Internet goes down every day around same times

For the past month, I've been seeing my internet go down once a day between the times of 330-630. It always happens almost to the minute at :30 but the hours can change daily. The service and speed is 100% normal, and its like my modem has been reset from the source or something. I've contacted cox and all they asked me to do was reset modem (which I've done) and rest my internet connection which I've done multiple times. Why does my connection drop once a day, and almost like clockwork? Its really starting to get annoying.
