Internet drops multiple times per day randomly

Seems completely random, interrupts my work from home just about every day.

I have some modem logs and connection info. (Taken during a time when it is working, not sure if any of these numbers change when things go wrong)

Drops are 3-10 minutes long.

We pay for 250mbps package.

We've had techs out probably 4 times, issues were found each time, but this issue is persistent.
