connected with the router so would step 1 still be needed?

@Netduma FraserThis issue is happening to me as well. Just thought letting you guys know. I tried factory resetting R3 but it was of no help. All my devices gets randomly disconnected twice a day. 

[DeeKay_FPS]

@Netduma Fraseralso I noticed , When i switch off stready ping , it automatically gets switched on when I check it.

No step 1 wouldn't be needed in that scenario

If you're happy to allow remote access please do the above steps and let us know when you've done it. 

We're aware Steady Ping can become re-enabled, we'll be fixing that and defaulting it to off in probably the next update.

Hey man, I was out at the time so couldn't grab the log but it did happen again.  Appears it might be when my wife starts her live stream on her desktop. Doesn't happen every time but every time it's happened she has just gone live. 

 

Just fyi she is connected the following way:

Router > unmanaged switch > smaller unmanaged switch > desktop

This was the setup with the R2 and never had this issue

I'll try get the log next time

[Netduma Fraser]

Okay interesting, is it possible to try without the switches or is it not possible due to the distance away from the router?

Not really possible unfortunately

[Netduma Fraser]

No worries, is the livestream setup to be prioritized on SmartBOOST at all? Could you disable the protection options in Troubleshooting > Advanced and see if that helps please.

All advanced troubleshooting protection points are off already. Only one on is Allow Ping.

Nothing is on SmartBOOST

Just had it disconnect. All wired devices died but wifi was working. Couldn't even reach the DumaOS page via the desktop, had to do it via my phone. Find log below.

Thanks for the log, I'll pass it on. Is there anything specific you can think of that happens at the time, e.g. a particular device is connected, specific internet traffic etc?

Nothing out the ordinary. Normally just general web browsing and/or gaming via desktops or consoles, streaming on smart TV, streaming on twitch. We have close to a 1Gb line so it shouldn't be hitting a throttle either. 

 

Weirdly, even when all devices lost wired connectivity and DumaOS still reported all LAN ports as Connected

[Netduma Fraser]

Okay thanks, disable SmartBOOST/QoS entirely and then see if it continues please

SmartBOOST disabled. 

Turned off Smart Ping too. 

Nothing turned on under Troubleshooting > Advanced

 

Just had another disconnect. This time just things from the unmanaged switch. R3_2024-06-23T15_43_34.204Z_logs.txt

Again, reboot instantly fixed.

Might be the DHCP lease, if you give your devices reserved IPs then disable DHCP does it happen again?

Should that really be necessary. I never had this issue with the R2, or any router for that matter. 

Seems like a lot of hassle just to have the router do the bare minimum. 

I have a lot of devices and truthfully don't have time or patience to manually reserve an IP for each.

Sadly if this doesn't get fixed soon I'm going to have to shop around for a new router since this is becoming a big issue in the household, and I've been with Duma since the beta. 

[Proud R3 Owner]

I can say I don't even get a day uptime unless I set my AP's with a local static IP through the devices themselves. Once I do I can get the R3 to last a few days before it disconnects. Devs really need to fix DHCP, never really heard of a router requiring you to assign static IP through your devices to keep the router stable before. 

[Slamchez]

So I have a very lengthy thread over here with what seems to be a similar issue. Same thing, disconnect, reboot router, could last a couple days but no more than a week. I've tried disabling DHCP and that did not resolve it. One of my next steps was to do a factory reset as well but it seems that won't resolve it either. I want to see if there are any similarities between us that may help narrow things down: 

1. Are the devices cutting out *only* on LAN/wired or is it everything? I think you answered this earlier but I just want to make sure. WiFi still works fine for me when this happens.

2. Just to be clear, no IPs are reserved either manually on device or via the router's DHCP? I've had it Bothe ways and it still happened. 

3. Are there any devices on the network that do a lot of sleep/wake type of stuff? Like consoles that check for updates or streaming boxes that just poke their head up and drop back off? If so, are they wired or wireless? I have a handful of things wired that do this. 

4. I noticed that devices do reconnect to my router when this happens but never get assigned an IP. Have you noticed anything like that happening? 

5. Have you noticed any relatively consistent time of day? My router seems to like between 1 and 4 am generally. 

If I think of anything else I'll post.

99% of the time it is all WIRED devices, Wifi remains working. I think Wifi was cutting out back when they had other disconnect issues but the latest version resolved that. Since then it has just been everything coming from the LAN ports which dies out.

2. Just to be clear, no IPs are reserved either manually on device or via the router's DHCP? I've had it Bothe ways and it still happened. 

