Internet outages

Why does Xfinity management marketing bombard customers with ads requesting for more wifi, when Xfinity doesn't seem to maintain what is already available. As a customer for many years, Xfinity Internet bandwidth has decreased so much requiring pods to have wifi connection inside the house. Xfinity Internet outages are occuring nearly every week for hours each time. It seems only a thunder shower will cause an outage. 

Very disappointed in Xfinity performance and customer service. Rural areas rely on internet as it is crucial in many homes.

wifi goes out every time it rains
