Frequent Short Term Disconnects

Hi, been having some internet issues lately and was hoping to get them resolved. Recently replaced modem due to frequent service interruptions. It resolved the issues for some time but now I'm faced with a new issue. My internet cuts out for 30-60 seconds multiple times per day. This has been occurring with steadily increasing frequency. This is a wired connection, directly to modem, no splitters. Here is a copy of the modem log:

    Hi Sargon, I can take a look at the modem signal and see what's going on with the connection dropping out. Can you send an email with the name and address listed on the account to cox.help@cox.com? Thanks!
