Hi @Kaenath 

Welcome to the community!

Glad to hear everything is running fairly well with the RE315s set up in AP Mode.

As for seamless mesh, the ER605 is an Omada wired router, so it doesn't support the same mesh technologies as the RE315s, which are non-Omada Range Extenders. The RE315s support OneMesh and EasyMesh options.

However, for OneMesh or EasyMesh to function, the router must also support either OneMesh or EasyMesh. In your case, unfortunately, the combination of ER605 and RE315s isn't really a suitable hardware combination for a Seamless Mesh Setup.

If you would like to stick with the ER605 as your main router, I'd suggest considering an Omada Mesh Setup using some of our Omada Access Points and an Omada Controller (required for Omada Mesh).

For example, a combination of the OC200 Omada Controller and at least a couple of EAPs from our Product List Here, in conjunction with your ER605, would provide ample business-level management while supporting seamless Mesh Wi-Fi.

If this sounds like a solution you may be interested in, check out our article here on how to build an Omada Mesh Network using the OC200 and various EAPs.

If seamless mesh is a priority, you can't go wrong with a Deco Mesh System. Additionally, your existing Ethernet Backhaul will help ensure optimal bandwidth and stability for each node. The Deco X20 should work great and vastly outperform the RE315s in every way.

Do you intend to continue using the ER605 as your primary router with the Deco in AP Mode? Or would you use the Deco as your main router, replacing the ER605?

If the former, just be aware that some Deco features are only usable when the Deco is in Router Mode. For more details, see our FAQ here on the differences between AP Mode and Router Mode for Decos.
