Just an update.

 

It's still happening on occasion but today I noticed that my desktop had no connection (wired) whilst my roommates desktop (also wired) was working fine.

Thanks for the update Achilles, I have heard back from the Netgear team. They've been unable to reproduce it (unsurprising as it is seemingly random). They've asked for a user to provide TeamViewer access once the issue has occurred so they can debug it. Would you be willing to help with this? 

 

Basically when the issue occurs just have TeamViewer running on a wireless PC that can access the interface & confirm that wired devices have no connection to the router. I think you're in the UK is that correct? In which case you'd have to leave it overnight for them to debug.

I am experiencing the same issue and have only owned this router for 1 day now. It has the latest firmware loaded. What I see in the logs proceeding the wired connections dropping was DHCP was handing out new leases to those connections not that this is a cause but maybe an introduced bug to the latest patch. I rebooted both my modem and then the router and connections were restored.
Below is the only error message i have in the entire log and was in the same time frame that it dropped connections.

Thank you both for letting me know you're experiencing this as well. I'm talking directly with Netgear and hoping to get Achilles to provide TeamViewer when the issue occurs so they can debug directly. 

 

Fix at the moment is reboot/factory reset. We're working hard to make sure this gets resolved as quickly as possible.

Also can you try disabling Auto QOS - so have it on Always or Never and see if that resolves the issue please.

Based on your pattern it seems that Arris sb8200 dropped connection, in that case just reboot Arris, I used DHCP lease release/renew event on XR500 to monitor Airris disconnects, in your pattern you would loose wifi as well. Please create the case with Arris and internet provider.

Thank you for the reply. If this was the issue with the arris then my iPad and other devices would have been offline also but they were up and connected to the internet. What made me think it was software related was the fact I was connected to the router and was configuring my geofilter when I went offline and I remember exactly what I was doing I selected strict mode in the geofilter then offline I went. I had a pc, iPad,Xbox and laptop online during this event and everything that was hardwired went offline. I did in fact check the arris logs and so no disconnects but who knows I will keep an eye on it since I am still getting use to this router and will provide more feedback if I find anything.

Please try my suggestion here ^

 

I'm getting more information for Netgear developers as well.

I see you still have WIFI, in this situation one of the triggers I had with Arris sb8200->XR500 is when you would got to setup of XR500 and try to go via setup wizard and complete setup, within 1 hour Ethernet ports will disconnect. but once I reboot XR500 Ethernet ports will stay up for awhile. In my case Arris sb8200 needs to be rebooted daily with 1gbps service and once in a few days when I downgraded to 150mps.

My current setup is Negear CM1000->XR500, and no matter what I tried last 2 days setup is very stable, I tried stress test as well, nothing could bring XR500 down.

My qos was set to always. I will try your suggestions to see if I see anything different. In my case this has only happened 1 time in 24 hours and will review and post anything new.

Great info thanks for pointing me in the right direction. My arris is overkill since I only have 280 down and 12 up. I just bought it because I trust the Broadcom chipset but may go back to Motorola still Broadcom chipset if this is the cause of my issues. I just had a Asus 3100 and linksys wrt 3200 they both did not have any disconnects. I did own the dreadful puma chipset been through that.

Is this a normal thing happening in the logs?  Maybe false positives.

Yes those are all fine. Logs are mostly for the developers so they're quite verbose.

My QoS was set to "When High Priority Traffic Detected" but I've set it to Never to see if that helps. 

 

Traffic Prioritization was also enabled.

 

I'm currently in the US and have my laptop so I could technically get them access with Teamviewer. Only issue is that this often happens at night and so with roommates etc who need access I'm often quickly resetting it to not cause any problems. 

 

Other than that I'm happy to help.

 

I want to say it has been happening less than before and I haven't really changed anything network wise but it's definitely still an occurrence..
