Hello @JuneLJ ,

Thanks for contacting our community.

I'd like to know which of the following situations you are referring to when referring to port 1 and port 2?
If it is the second situation, please note that the combo port pairs an RJ45 port with an SFP+ port. Only one port in the pair can be used at a time.

Also, please check whether your PC supports 10Gbps negotiation and the specifications of your Ethernet cable.

Hi @JuneLJ ,

Thanks for getting back to me.

Please confirm that you have set Port 1 as the WAN port in the Internet page:

Is there a switch between the BE800 and wired clients? What are the models of the switch and clients?

Do the Ethernet cables, switch, and clients support 10G?

Hello@JuneLJ,

We would like to escalate your case to the support engineers, and they will follow up on it. If you are willing to conduct further analysis, please check your inbox and respond.
