@DLabit29, It looks like the issue happened back on the 21st of October. Your modem is no longer reporting t3 errors at this time. Are you still experiencing issues with the service? -Allan, Cox Support Forums Moderator.
An intermittent issue is difficult to diagnose while there isn't an obvious sign of a signal level issue, but we can help reserve a return visit. Is the issue you're seeing happening at random or during a particular time-frame? We can help reserve you for a date and time the issue is most frequent in hopes it can be tracked at the time of the appointment.
