Frequent signal drops

Gateway keeps internally resetting (20+ times daily).  Upside power reads above 54.5. Codes show WIFI VAP down and the the radio antennas reset, this causes service interruption.  This occurs every year.  A home tech comes out every year.  When the weather settles my service is fine. I requested a line technician, in app chat, but upon appointment verification it was determined that a home technician was scheduled. The outages are severely affecting home and work.
