You guys were in the Madison Park (Seattle) neighborhood installing fiber on Monday, 6/22. Ever since then, I've been experiencing brief drops in the internet every few hours.
During my work day, it drops out two or three times -- this is very disruptive when I'm on an important video conference call for work. Looking at our neighborhood (NextDoor) forums, it looks like neighbors are experiencing similar outages.
I have a similar issue that my wifi disconnects every hour for about 1 min. It turns out to be a problem with my network adapter driver in my Windows 10 computer. Just try "roll back driver" or "update driver" (search online how to do it specifically). For me it solved the issue
Hope this helps
