Seems fixed, so any details on what the issue was? @Adam1712 @Jshow10is it fixed for you guys ?

I'm going to try now.

@Netduma Fraser Any news ?

I hope so, because I haven't been able to use the router's ability for weeks now. Anyway, keep us updated, please, and maybe ask them what caused this if it's solved—just out of curiosity.

No

And yeah, the bandwidth is low because only my PC is connected to the router, and it's streaming a twitch livestream. Still, it's a big coincidence that the CPU usage spikes out of nowhere for no apparent reason just before everything stops working.

And I swear to God, if it finally starts working again, I'm never touching that interface ever again! Hahaha

Not really, and it logs itself out after maybe 30 minutes, I believe. I feel like I'm asking a lot here, but in your opinion, what should be enabled or disabled on the ISP router and the NG to make sure it's not just a misconfigured setting?

Me again lol. Sadly, I spoke too soon. The issue still remains, but I've noticed that with every disconnection, there is high CPU usage, before the drop it seems like. I recorded my screen and captured when the CPU usage started peaking—at that point, everything stopped working. Twitch, which I use to monitor bandwidth stability, froze, and even a simple Google search wouldn’t load. You can see in the recording that nothing was working except PingPlotter, which was still pinging Google just fine. Then, when the stream started working again, the CPU usage dropped. Btw the router is not hot also there isn't any drop when in AP mode

I don't want to talk too fast, but I might have found the issue. It's this little adapter that I've been using with my router for about 2 months. I've had this adapter (https://amzn.eu/d/7LInO1C) on my smart TV , but I decided to put it on my PC about a month ago. Everything seemed to work well for those 4 weeks, or I might not have noticed the disconnections, to be honest. But like two weeks ago, I turned off/on the XR1000V2, and that probably messed something up. Naive me would have never thought that a small adapter could mess with the entire router and all the devices connected to it. But since I removed it, there have been no disconnections. I don't know if you have any explanation for this, but my theory is that the USB (maybe some sort of power saving mode) lost connection , and the router thought the WAN was disconnected somehow. That also explain the lack of logs on both the main isp and the XR router I have a 1Gbps connection, and with the XR1000V2, I only get around 500 to 600 Mbps max wich is normal I believe. But with that USB adapter, I had 800 to 900 Mbps, even with all DumaOS features on. So, yeah I'm about 80% sure that was the problem. Thanks for your help, man!

I mean, I’ve tried everything—different RJ45 cables, timing every disconnection (no pattern), another phone, a laptop. I tried plugging the router into a different wall socket, resetting the NG, resetting my main ISP router, changing DNS, and everything you suggested. What’s weird is that during the disconnections, I still get a ping with PingPlotter to Google.com. I’m so desperate I even tried a specialized version of ChatGPT in networking lol

I just had another disconnection, and the DHCP server was disabled. My phone and PC IPs were reserved with the correct MAC address, but it still disconnected for a minute. It’s a mystery—out of nowhere, it does this. Nothing has changed in my setup since I bought that router a few months ago, and I haven’t had any problems until now. Do you have a recommendation on which version I should downgrade to as a last resort? And maybe a link to it, please?

No

I already tried this, but the issue remains. I also set up IP reservation for all my devices but the issue still remains.
