Printer Not seeing my wifi after I forgot the device

Hello, 

We have the Panoramic wifi and I use the Cox Wfi app. We have been having issues and I went in to rename and assign all of our stuff. I paused the printer and then when I us paused it it will not reconnect. So we reset everything and I even forgot the device. Not the printer can not see the wifi to connect to..... It is for frustrating it has been on this network for 3 plus years! Why can it not see the Wifi anymore? It can see other networks outside of our home and it will connect to my phone hotspot. 

Please help I am pulling out my hair!