No IPs are reserved anywhere. - that makes me feel better that even with DHCP reservation it was still happening because I was not wanting to mess around with that. 

3. Are there any devices on the network that do a lot of sleep/wake type of stuff? Like consoles that check for updates or streaming boxes that just poke their head up and drop back off? If so, are they wired or wireless? I have a handful of things wired that do this. 

Only devices would be the Xbox Series Xs I have and maybe the TV box. None of these are new additions and were fine with the R2. I'll have to double check the consoles though and see if I've even got that enabled. Weirdly, I feel like that was an issue before but maybe Fraser can comment. All of these are wired. 

4. I noticed that devices do reconnect to my router when this happens but never get assigned an IP. Have you noticed anything like that happening? 

I'm fairly quick with the reboot however I notice that the LAN ports say connected but no connection is active. 

5. Have you noticed any relatively consistent time of day? My router seems to like between 1 and 4 am generally. 

It's usually at night, which would be from 8-11pm EST. Not sure if that's just because more people are on.

I did wake up on Friday to no Internet in the house. I don't use the R3 Wi-Fi as the signal is very weak, so I use 2 older ax11000 routers in AP mode for my wireless needs. Unfortunately the disconnects are random for me as I had a drop out in the early evening on Saturday. I do have 4 devices using assigned IPs (2 APs and 2 laptops) but only the APs have the IP static in the device settings, the laptops pull their IP automatically from the router. The thing for me is when I look at the logs I'm getting flooded by DHCP requests from the APs unless I set the IP static through the device settings. I don't use ip6 on WAN/LAN but I do use a lot of features the router has (smart boost, ping stabilizer, adblock, etc ) and security for port scans is enabled as well as STP. Not sure why the more random disconnects happen but I know there's an issue with dhcp as when I've attached these APs to other routers and not set static everything runs well until I disconnect it to try the R3.

This got me thinking and yes, this was an issue back with my R2 XR500. 

See my original post on it here: https://forum.netduma.com/topic/24359-random-disconnects-with-wired-connection/

 

Basically the same issue - wired connections died out but Wifi remained. Funnily enough, Xbox's website states: "By default, your console is set to receive updates automatically. In this mode, each night, your console checks whether any updates are available". 

I also think that this hasn't happened when I'm actively using the Xbox which would make sense since the network is active and established.

I'm curious to see if this is the same issue reoccurring - I will disable the Always/Instant On and see if this changes anything.

You shouldn't have to no but DHCP is the current theory from the devs. However, they have asked me to ask when it next happens:

1. Is it all devices
2. Is it wired or wireless
3. Can you reconnect either by unplugging or reassociation on WiFi
4. Can you reconnect if you set a static IP on your client? (I know you can access normally, you can ignore)
5. Was there heavy download traffic going on?
6. What time did it happen
7. Can you post the logs
8. If possible, can we get a wireshark capture of them trying to connect and failing

1 & 2: All wired devices - Wifi seems fine.

3. Haven't tried replugging a wired device but I can try. 

5. Heavier or heaviest most likely but nothing crazy. I've got Fios with 980/860 approx speeds, running CAT6 everywhere and I'm nowhere near that level of usage.

6. Typically nights (8-11pm EST). 

7. Posted 2 logs but will continue to get what I can

8. Would need steps for this but have no issue. 

 

Like I said in the earlier post today, this feels eerily similar to what I encountered with the XR500 initially when it came to consoles waking up to check for updates - which I believe occurs at nights. I'm going to ensure that's disabled tonight and see if anything changes. 

 

I spoke with Iain he seems to think it might be a memory leak. He told me to ask you "ask SQA to do the following:

- get remote logging enabled for your router and check each day if you're experiencing kernel panics

- have someone (potentially core developers) Monitoring your memory usage. In aggregate and also for overwatch daemon. Do this twice a day please

- finally be have a fix for this already Binx to get Achilles an overwatch with tcp seq analysis disabled please"

Thanks for this, its very helpful.

Could you enable remote access for Tech support through the settings and i can enable remote logging on your R3, There's no kernel panics happening, as they would already report to us, and your R3 would be rebooting.

I dont think your issue is memory related as we would be seeing OOM's in the logs, which are not present.

 

IMO it appears to be something with DHCP not renewing leases. If you could set a static IP one of your devices, and see if that disconnects, we can isolate the issue to DHCP.

Another theory is that it could be DPI, so maybe try disabling that in your settings and see if the issue re-occurs
