I am looking to add a mesh to my existing home network. I have ATT as the ISP and they provide a combination modem/router. Is there a concept of a primary mesh host? And will that plug into (using the Ethernet cable) my AT&T provided router/modem combo? Or do I need to replace the existing router? And if it does plug into the existing router, will the mesh SSID be the same as the existing router?

 

I am looking to provide a level of indirection for my home network with the SSID such that I don't need to change all the connecting home devices when/if I ever change the ISP. Almost unbeknownst to me we have accumulated ~14 devices connected to the home WIFI and it is a royal pain to go about changing all of them when the ISP changes. I believe having a mesh will provide this (in addition to the blanket WIFI within the house).

 

Thanks much for your help!

Yes, You can disable the ISP WiFi, connect your Primary Deco node to the ISP's Router and connect everything to the Deco WiFi.

@DAServices - Thank you very much, this modem/router is a single unit. And when you say, "disable" the router, are you suggesting using the modem/router admin console?

 

Would it work if I were to leave the ATT router enabled but give the Mesh the same SSID as the existing WIFI? Thanks again

@nrgs 

Best practices suggest that you disable the WiFI on the ISPs modem.  If not then using the Deco in Router mode as well as the AT&T router, could lead to double NATing and that will cause you a myriad of headaches. 

 

Take a look at the attached PDF. I have documented my steps for the ARRIS BWG210-700.
