Dropping Wired Connection (XR500)

As some other users have experienced, I've been losing connection a lot after upgrading to the most recent firmware V2.3.2.56.

This message seems to be the one to look out for:

[DumaOS] Error parsing line in ARP table: '[redacted] dev br0 lladdr [redacted] STALE', Thursday, February 27, 2020 12:39:44


More tagged spoiler (from a fresh boot of the router)

  Reveal hidden contents

My internet browsing is slow and unreliable. Games are unplayable for short periods where everything fails.

Where can I download the previous firmware version? Everything ran smoothly on that.

Is there anything else I can look out for this this?

I will update the post with more information after eating dinner :)

Thank you in advance!

EDIT - Additional Information

I often have trouble accessing the router from my PC (192.168.1.1 - no internet connection message). This implies the problem is between the router and PC.

I'm connected via PPPoE. I'm using static IP for all devices (but tried dynamic for my main pc for a while to see if it fixed it - it didn't).

My QOS Anti-buffer is off.
I've disabled my Geo-Filter - made no difference
My main PC is prioritized for Bandwidth allocation - I see no way to disable this feature.
I have around six or so wireless devices and three wired connected.
I've rebooted the router a number of times to see if that would help - it didn't

I often get the message "You are no longer connected to your router. If your router is rebooting then keep this page open as it will automatically reconnect to the router's interface when the reboot is complete. Otherwise please check your connection e.g. you are connected to the correct router." when interacting with DumaOS.
I'm using the router as a DHCP server (think that is default)

I've added a little more data from the last ten minutes after starting my pc below:

All the [redacted] comments were put over addresses. If those are relevant, please let me know.

The addresses appear to be in the IP6 format. My computer is currently set to IP4. Could that be related? Should I enable IP6 for my PC and on the router?

If there is any other information that would help, please let me know.

Have you tried to reinstall .56 then rest afterwards and setup from new not using a saved config? Use the pin hole at the rear to reset.

 

https://kb.netgear.com/000060464/XR500-Firmware-Version-2-3-2-40

 

please note that the latest .56 includes security updates so by rolling back it’s not fully covered with the latest security.

To be rolling back this late after an update in August ish 2019 with no fix from either company is sad. .56 covers you anything goes wrong before and Netgear will say its up to you to keep your router updated if you get hit by the Ntegear DoS vulnerability and your router gets in any way messed up, let alone your LAN. Kinda sad that the router is sitting in this state still with Netgear doing nothing to fix things and Netduma hoping 3.0 will fix all issues but with no patches since December 2018 from them and that was milestone 1.3. I really hope 3.0 and Netgear updates fixes the nighthawk XR range once and for all (with patches to follow of course) ;)

Hey, welcome to the forum!

Sorry to hear you're having these issues. What speeds do you pay for and what are you getting on average that makes browsing slow? What is your exact physical setup? You say you're using PPPoE - do you have this set to 'Always Connect'? If doesn't look like you are using IPv6 so I would disable this on the router if it is enabled. If you disable QoS via the Anti-Bufferbloat 3 line option menu then it will disable all features on that page. Do you access the router using routerlogin.net or the LAN IP address? If the former access via the LAN IP, can you access then? The previous firmware has been linked above but would be better if we could resolve it on the latest firmware due to security as KH mentioned.

Hi! Thank you for the replies.

I'm on a gigabit connection and get around 370 Mbps down and around 200 up.

I'm set to always connect.

IPv6 is disabled on the router and  on the network settings form the pc at the moment.

How do I disable QoS via the command line?

I access the router from the ip address - I've never used routerlogin.net.

As you say, I'd like to keep on the same version if it runs smoothly. Please let me know if there's anything else that would help.

Thank you for the link to the previous version. I will drop back to that if we can't solve this.

It tends to come and go. So it's not constant (it seems).

I've been getting a lot of lease change notifications as well.

EDIT

My PC network settings:

My IPv4 Subnet Prefix Length is set to 24
Gateway is my router address as is the DNS server.

I assume those look correct for a fixed IP address (the address is the same on the pc and on the router). As I mentioned earlier, putting it on auto didn't fix the problem.

Log of me giving up trying to play a game due to disconnects only to have tons of problems trying to watch Netflix:

EDIT

Just checked when I bought this - April 2018 (for $400 - expensive in Japan).

I really don't want to have to return this...

Just to give more information (for the benefit of support and others), that's not a typical hour. The connection problems come and go.

It resets the router back to factory settings and clears low level stuff. If you just reset and still have issues try reinstalling .56 over the top followed by a reset. I bet that solves your issue.

