Could T3 timeouts every 5 minutes and downstream dBmV power averaging ~13 be causing internet to drop every few minutes?

New modem. Have paid to updgrade speeds twice now and internet is still giving is problems. Starting to suspect it's an ISP issue but I'd like some input. Thanks!

T3 timeout errors are caused by too much noise signal on the upstream channel. ... If the cable modem cannot raise its upstream transmit power level to a level that allows successful communication within the maximum timeout period, it resets its cable interface and restarts the registration process. Did you also swap coax cable when swapping the modem? If you have another coax outlet you can also try that.

    I have not tried another coax cable, but bought a new one since I am not sure of the age/condition of the one I have. It is connected directly to the drop from the pole so I hope this fixes it!
