You purchased the incorrect MESH system; the R15 is a dual-band model. It would have been wiser to invest in a tri-band MESH system for better performance. Simply acquiring more MESH routers will not address the issue.

You now have two alternatives:

1. Connect all R15 units using Ethernet cables.
2. Discard the existing R15 routers and upgrade to a tri-band MESH system.

In a dual-band MESH system, the 5GHz band is utilized for both inter-router communication and connecting with mobile devices.
Conversely, a tri-band MESH system features an additional 5GHz band exclusively reserved for inter-router communication, enhancing overall performance.

The cheapest would be TP-Link Deco X75

Cheaper if you're willing to downgrade to Wi-Fi 5 (Wi-Fi AC)

What do you mean by "Single Device"?

Single laptop or single MESH router?

No effect
Tri-band single router will only help if you have lots of devices at home
