Starlink works fine but suddenly turns to Intermittent internet until dishy is rebooted

Hello all, a long story short, We live in a remote rural area in the southern coast of Mexico. I persuaded my friend to get the starlink antenna. We were so happy when we did our first speed test we got over 200 mbps.

I told my friend that it is normal to get a few seconds of downtime once in a while. But as soon as we started to make use of the internet we started to get randomly intermittent internet service and never resumed to the previous steady speed before the failure until the starlink antenna gets restarted manually.

I told my friend to submit a report via the app but days later he got an answer that the problem was on his side.

Have any of you have experienced this problem? How did you fix it?

Thank you in advanced for any help.
