I have an Arris SB8200 modem that has worked well for several years, with no issues. There were some early on, but those were resolved with line repairs by Xfinity. A while back, Xfinity gave me an automatic upgrade to 1200 Mb per second, but I kept my gigabit modem since I was happy with the lower speed. Recently I have had intermittent dropouts on streaming music and video services and the modem reception light that had been blue(Docsys 3.1) is primarily green, with occasional brief attempts to change to blue. Initially xfinity service suggested it was due to upcoming line service in the area. That time has passed, and nothing has changed, so today they told me the problem was incompatibility between their upgraded equipment and my modem. They suggested I rent equipment from Comcast and that would solve the problems. Does anyone have any suggestions or experience with this kind of issue? Should I have a technician come out and check the lines on my end to determine what else might be going on? If they conclude, the problem is the router, I will be charged for the service call.
