My mother recently upgraded her modem/router that is connected to the cable internet connection upstairs. The Beam is downstairs. I noticed the signal was weak downstairs so I bought a Netgear AC1900 Wifi Mesh Extender and installed it on the main level. Since its a mesh extender it sets the SSID to the same as the primary wifi router. After doing this I was able to test a good signal in the basement and able to add the samsung smart TV in the basement to the wifi and stream video with no issues. I then tried to follow instructions to change the wifi network on the Beam that is the sound bar for the samsung smart TV in the basement and the SSID does not show in the available networks to select to in the sonos app. It says make sure your network is b/g/n compatiable. I’ve verified that the Primary wifi router and the mesh extender are both backwards compatible. So now I’m at a loss.