Could  not agree more if all else fails, logout factory reset via pin hole wait 5 minutes set up and don't use a use a backup and that may reintroduce issues from the previous set up. Solves all issues unless its hardware mostly...

I agree with Killhippie and Newfie.. Your best chance for stability is resetting the router to factory with the little pinhole in the back of the router and setting up from scratch.. Once you reset it give it sometime after to fully bootup and then proceed to configure it from scratch.. Also clear your browser cache and cookies.. Hopefully then things should be stable for you again.. Post back with your results. Good luck!

If it’s kinda working it means it’s not and while you will have access to the internet the chances are something or multiple somethings are not working as they should. Think of it like a Scoda that is stuck doing 30 mph where it should be doing 80mph.

Totally right although some routers like Scoda's are somewhat limited due to build issues for the vehicles engine management... If its kinda working it isn't working at all really and really  needs to be reset. if you login via a pc or mac just take screenshots of the settings so you can copy them back. Best to avoid a config file of a buggy install as it may bring low level code issues with it to your factory reset clean install. Also reloading the firmware again can really help before a factory reset. Good luck getting that Scoda up to 50 Mph ;)

I can understand why one would not want to touch things if there working..Or seemed to be working.. But its like a double edge sword. Damn if you do damn if you don't. My XR500 is very tempered.. It doesn't take much for it to get shaky in the knees.. Ive learned a lot though what triggers certain things to happen over time..  And how I can make some things better.. But it is a lot of trial and error. Ive still to this day have been trying to figure out why the minute I enable QoS/ Anti Buffer Bloat why my speeds disappear by even moving the sliders one percent. And when I mean one percent I mean setting them at 99% I should lose roughly 1-2 Mbps.. But I lose 50 Mbps right off the top! From there things unravel and my only course of action is a factory reset. And not to even touch the sliders.   Ive looked at the Ops log files and I could easily spot an issue when looking at them. My only advice to the Op is watch for any logs that state the word "STALE". That is a clear sign a factory reset is needed. Anytime one sees STALE along with other info that means that particular process and or feature is no longer working and has become unresponsive. And the only thing that usually clears it up is a factory reset..

Op I hope things are working now for yah!  👍

Whats up Zippy speaking of that stale word I was browsing through my logs after I read your post! You recommend that I do a factory reset then? This is why I read through these forums you folks teach me a lot of stuff I have no idea about! Btw the game was playing extra bad last night so idk if this has anything to do with it.

If your seeing the word "STALE" attached to a log entry then yes that means something is unresponsive or no longer functioning. How I came across this is by reaching out to an individual from Netgear.  Awhile back I had asked about my IPV6 problem of why it works for awhile then quits. Turns out it works for a bit then goes STALE. And this means the function or program is no longer working or responding. And that also goes for other functions/programs or what have you taking place in the router. If you look at the Ops log you will see something like "Error in parsing line in ARP table" with some other info and the word STALE. All in the same line means that function or process is no longer working or responsive. Sometimes this may correct itself but its best at that point to do a factory reset..

Just to be clear this has nothing to do with IPV6. That was just an example I used here. My XR500 for some reason drops my IPV6 connection. Its an XR500 issue. 

My advice is if you see the word STALE along with other info in your logs I would just do a factory reset. He mentioned it is the best course of action. 

Hope this helps you! If you remember see what it was that went STALE in your logs.. Post back here if you can and or need additional help! 

Good luck my friend! 👍

Thank you all for your replies. I do plan on doing this, but it seems to be working for now and I don't have the energy after work to deal with this quite yet. Thank you again (I will update with the results).

Excellent glad to hear things seem better! 👍 Just keep an eye on it and every so often check your logs for key words like "STALE". You should be okay now though. If not you know where to find me! ;) 

Cheers man!

So with all the news of the latest Netgear vulnerabilities, I am not going to do a rollback.

Expand  

Looking at this article of this issues: https://threatpost.com/critical-netgear-bug-impacts-nighthawk-router/153445/ they're just reporting essentially on what has already been patched such as this one: https://kb.netgear.com/000061760/Security-Advisory-for-Post-Authentication-Command-Injection-on-Some-Routers-and-Gateways-PSV-2018-0352 so if this is one you're worried about specifically then dropping to .40 would be okay. .56 does have some other security fixes so totally understand if you don't want to downgrade. Hopefully it continues to work how it is at the moment.

Yo, I got that error in parsing line again. I just factory reset the other day. Why do I keep getting this in my logs? I shouldn't have to factory reset all of time like this

Hummm I would have hoped this would have lasted longer for you.. That error your getting is that the one in the ARP table?

Thanks!
