Downstream power level good, Upstream bad

Hey all,

 

A week or so ago, Xfinity came out and fixed the node/lines for my neighborhood. After the upgrade, my signal levels were dramatically improved. My downstream power level went from -6 dBmV to roughly -1dBmv on most channels. My upstream went from roughly 50/51 down to 41/42. Yesterday I noticed my downstream levels still look good, however my upstream levels shot back up to 50. Im not sure if this is still an ISP issue or I should be checking something inside my home? Any tips? I have already hard reset the modem with no luck. Thanks. Screenshots attached.

    Have the ISP check the signal and line quality UP to the modem. 
    Be sure there are not coax cable line splitters in the between the modem and ISP service box. 
    Be sure your using good quality RG6 coax cable up to the modem.
