Put the primary SSID and the guest name on a small card near the TV stand, add which devices live on which band, and tuck a mini flashlight there for finding hidden buttons. Keeping a short “reboot order” note—player first, then phone, then router—helps prevent chasing your tail when you’re tired. The more repeatable your routine is, the easier it is to spot when something really changed instead of spending the evening toggling settings at random.
