My parents left their wifi router on the same password for 6 years and I finally saw why that mattered
Went home to Sacramento last month and poked around their router admin page out of boredom. Turns out 14 devices were connected, and 5 of them were not ours, some neighbor's smart TV and random stuff they never approved. I changed the password and set the admin login too, and within 20 minutes 3 of those devices dropped off. So now I'm wondering, how often do you all actually check the connected device list on your own router?
