Orbi RBR-752 ethernet port issue

[vics-orbi]

I have a Orbi-752 which is about 3 months old. I have been noticing that the ethernet ports keep on dropping the connection intermittently, specially when I do speed tests. I have CenturyLink 940Mbs fiber connection and I am using the Orbi directly, meaning not using CenturyLink's router.

Any suggestions ?

Thanks

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

Does the front LED turn at anytime whent this happens?

Do all LAN ports in back experience this? 

Does wireless still work? 

What kind of LAN cabling are you using? CAT6 is recommended. 

Be sure to check for bad cabling as well. Swap LAN cabling to test.

It seems that it was cable issue. Thanks

Good to hear. 
Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
