R2 loses all connection periodically, requires unplug

[The0dark0one]

I was wrong about the Discord issue. It has resurfaced as well.

[Netduma Fraser]

Did you disconnect your iPhones from the network and seen whether the main issue seems to be fixed?

[The0dark0one]

Not yet, I’m on break from work till after New Years so I’m using WiFi often. I will test that after I return to work early January.

[The0dark0one]

The router hasn’t crashed in over a month while my wife’s iPhone 11 was disconnected. Ever since I set the traffic filters to allow all data to the iPhones, xboxes, TV, I reconnected my wife’s iPhone, and we have continued to not have any crashes or strange behavior.

if I had to guess, I would assume that adding the traffic filter rules to allow all traffic fixed everything.

Great to hear that and thank you for the update!

Update: I didn't realize it, but I hadn't reconnected my wife's iPhone. After I reconnected it, the crashes have returned. It would seem that her phone is specifically what is causing the router to crash. Also, her iPhone is actually an iPhone XR. My phone has been connected the entire time, and we went months without a crash. As soon as I reconnected her phone, the crashes returned. The crashes were occurring despite adding traffic filters rules for her phone to allow all traffic.

These are my current conclusions:

• Discord works consistently on my iPhone 12 Pro when a traffic filter rule is set to allow all traffic
• My wife's iPhone XR will cause the router to crash regardless of traffic filter settings or QoS settings
• Samsung TV Plus https://www.samsung.com/us/televisions-home-theater/tvs/tvplus/ works fast and consistently only when QoS is disabled.

Next steps:

Would it be possible to log all traffic from the iPhone XR using traffic filter rules to diagnose when crashes are happening?

Thanks for the update, we can setup remote logging so when the crash occurs we can have a look at what is happening - we'd have to do that on Monday now. Is there anything different between your phones that you can think of (other than model) such as what kind of apps they use or what is downloaded/uploaded?

[The0dark0one]

I was looking into that yesterday, and I couldn't find much. I thought perhaps it could have something to do with iCloud, because I know that is supposed to be backing up a ton of data. That's where my intuition is pointed right now. She has a 50gb iCloud account that is completely full of photos, messages, and iPhone backups. I have all of that disabled on my phone. 

[Netduma Fraser]

Interesting, if it's uploading huge amounts of photos/videos etc then it could have that affect - we've seen something similar with one user uploading a lot to Google photos

[The0dark0one]

So I can now confirm it isn’t simply related to her iCloud and backups. The router recently crashed while she was just starting a Netflix show. I can guarantee that it wasn’t related to backing up data because I have set the phone on low data mode which says “when low data mode is turned on, automatic updates and background tasks such as photos syncing are paused.”

Thanks for the information, lets get remote logging sorted, could you disable IPv6 in LAN/WAN then enable remote support and we can get that done for you tomorrow

[The0dark0one]

All IPv6 is disabled and remote support is enabled as of noon yesterday.

OK that's all enabled for you, if you could please let us know the next time it happens we will have the full logs.

[The0dark0one]

Just to be clear, did you want me to disable the WAN IPv6, the LAN IPv6, or both? WAN was already disabled, but the LAN was not.

 

EDIT: also, it keeps doing this: daemon.err odhcp6c[3683]: Failed to send DHCPV6 message to ff02::1:2 (Address not available)

Sending a DHCP message to a v6 address, despite v6 being disabled?

Disabling IPv6 was just for us to get access to the router, we've got that sorted now so no need to change IPv6 again. That is something we're away of, it's a normal log on that version and will be fixed.

Ok, I’m pretty sure it just crashed about 15 minutes ago. I think my phone caused it while I went to play a YouTube video. My wife was asleep so I doubt her phone did anything.

[Netduma Fraser]

Okay great thank you very much, I'll get the team to check the remote logs on Tuesday!

Hey, welcome to the forum!

Could you make a new topic for your issue please so we can focus on you there. In the meantime disable the Private Addresses option for the WiFi on your iPhone for the R2 network.

[ben8401]

I have deactivated the private wifi as you said it seems to remove the problem on a small problem to be settled at the next update of R2 

[ben8401]

I created a topic, it crash
ed again

[The0dark0one]

it just crashed again about 10 minutes ago. 

It seems like crashes are happening more often while IPv6 for LAN is disabled. I haven’t changed anything and I went from 1 crash in a month to crashing every other day it seems. I also enabled a DNS override instead of using upstream DNS.

What’s also interesting is that, previously every device in the house used to lose access and nothing could get an IP address anymore. I’ve since manually reserved IP addresses for each device. Surprisingly this has allowed some of my devices to stay connected with their own IP address, but receive no internet access. 

Even right now, I can access my router’s interface from my phone still. I disconnected and reconnected and it still received the same reserved address. Despite all of this, the router isn’t sending internet to any of my devices.

I tried the same thing with my PC over Ethernet, and it refuses to give it back the same IP address. It just gives it the error IP address of 169….

The connection dropped just as I was starting a new YouTube video, like usual. It does the quick initial buffering of ~30 seconds of video, then it crashed.

Anyways, I mention all of this because it happened like this a day or two ago, and the router was able to complete it’s built-in speed test just fine, but none of my devices would receive an internet connection.

EDIT: after a reboot, my PC receives the reserved IP address again, but still no internet for any of my devices. The Connection Benchmark still works fine according to the router.

EDIT2: I re-enabled IPv6 for LAN, then rebooted through the interface and now my connection has been restored to my devices.

Thanks a lot for the information, this will go a long way in helping us nail down this issue once and for all.
