Xfinity Pods Going Offline

I have an Xfinity gigabit connection - and 6 pods spread throughout my house. Like many people have said in this Community Forum, I frequently have the pods go offline.  Sometimes the pods will come back after a while without any intervention. Other times it takes unplugging and replugging the pods in - and waiting.  Sometimes I need to restart the gateway.  

I never had this issue with other mesh networks from wither Google or Amazon.  I purchased the pods to have the best alignment with my Xfinity system, and I'm shocked at the bugginess of Xfinity's hardware and software.  It is amazing that Xfinity gets away with releasing such substandard products.  (I used a different word than "substandard" but the Xfinity AI told me I had to change it).

Any advice?
