I bought a set of three "mesh" wireless routers recently. I used the same network name and password as before, but the new routers required me to log in each device individually. Now I'm wondering if I should have set up a VPN for my house. If I had known I was going to have to reconnect all my devices individually, I would have changed the password.
I don't understand VPNs as well as I'd like to. Any advice? Do I really need one in a rural home?
