The power went out in my house today, so the router was forced to reboot. Were there any temporary settings set by you guys that I may have lost? Also, I noticed that a new firmware was released. Do you recommend that I download and install it?

I wanted to confirm that it still hasn’t crashed. May I ask what changes you most recently made? I think they worked.

I don’t remember what symptoms preceded the crash, but it hasn’t crashed in a long time at this point, so something is going well.

Something crashed about an hour ago. I rebooted the router and it’s back to normal.

It crashed again 7 minutes ago. Both of my devices retained their IP address but couldn't connect to the interface.

It just crashed again about 5-10 minutes ago. My iPhone lost its IP address and could not reacquire the reserved address. My PC retained its reserved address, but couldn't open the interface and couldn't ping the router.

I lost internet connection again this morning about 95 minutes ago. It presented the same way, losing internet as I went to start a video on my phone. My PC was off at the time. I disconnected my phone from WiFi for at least an hour, reconnected it, and it reacquired the same reserved IP address as before. When I booted my PC after 1 hour, it failed to acquire its reserved IP address. Using my phone, I rebooted the router via the DumaOS app, and now my PC acquired an IP address, and everything has an internet connection again.

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.

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.

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?

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

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.”

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.

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?

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.
