Internet connectivity disconnects randomly every 5-30 mins

The line quality of the cable seems to disconnect the internet all the time causing annoying interruptions.

I have to move the cable going from the wall to the modem and get the right spot for data to flow, if its in the wrong position it disconnects more often.

The disconnecting randomly has started since December, but now its progressively getting worse. 

The modem/router is fine, we have a completely new one, ethernet cable is fine, only thing that affects the connectivity is the cable that runs through the attic and into the modem.

Modem: Arris Touchstone TG2472

(When the network disconnects, Upstream channel 4 disappears, sometimes other upstream channels are gone as well.
