suddenly not getting advertised DL speeds with Arris SB6141 modem

I have the 150 Mbps down/5 up package and last week my speeds dropped down to 30 Mbps down or below. I am still getting 6 up consistently.

 

A tech came out and spent 2 hours at the house helping shake out the issues. he said the signal coming into the house was fine but I had a damaged coax cable in the wall run within my house that was causing issues. I hooked up the modem directly to the drop and my speeds are now 40-50 Mbps down and 6 up and peak speeds when connected directly to the modem but they're still frequently dropping. 

 

I have an Arris Surfboard SB6141 modem that I own outright. He wasn't able to advise me on whether my modem is malfunctioning or not. Xfinity support says that from their end everything looks fine and they don't know what the issue is.
