HS103P3 causing WiFi network instability?

After installing 6 HS103P3 smart plugs throughout our home I started experiencing WiFi network instability. Not sure if they are the problem just checking if others have experienced similar issues.

Like everyone else, I am working completely from home and am on different virtual calls throughout the day. What happens when I am on one of these calls is my outbound video will freeze, my voice gets choppy/robotic and whatever app I am using displays their message concerning network instability. I experience this with all the apps (Teams, Zoom, Skype, Slack) used. The instability occurs EVERY 15 mins like clockwork. And its generally right around the 15 minute mark (10, 10:15, 10:30, 10:45).

Anyone experience anything similar?
