That's a tough one, @nora_okgn. This looks to be specific to your home and without communicating with the techs, it'll all be conjecture. The specific details may be known to the field and backend teams, though (customer/tech support will generally have a summary of the work performed but not necessarily root cause). Do you still have contact with your installer? Perhaps they are able to offer insight.

My only caution is to make sure it isn't the booster. I have been having problems for 2 weeks. Router swap. Did nothing. Tech support wanted to swap sfp module next. I went on the booster to see that it was failing by checking logs. I don't know why tech support doesn't try that neat trick. I put in my own aftermarket AP and things started working well again. Just waiting to replace the booster because I want the MoCA link back. I do not trust tech support at all. They just factory reset and swap pieces with no real investigation.
