Packet Loss on a regular basis

I have been around the flag pole with Xfinity and this packet loss is just terrible.  I get 30% or more packet loss on a bridged modem that is brand new.  The cable is also brand new and the tech cut all the connectors off and added new the last time I tried.  There is a dud amplifier in this neighborhood and it happens when the temperature gets above 65 and during afternoon hours.

 

I'm a network engineer and this is textbook degrading cable plant.

Water ingress into a connector or failing amplifier behaves exactly like this.  

Surely they monitor this neighborhood equipment?  Don't send the guy at 8 am, send him at 2pm

If you call Comcast, they want to fix your modem or say, hey it looks fine now but this is chronic behavior during high congestion.  And they want to upsell from my 1Gbs to 2.5Gbs, uh huh.
