I have had That exact same thing happen at the office. What I did was pull up comcast speed test and do a test at the time of the internet issue. (If it lets you get that far) Give them your findings when you call. They eventually found that the junction box outside had gone bad. But Mine did the same thing. Perfectly fine and then it would just die. Of course, it didn't want to do it when I was on the phone with them!!
