Rx39141 Posted February 21 Share Posted February 21 Hello, I am trying to fix an internet connectivity issue that has been occurring over the past month, and while doing so I noticed that my nighthawk router had an available update showing in the topright corner of the web interface. Not paying attention, I pushed the update through thinking it was the cause of my issues. Though, once my router rebooted, the firmware version changed from 1.1.0.22 to an older version 1.1.0.16. The update button still shows an available update, but for 1.1.0.16_2. Thinking this was a mistake, I went to download and install the .zip file for 1.1.0.22, but when I try to download the firmware zip, I get a permission denied error. Is this to be expected? Furthermore, I am not sure if my router is the source of this issue, as I have no tangible evidence to prove that. Though, I have an Xfinity modem that I have setup into bridged mode that connects to my Nighthawk router. If I take the Nighthawk offline, and set the Xfinity modem back to router mode, the internet connectivity issues stop occurring. This behavior is being seen on all of my devices connected to my network. Any recommendations on what else to try to fix this would be appreciated. Otherwise, I might be out $100 if I am forced to use my Xfinity modem for routing. 😕 Please let me know if there is any additional info would be helpful with this thread.

Administrators Netduma Fraser Posted February 21 Administrators Share Posted February 21 You have to unzip it and extract the .chk file then upload that to the router. It won't be the cause of an issue though. What is the internet connectivity issue exactly? Link to comment Share on other sites More sharing options...
Rx39141 Posted February 21 Author Share Posted February 21 I can't get the router firmware .zip from https://www.netgear.com/support/download/?model=XR1000v2. Im getting an XML page that shows access denied when I click the firmware version. I didn't think this was the cause of the issue, but was not sure why my router pushed me to an old version and the download page wasn't working. The connectivity issue is odd. It happens at least once an hour for all devices at the same time on both wireless signals and over ethernet. BUT when the internet drops, if I am gaming online (iRacing), the connection doesn't drop. The connection doesn't drop if I am making a VOIP call either, but I can't receive VOIP calls when the internet is dropped. To be clear, I am unable to load webpages or open apps that require an internet connection even though my active online games and calls continue to work. My wife says that streaming doesn't work when this happens. I also setup a continuous ping to 1.1.1.1 (which is what my DNS is set to) and didn't experience any packet loss when the connectivity issue occurs. When the issue does happen, webpages fail to load and the browser shows DNS_PROBE_STARTED then eventually switch to a no internet error. After 1 minute or so webpages will start to load again. I have tried a reset on my xfinity modem and nighthawk, but the issues persist. I have been keeping an eye on the system logs in the nighthawk, but all I see are frequent DHCP lease assignments, time sync info, admin logins (only mine). The show statistics section show the Up Time as if there are no internet disconnects. For example, the current Up Time is 01:03:34 (I rebooted the router an hour ago), but I have experienced the internet connection drop twice within that time. Any thoughts? btw here is a screenshot of the download page for the most recent firmware. Link to comment Share on other sites More sharing options...

Administrators Netduma Fraser Posted February 21 Administrators Share Posted February 21 I'm getting the same actually, weird, I'll have to mention it to them. It's just a security fix so nothing that would fix any kind of issues you're having. In LAN Settings, set the DHCP range to start at .50, then assign reserved IP addresses to devices between .2 & .49 so they're out of the DHCP range, apply, reboot from the interface, wait 4 minutes and see if that stops the disconnects.

Rx39141 Posted February 22 Author Share Posted February 22 I have setup the reservations and moved the DHCP range, and have not had any issues so far. Fingers crossed! So, is there something up with the way the router DHCP server works that would cause this issue? Are devices in the > .50 range going to experience this problem? Anything settings or configurations that could be toggled to prevent this from happening? I have a device that could be setup as a DHCP server if you think it would be better to keep the router DHCP server completely disabled. Appreciate any info you have.

Rx39141 Posted February 22 Author Share Posted February 22 Unfortunately the problem has occurred again. Anything else I can try? Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted February 23 Administrators Share Posted February 23 Yes I think now would be best to try it with DHCP disabled and see if it continues please, you don't need to set anything else up to use DHCP yet. As you've done the reserved IPs they should all be able to connect just fine. Link to comment Share on other sites More sharing options...
Rx39141 Posted February 23 Author Share Posted February 23 Well I tried posting the following comment yesterday, but my internet must have cut out when I submit the reply because it never posted and was stored in the comment box as a draft... I tried some other suggestions from other tickets such as disabling adblocker and configuring QoS to 70% up and down. No fix. I also disabled the DHCP server on the router this morning, applied, and restarted. About 30 minutes later, internet dropped again. I am going to try to get my network traffic mirrored onto a device running wireshark to see if I can dissect packets to see what is going on here. Anything else worth trying at this point?

