Internet consistently down

Don't know what to do. My internet is goes down consistently. Sometimes it's an outage and other times it's intermittent. It's causing me a lot of problems as I work from home. Also, I'm so sick and tired of Cox's blanketed "people are working from home and schooling at home due to Covid."  It's a total copout. Additionally, my speed is low and I never measure what I'm paying for. 

Cox is of no help to me and at this point I just want to switch ISP's. Any help/recommendations before I do so? I've heard my alternative isn't any better. Also, yes, my modem is new and I'm the only one working from my home.
