contour box keeps resetting
i have the main box and the extra smaller box. for 2 weeks now the box keeps getting a pop up message saying the check the connections and the then the box wants to restart. We have has 3 different cox techs out to look at it, changed the boxes twice. tapped into different feed lines. They say the signal is strong but it seems to keep getting worse and worse with the resets. On tech said that a new cell phone tower could be causing interference i the lines. They said that the wireless boxes may be better but i can only have 2 at mu house. One tech said maybe up to 4, another said 3 but the store says 2. I am an confused about what the issue is and what can be done to fix it.