Administrators Netduma Fraser Posted February 23 Administrators Share Posted February 23 If you could grab the logs from when it happens while DHCP is disabled that may help narrow down the issue more Link to comment Share on other sites More sharing options...
Rx39141 Posted February 23 Author Share Posted February 23 Here are some logs. The internet disconnect at 11:13 is when I restarted the router after disabling the DHCP server. In other news, I monitored packets from my pc over the past two hours and noticed a pattern. Anytime the internet connection goes out, I see a large number of TCP retransmissions, duplicates, and out of order packets. These also coincide with a large number of DNS queries failing to find the domain of the website that fails to load. I also noticed that the CPU usage widget in the admin page shows max usage when all of this occurs. Once CPU usage returns to normal, the internet connects again. This could mean a few things, but I am going to disconnect a handful of devices from the network to see if they are overwhelming the router, but do you have any other suggestions with this in mind? Any common culprits for eating up CPU resources on these routers? Link to comment Share on other sites More sharing options...
Rx39141 Posted February 23 Author Share Posted February 23 Disconnected all IoT devices. Internet crashed out with the same TCP, DNS, and Router CPU usage symptoms. Going to go barebones with only my main PC connected to the network to see if the issue persists. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted February 23 Administrators Share Posted February 23 With the XR range these disconnections are something we've reported to NG for years, at this point I don't believe it's our side of things and usually relates to DHCP. I have noticed you've changed your LAN IP, could you change that back to the default and see if it still occurs? Link to comment Share on other sites More sharing options...
Rx39141 Posted February 23 Author Share Posted February 23 Just switched back to 192.168.1.x. We will see if that helps, but it was actually one of the first things I changed when the issue started. Is there any where I can go to bring this issue up with Netgear? From some of the forums I’ve looked through on their side, the recommendation is to come to you guys lol. As someone in IT, I feel for you guys in that regard. Especially if internal tickets on the matter are going untouched… Anyways, if I find anything new, I will include it here.

Our devs have looked at the problem before and concluded it wasn't on the DumaOS side of things and passed that information along directly to their development team. So essentially if you were to contact them about it you'd be starting at the very bottom of the totem pole and it may not reach who it needs to to get sorted anyway. Keep us posted!

Rx39141 Posted February 23 Author Share Posted February 23 Yeah, the internet cut out again after changing the ip range You mentioned this happens with the XR models. Any recommendations on a replacement model that won't face this kind of problem? Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted February 23 Administrators Share Posted February 23 Well I'd be biased and say the R3, I will be honest though and say there have been disconnection issues, not everyone has them by any means and they're largely resolved now but the difference is we control everything so if an issue crops up it's more likely we can fix it Link to comment Share on other sites More sharing options...
AdStruffer Posted February 24 Share Posted February 24 I'm having this exact issue on my Xr1000 on firmware xr1000v2 1.1.0.22_2.1.34 Streaming serivces continue fine, but when trying to load websites from a browser on mobile, it freezes and comes back with dns probe issue. Has been happening for abouyt 2 weeks now. I have static DNS set to cloudflares DNS servers since I installed the router in July 2024. I suspect an automatic firmware update has caused the issue but I am at the limit to my netwroking skills trying to resolve this with a workaround. Update, recreated the issue and the logs were as follows: [DHCP IP: (192.168.1.4)] to MAC address --:--:--:--:--:--, Monday, Feb 24, 2025 11:39:05 [DHCP IP: (192.168.1.2)] to MAC address --:--:--:--:--:--, Monday, Feb 24, 2025 11:39:04 [DHCP IP: (192.168.1.4)] to MAC address --:--:--:--:--:--, Monday, Feb 24, 2025 11:39:03 [DHCP IP: (192.168.1.2)] to MAC address --:--:--:--:--:--, Monday, Feb 24, 2025 11:39:03 [DHCP IP: (192.168.1.2)] to MAC address --:--:--:--:--:--, Monday, Feb 24, 2025 11:39:02 [DHCP IP: (192.168.1.2)] to MAC address --:--:--:--:--:--, Monday, Feb 24, 2025 11:39:01 Link to comment Share on other sites More sharing options...
Rx39141 Posted February 24 Author Share Posted February 24 I doubt it is the firmware, as I’ve been on multiple versions since the issue bubbled on for me. Link to comment Share on other sites More sharing options...
JustWantIT2Work Posted February 24 Share Posted February 24 I have the same issue. Internet dropping on both wifi bands. But weirdly some Teams calls or streaming continuing to work, even on the same device. Been happening for about a month. Also been noticing a lot of DoS attacks though i know lots of these are false positives. Really no longer enjoying the netgear experience. Is there anyway to add weight to this to get NG to take a look. Link to comment Share on other sites More sharing options...
JustWantIT2Work Posted February 24 Share Posted February 24 Ive always noted weird things with the DHCP on the router. Some of my wired connections flick from online to offline in the network view (which is the worst part of the OS for me). But also had the same device seemingly allocated multiple IP addrrsses. I had the 1.1.0.22_2.1.34 firmware for a little while but had an email from netgear thia weekend saying a new firmware is available. I note the webpage says its updated this weekend but the firmware is still 1.1.0.22 so is it really an update? Oh and the netgear website returns an XML error and not the firmware!

Administrators Netduma Fraser Posted February 24 Administrators Share Posted February 24 The update is just for security updates so you're not missing anything/it's unlikely to fix or have caused the issues experienced. It's a long running issue that does seem to be caused by DHCP renewing. NG suspected it was an issue caused by a Nintendo Wii I think, which I am not sure how they came to that conclusion as I don't think that was being used on any of the routers we provided information for but if any of you have a Nintendo Wii or more likely a Nintendo switch try disconnecting it and see if you get the same issues.

Rx39141 Posted February 24 Author Share Posted February 24 Probably my last update on this thread. Router seems to be bricked now. Woke up and no internet connection on any devices. Did a hard reset with the physical button, but still no internet on any devices. Took my modem out of bridge mode and setup its router. Internet starts working again. I don’t think it’s worth sinking any more time into troubleshooting further. A sad day! I really liked this router. Thanks for the help Netduma Fraser.
