5G Gateway not asking for password

After setup of 5G Gateway Wi-Fi and creating a username and password initially with my phone, all of my other computers were somehow connected to it automatically. I never selected it or put in a password which means other people will access it. How do I fix this?

Something seems strange.  Computers don’t normally connect automatically unless the network connection was established beforehand.

Are you using the same SSID and password credentials from a previous router?

Probably best to do a factory reset on your gateway, and establish a new SSID and password never used before.  That should force your computers to reconnect only by you providing your new credentials.
