New Wifi Modem/Router Problems

I recently bought a new Nighthawk router.  I have an Arc on one tv and a Beam on another.

Both speakers are still working great.

When I open the Sonos App, neither shows up.

From what I can tell, I need to change the WIFI info stored on the Arc & Beam to the new Nighthawk.

I can’t seem to make that happen using the app itself, but have read that if I plug the Arc into the Nighthawk with an ethernet cable, it will transfer the new Wifi info to the Arc, which in turn will update the Beam.

I will then be able to see them in the app.

Sound right?

I don’t want cause problems since they’re working fine at the moment.

Thanks in advance for your help.

Steve

If you end up needing Ethernet Amazon has 50 and 100 foot ones for good prices. The Basics ones are good enough, don't pay $200 for an audiophile Ethernet cwble,

Another easy scheme is to install the former WiFi SSID and password into the Nighthawk. At this point you will also need to update any devices that you’ve already changed to the current Nighthawk credentials.

Sorry for the delay as it took me a while to get to it. I was able to get both speakers on the new wifi using a cheap Amazon ethernet cable. Thanks very much for the help. Take care.... Steve
