My connection drops randomly—is it just me?

I've been using one of those mesh router systems for a couple months now, and at first it was awesome, like full bars everywhere in the house. But lately, it's gotten kinda flaky... I'll be streaming something or gaming and boom, connection drops for like 30 seconds. Super annoying, you know? Wondering if it's just my setup or if anyone else noticed this kinda thing with mesh routers.
