frequent/daily internet dropouts

I've been suffering with this problem for months.  Frequent dropouts, internet just stops working then comes back up.  Interrupts my gaming sessions or movies or whatever.

tech support always tells me "its working at the moment, so there's nothing we can do to help."

I find this unacceptable!

my router (Netgear C7000) logs are loaded with errors.  Pleas, connect me with someone beyond the basic "try rebooting your modem" tech.  I am not a toddler.
