Re: Orbi speed issue
I have a similar issue. I have full 1GB fiber internet (up + down) from my ISP. When I initially reboot ORBI RBR850 and do hard wire speed tests (ookla) I see ~850Mbps download and ~860 Mbps upload...

My ISP claims the issue is between the ORBI router and their ONT Calix Gigapoint 803G fiber device. The Calix device has a small ARP table and clears it every 5 minutes. Per their diagnosis the ORBI device needs to send an ARP request every 5 minutes to stay in sync with the ONT. Netgear does not expose the ARP table timeout request setting so there is no way to do this. As a result the ONT ARP table doesn't know how to route traffic and results in the severely degraded upload speeds.
Sounds like complete hooey to me. The Calix has no IP address. It is just the equivalent of a modem which passes data between the ISP and the customer router.
On the older RBR50 product, the debug page has an option to record LAN/WAN traffic. (http://orbilogin.net/debug.htm ) I often record for while, save the zip file to my computer, and use Wireshark to look at the lan.pcap and wan.pcap files. If the Orbi is sending any ARP requests, they will show in the wan.pcap file. Setting a display filter to 'arp' (lower case) will get rid of the rest of the traffic. The Orbi will never ARP the IP address of the Calix because it doesn't know it's there. It should ARP for the MAC address of the Gateway IP it got from the ISP.
