Intermittent wired connection from RBR750 router to my laptop. What's up?
I am hardwired to my Orbi (RBR750) router and get intermittent internet connection. It's hard to tell if the same problem occurs on the wifi. I think so.
I've rebooted the modem and router multiple times. I've done tests with the ISP (Spectrum). No luck.
When it works, the speed tests say 300+ Mbps down and 11 Mbps up. That would be good for our location. When it doesn't work, cached pages don't open until the 2n'd or 3rd try. Mid-use, pages freeze, then come back to life.

Do any other devices on the network exhibit the same behavior?
Does this happen "right in the middle" of using the laptop, or does it happen after waking the laptop, such as opening the cover or waking it from sleep mode?
Re: Intermittent wired connection from RBR750 router to my laptop. What's up?
My situation is different (old RBR50 router. Windows 10 laptop.) The question was because of an annoying feature of my Lenovo laptop over a year ago (maybe two years?) Wired directly to a router LAN port, when I would open the cover to wake the laptop, the network icon in the bottom right would remain a globe (or whatever that symbol is) indicating "no internet". Running the Windows Trouble Shooter would fix it. Changing to WiFi and then back to wired would fix it. Disabling the enabling the wired adapter would fix it.
Finally I captured the actual Ethernet packets between the laptop and the router. There was a clear pattern:
When the lid was opened, the laptop would wake up and send a correct DHCP request.
The router would respond with a correct DHCP assignment.
The lapto would send the same DHCP request again.
The router would respond with the same correct DHCP assignment.
And this pattern would go on, and on, and on, and on.
Then, one day there was a software update on the laptop, and the problem simply disappeared. So, if specific actions trigger this situation, there might be an issue with the laptop.
On the other hand, there was a post (just yesterday?) about a similar issue where the ISP replaced the cable drop and a similar problem disappeared. (and now I cannot find that post. sorry)
