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.

@Netduma Fraser It still happens when "Disable Port Scan and DoS Protection" is enabled.

My bad man ahaha @Netduma Fraser

One disconnection occurred from 21:06 to 21:08. Here are the logs after I cleared them at 20:41:01. Should I try to roll back to a previous update? Before I updated to the latest version, I was on V1.1.0.16, and I also had those disconnections, so maybe I should try one version before that.

Finally had time to test with my ISP router in bridge mode, and it's still happening... What should I try next ?

Thanks for your response again, I already put the IP address of the XR in the DMZ tab on my main ISP router. There's also a DMZ setting in the WAN setup on the XR—do I need to touch this? Because I tried adding the IP of the XR, but it says, "DMZ Server is not on the LAN subnet." And I was about to try in bridge mode

I've already checked, and no events are shown during the disconnection. However, I found log entries from my ISP's main router that coincide with the disconnection, but similar entries also appear when everything is working fine. here they are

I just did that, but I'm still having the same issue. The connection drops, but PingPlotter can still ping Google just fine. However, if I try to access Google via a browser during the disconnection, it doesn’t work. And no problem with AP mode

Currently testing AP mode to see if the issue persists. So far, everything is stable, but I’ve lost access to DumaOS features, which I need.

Main Router: Technicolor CGA4233 (connected to ISP) Secondary Router: Netgear XR1000v2 (WAN port connected to Technicolor LAN port, not in AP mode) Devices Affected: PC (wired to Netgear), Phone (WiFi on Netgear) Issue: Several times a day, for a few seconds, websites (YouTube, social media, etc.) stop loading. However, PingPlotter still shows normal ping, and Speedtest reports full speed even during the drop. The problem only happens on devices connected to the Netgear (both wired and wireless). Devices connected directly to the Technicolor router work fine. The issue started after I powered off the Netgear using the hard button and restarted it. That's the only interaction I had in a month with the netgear, so it might just be a coincidence. What I’ve Tried: ✔ Testing the Technicolor router directly – works fine ✔ Restarting both routers – no fix ✔ Factory resetting both the Netgear and Technicolor – no fix ✔ Setting a static IP for Netgear on Technicolor – no fix ✔ Disabling Double NAT by putting Netgear in DMZ on Technicolor – no fix ✔ Changing DNS settings (Google 8.8.8.8 / Cloudflare 1.1.1.1) – no fix ✔ Tried upgrading Netgear firmware to XR1000v2-V1.1.0.22_2.1.34_HOTFIX, but the file is .CHK, and the user manual says it needs an .IMG file, so I didnt risk bricking the rooter. I don’t want to use Bridge Mode on the Technicolor (I need its WiFi), and I don’t want to enable AP Mode on the Netgear (I need its gaming features). Looking for Suggestions: Could this be a routing issue on the Netgear? Any other settings I should check? How do I install the firmware update if the router expects a .IMG file but the update is a .CHK file? Should I try rolling back to an older Netgear firmware version? Any help would be greatly appreciated! 😊

Before I started the update, it said I should not have restarted the router during the update, but I just took the risk, and it worked. Thanks for the support anyway, man. But I'm still on the v.xxxxx.16 update, so yeah, the update didn't work. Do yout think I should try again ?
