ORBI RBKE963 randomly disconnects from Internet

Thanks for your reply.
I have the XB7-T gateway
Connected with a single Cat5 cable, no switch or anything.
Gonna switch the cable as soon as I hit send so we can check that off the list. Stranger things have happened...
I don't do anything to fix the disconnect. I learned over time that it comes back by itself in approximately five minutes.
Also, last weekend I factory reset Orbi to no avail.
I appreciate your ideas.
I will set the gateway back to router mode today. WiFi is not enabled of course.
Thanks a lot.

So CAT5 is only officially rated for 100Mbps. Lets try a CAT6A STP cable between the modem and RBR....

I used to have a ton of ethernet cables. I was in IT for 18 year before I retired five years ago.
I could only find two sad little cables with no markings on them at all so I just used it...
I just ordered the proper for sure cable from Amazon for delivery tomorrow.
The only way to be sure.
I just got lazy.
Thanks for pointing that out.
For what it's worth I have a 600MPS account with Comcast and the speed test this morning went to 702. I'm assuming it wouldn't do that with a real CAT5?
When I said "CAT5" cable earlier I really didn't know what it was.
I'm going to switch to that cable when it arrives and wait for it to fail before I reconfigure the gateway so I will know for sure which troubleshooting steps works rather than doing two or more at a time.
Thanks for your help.
I appreciate it!!

CAT5 is only supporting of 100Mpbs. CAT5e was good up to 1000mpbs. CAT6 is recommended for most 1Gb RJ45 ports on current LAN devices. With recent increase in connection rates 2.5 and 10Gb, CAT6A STP cables are recommended as the higher speeds can be effected by lesser CAT versions of cables. I ran in to a odd reboot issue with my 9 series connected to my CAX80 while using it's 2.5Gb WAN port. I had been using CAT6 UTP cables. After getting a CAT6A STP cable in, the 9 series returned to good normal operation. So I kind of keep in mine that 1000Mpbs ports CAT6 UTP should be good up to this point. 2.5Gb and higher ports, I recommend CAT6A STP cabling. It's supporting of up to 10Gb connection rated speeds.
