My wifi extenders stopped working randomly. They use to work fine, the lights were on, these are the ceiling units (r150). I called Ring, who took over for amazon, they told me I needed to troubleshoot with the switch icx7150. I sent them an image of my wifi cable closet and there was apparently no icx7150 in there. I have no idea where lennar or Amazon may have installed it. I have no idea what to look for or what questions to ask. my home was a brand new bought at the very end of 2019, I'm so frustrated. please help me
