Internet drops continually

For the past few months, I have had repeated internet drops throughout the day.  At its worst, it is multiple times per hour, which makes working from home challenging.  I have called in multiple times and the only resolution has been for either 1)sending a refresh signal to my modem 2) manually restarting the modem myself.  I have taken the action to connect my modem directly to the coax line coming in from the street, which allowed my to bypass 5 different splitters in my house (I stream my content so this isn't an issue).  From what I have read, looks like I need to have someone come out to resolve.

Here's what my connection looks like:
