RBK752 RBR750 Crashes During High Speed Downloads Over Ethernet

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

I don't have a modem. With Google Fiber Webpass the modem is essentially the satellite on top of my building, and an ethernet cable runs from it directly to my unit where it connects with the Orbi router. It's worth noting that I've been in contact with Google regarding the problem and they've done everything on their end to verify it is not a problem with their equipment. They've done a reboot on the modem/satellite to be sure, and no one else in my building is having this problem.

Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended. 

Yes all cables are CAT6 or higher and I've tried different cables too.

What downloads are you doing? Games? 

Mostly games but also some photo/video files for work. This problem happens regardless of what content I'm downloading or what server I'm connected to. Basically if the files are being sent in excess 800mbps from any source, the problem happens.

Can you post screen captures of these speeds seen? 

Not at the moment but I will soon. Netgear support has asked me to do the same and I will get to it by this weekend hopefully.

This has been a odd issue for user as others mentioned it as well on the 8 series Orbi. I have both and have tried it on my 8 series and downloading games on Steam as most users complain about this when downloading games from Steam. I've tried this a few times and have not been able to reproduce, even having two wired PC connected in back and downloading at the same time. I believe possible that I was not fully saturating the downloads or the Steam app was limiting the downloads so that the downloads were not being fully maxed out. No idea what that app does behind the scenes. 

I think our problems are different, since I can replicate the problem when downloading outside of Steam, and also I can replicate it on other PCs downloading at high speeds via ethernet connected to the same Orbi.

If your seeing speeds over 900Mbps on the down then possible the router is hitting it's max limit as the WAN and LAN ports are only rated for 1000Mpbs and which at most you should seen around 900Mpbs on wired speed tests and nothing more then that. For constant data downloads at this rate, possible that the HW could be getting hot or over limit and the router is hanging or stopping. Something NG will need to look into. 

I've thought it's possible I'm hitting some sort of limit, but that shouldn't result in the router crashing and needing to be reset by unplugging it. If anything, it should hit whatever the cap is and stay pegged there. In speed tests I typically get in the high 800s to mid 900s for down and upload speeds. I've hit as high as 1.2Gbps with this router, my old Orbi RBR50, and an old Linksys DIR 890 L. I agree it may have something to do with hardware getting hot over time from prolonged high speed downloads since the crash typically happens after at least a minute or so of downloading. But there have been a few occasions where the router crashed almost immediately after starting the download.
