This is the exact same issue I’ve reported a few times on this forum and I have an open ticket with NG (5+ months now with no resolution). I’d suggest reporting a ticket but don’t get your expectations up - I’ve not had a response on my ticket for over a month now and have provided a ridiculous amount of information, logs etc.
The system does “something” precisely every hour, I’ve tested this extensively. The time it occurs might change (if say you reboot or hw crashes which seems to be another issue right now), but it’s guaranteed like clockwork.
This seems to affect devices connected to the satellite only and not the main router (at least for me). I’ve also changed ISPs (and from DOCSIS 3.1 to full symmetric 2.5gb FTTP) and the issue persists. So this 100% is not an ISP/external internet connection issue, it’s a process or something happening on the mesh system and NG need to fix this. It also occurs when using only internal traffic and no internet.
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.
Something to try as well, put a non managed Gb LAN switch in between the ISP modem/ONT and the RBR and see if this problem continues.
Does this interruption occur if you disable IPv6, All Logging on the RBR and Armor, Smart Parental Controls or Circle, Traffic Meter.
If your ISP supports IPv6, which protocol are you using on the RBR?
Are you using ISP IPv6 DNS or custom IPv6 DNS?
Also try putting a cooling fan on top of the RBR unit.
Can you check the RBR web page under advanced tab/Internet section/Show Stats and look at the WAN port Uptime and then check the RBR debug.htm web page for system Uptime to see if these values are the same?
Also please give the CPU usage value as well.
Has a factory reset and setup from scratch been performed since last FW update?
I've not found any solution as of yet - doing a full reset will not fix the issue (I've done that multiple times). This has been present on all fw versions and the beta versions they've given me. I've provided logs after logs and gone through so many steps. There is clearly some process or sync event that's happening that causes this.
As you've highlighted - it's a short spike of 500-1000ms for a second or two and then it's back to normal.
I've had older orbi mesh systems oevr the years and none of them have ever exhibited this. Please raise a support ticket with Netgear to highlight this issue as I feel they are just assuming it's some random set up issue I have, but it's evidently not.
My case number if you want to reference is 48580405.
