Frequent dropped connection.......again!

I am once again experiencing frequent dropped internet connection.  I hope it doesn't happen as I'm writing this.  It seems to happen at least once a year at various times.  My connection drops, I reset the modem only to have it drop again.  It may run for maybe a day and then it will drop suddenly and frequently.  Anyone out there experiencing the same?  It is very frustrating.  Once it happened while I was online taking a TIMED exam and I didn't finish in time because of the drops.  I'm seriously considering changing to another internet provider, but I don't know if that will make a difference.
