RBR 750 intermittently crashes with high load on ethernet

What Firmware version is currently loaded?
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. CAT6 is recommended.
Are the RBS ethernet connected to the back of the RBR or is there a LAN switch in between?
Having 2.5Gb ethernet adapter may not be recommended as the 7 series system doesn't support 2.5Gb connections. Try setting these adapters to 1Gb max connection rate if you can on these adapters.
Try using 1Gb ethernet supporting adapters.

I've got an RBR750 (latest firmware, +2 wired satellites) connected to a CM1100 cable modem with gigabit internet via Spectrum. Everything mostly works well, but I've noticed intermittent crashes when using my desktop computer connected via ethernet.
This seems to happen with high-bandwidth activities such as running Speedtest.net or downloading via Creative Cloud. It's doesn't happen all the time, but when it does happen its been during one of these activities.
I've tried 4 different NICs.
1. No name brand Realtek 2.5g - same problem
2. Technet Realtek 2.5g - same problem
3. USB Realtek 2.5g - does not have this problem
4. Motherboard (ASUS x570 Prime Pro) Intel i221 - I don't think it had this problem, but I ditched this NIC because it was dropping the internet connection repeatedly for a split second (which is the reason why I changed NICs). Though thinking back I wonder if connection losses I've had in the past were the same issue.
So using a USB Realtek NIC seems fine? I can't for the life of me figure out what's going on. I guess I can keep using the USB NIC, but I'd like to get to the bottom of this.
This is totally a first-world problem but I'm on the verge of ditching the Orbi or buying a separate router and just using the Orbi as an AP.
I'm on the latest 4.6.9.11 firmware. I'm using a Netgear CM1100 cable modem. I have a switch between the router and the satellites - but my computer is connected directly to the router.
Thanks for the advice, I will try Cat6 cable and setting the adapter speed to 1gig rather than auto. Will report back!
Meanwhile I am shopping for a dedicated router like the Mikrotik RB5009, but unfortunately (or maybe fortunate for my wallet) they're impossible to find right now.
What is the brand and model# of this swtich between the RBR and the RBS?
Does the RBR still stop working under high load if you turn OFF the switch and the RBS with your wired PC connected to the RBR?
Please configure the 2.5Gb adapter do that it forces a 1Gb connection on the adapter, not auto detect speed.
What are you doing go cause this high load? Streaming or downloading games?
The switch I'm using is a Netgear GS316. I've had it for a few years and it has always run perfectly as far as i can tell.
I haven't tried turning off the switch (pretty much my whole house is wired through it, except for my desktop PC), but I'll give it a go.
I've tried setting the adapter to 1gb without any change.
I've seen the internet connection loss under two scenarios.
1) When running speedtest.net. The connection drops just as the download speed is ramping up. The only way to get the router up and running again is to unplug and replug the RBR750.
2) When updating via Adobe Creative Cloud
Again I know it's a total first world problem. I guess "just don't run speedtest" is one solution, but it is annoying to not being able to figure this out/stop it.
Devices announcing that they have no internet is an ambiguous situation. Sometimes this indicates that they are unable to resolve URL's into IP addresses. In the case of the Orbi router, I have a suspicion that it indicates that the router was unable to connect to a specific Netgear URL.
Can you please humor me and the next time you replicate this condition, can you test whether ICMP (ping) works but DNS resolution does not? i.e.
- Open a Command Window and type ping ford.com.
- If that fails, type ping 19.12.113.37
If this experiment is successful, try replacing the DNS entries in the Windows Ethernet adapter settings for IPv4 to use different DNS servers than the Orbi router, such as 1.1.1.1 or 8.8.8.8
Is it possible to replicate this situation with any other device on the network? (Another PC or laptop?)
