I have the rbr750 orbi system with 2 satellites. The current firmware is 4.6.8.2_2.1.9. My download speed is supposed to be 1000mbps, but speedtests around 600-900 at normal times. But, everyday, this falls to about 10% (60-95mbps), until I reboot it, and then it's back to its normal range. It stays there for most of the day (and sometimes 2 days) till it requires a reboot again.
Any idea what's going on? Speeds are measured through the orbi app.
Results are the same using speed test. I notice the speeds drop on hardwired devices and that's when I test the speed and see the bad results. Reboot generally fixes it, but recently I've had to hard power recycle the router to get the speeds to restore ☹️
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. If your ISP Modem or ONT supports 2.5Gb on there WAN port, CAT6A STP cable would be recommended.
I don't have a cable modem. It's directly connected to the line outside my house. The outside line is connected with Cat7 which feeds into the Orbi Router. I will ask the cable company to redo the pinout on the external connection to see maybe that fixes the problem 🤷🏽♂️ I'm really out of ideas
Thanks for providing the screen shot of the Show Statistics page. The Orbi router has determined that the WAN link to the ISP device has a maximum capability of 100MB/s. At that point, that is the theoretical maximum throughput. In actual practice, a little over 90MB/s is possible. The mystery, then, is what has caused the Orbi to determine that a link that was once capable of 1000MB/s is suddenly only capable of 100MB/s, but then returns to 1000MB/s when the router is rebooted.
Auto-negotiation is the technology used for the ISP and the user router to determine which speeds are capable:
It is built into the Ethernet hardware chips in the router and the ISP device, and is supposed to be "automatic".
There is a way to determine whether the fault lies with the owner router or with the ISP Ethernet cable + media device:
Disconnect the router and connect a computer with Ethernet connector and see if this continues to happen.
Since it may take two days for the problem to manifest, this is obviously impractical. (pick a description: unacceptable, ridiculous, impossible, the family will kill me, etc.)
I think the way forward is to contact the ISP. Intermittent problems are very difficult to resolve.
Thank you @CrimpOn. The WAN speed was the first thing I noticed as well. I have an ISP technician coming tomorrow and I hope to explain this to him, but I'm not sure how much they will be able to help. I have had mixed results with the quality of techs that show up.

Enjoy the humor. ('mixed results'). To me, the key is that the speed changes without touching anything. No wiggling connectors or wires. No unplugging or replugging. The obvious first step is, "well, change the cable." But, why? I can see a loose cable connection causing a problem (maybe). But if the cable is not touched at all and the problem goes away.... then???
So it turns out, the tech was actually really smart. Since my house is wired for Cat7, when the internet was started back in the day, that tech didn't have a way to pin a cat7 cable, so he had fenagled a cat7 to cat5 connection which was shady at best. This was behind a "locked" section which I couldn't see, so I had no idea it was so badly done. This new tech, ripped it all out and wired it correctly. It's still a cat7 to Cat5 connection, which adds a point of failure. These guys don't carry cat7 pins or crimper tool. I've ordered those so I can just make that connection directly into the ONT outside instead of having that connection. But for now, it all works and speeds are back up.
