Changing modems with Google WiFi

[joegaeta71]

So, here is my situation.

I live in a large, 100 year old house with thick walls and many "dead zones".  I have had AT&T Fiber with the modem/WiFi-router combo that that came with it for a few years now.  After several initial attempts at using its built-in WiFi and using many different "extenders" to no avail (could never get signal in the opposite side of the house), I invested in Google WiFi and have been very satisfied!  Works well. A great product.

My set up is a bit unusual, I believe.  I utilize the "WiFi Gateway" that comes with AT&T Fiber as my modem.  It is a combo modem, wired router, and WiFi router.  I have two AppleTVs and a desktop computer directly wired into the router via ethernet.  I also have my Google Wifi's primary WiFi router connected via Ethernet. My Google WiFi network builds off of that connection. (There is not WiFi interference b/c the primary Google WiFi router is across the house (a long ethernet cable run through the basement).

Now.....on my GoogleWiFi networks, I have a SEVERAL smart plugs on the wireless network and a Sonos multI-room speaker system connected directly to the primary Google WiFi router via Ethernet.

Indeed, it's a bit convoluted; but, it has worked seamlessly for a few years.

Now, for my question:  If I upgrade or change my internet service and get a new WifFi Gateway from AT&T (I'm thinking about upgrading from their 1gig to their 2gig service).......can I just plug my GoogleWiFi primary router into the new modem straight away, or will have to reset my GoogleWiFi from scratch (and, by extension, having to re-configure all my smart-plugs and Sonos system)?  i.e.....is it as simple as unplugging the Google Wif's ethernet connection form the old modem and plugging it back into the new one - or do I have set everything up again from scratch?  Will it remember my GoogleWiFi wireless network?

Thanks!

I dont think that the ISP's modem/router 'remembers' you Google WiFi. As I understand it the modem/router treats the Google WiFi primary as a simple wired Ethernet device - it doesn't know that it is a WiFi device.

So no reconfiguration of the Google WiFi mesh necessary. But switching to a new modem/router is simpler if the new modem/router has a DCHP service and is allowed to dynamically allocate an IP address to the Google WiFi primary.

Hi, everyone.
Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.

Hi, everyone.
As we haven't had any activity here recently I'm going to go ahead and close the thread. If you have more to add, feel free to start a new discussion.
