Mesh whole home wifi

Since getting the mesh wifi deco s4 I cannot get live video or recorded incidents. There is also a slight delay. I am very unhappy. When I call in they keep me reprogramming even though o tell them this is not going to work for hours. I have spent several hours on the phone with people who have no idea how to fix. I ask them to accelerate the call they all but refuse. Yesterday I was told a supervisor would call me back after an hour of my asking and guess what? No one called back. I have the deco set at 2.4 and have read many articles. This is my last request for help? Very frustrated and disappointed in ring
