Internet Constantly Down for Months

My internet has been going down for 5-240 minutes at a time intermittently for multiple months now. I’ve had many techs come out and have had the following done already:

1) replaced line to house and buried last year

2) replaced the outlet into the house

3) replaced the coax in the house to the modem

4) replaced the modem

5) had an attenuator installed

5) had that attenuator replaced with a different one

The new modem is an SB6190

Here are some logs from the modem, it’s up right now but was down just a bit ago.
