Thanks for the info! Would the moca 2.5 at least increase my speed for PC's or Xbox's?
Possibly. It depends on how you currently have them networked.
If they're networked to the router via Gigabit Ethernet, no; a MoCA 2.5 path* would surely be an improvement over wireless or standard MoCA 2.0, though.
* meaning... upgrading to a MoCA 2.5 adapter as your main MoCA/Ethernet bridge, and add'l MoCA 2.5 adapters wherever you're looking for the improved bandwidrh.
What is your current Internet download/upload rate for which you're paying?
