Can I add older satellite to newer Orbi system?

[kirkmc]

I bought an RBK753 last week, replacing a nearly 6-year old RB50 system. With the former, I also have an additional satellite that I bought a couple of years ago. Can I add this to the RBK753 system? Will the slower speed slow down the entire network? And if I connect it via ethernet, rather than wifi, will the mitigate the slowdown, if any?

No, they are not compatible.

You can't add the RBS50 to the RBK753 wirelessly by I think you will be able to connect it by Ethernet.

If you will have AX features activated then devices that support AX will fall back to AC when roaming from RBR750/RBS750 to the RBS50.

Otherwise I think the RBS50 will work as a normal satellite in your Orbi mesh system.

They are not compatible wirelessly or ethernet.
