Micro outages

I have been experiencing repeated micro outages for about a year now. It took a while to diagnose this as the problem but now it is very apparent it is the issue (in the past I thought it was my VPN to work but in fact it is the micro outage that disrupts the VPN connection). I cannot get through on the phone or through the chat function because the diagnostic tests show I have Internet and there is no local “outage”. By the diagnostic tests fail to pick up repeated micro outages. I need a technician to come out to check noise and signal leveles.
