How do I hide my wireless internet from everyone else ?

[Tony RB]

Your d-link router/modem can be set up to give other people their own connection to the Internet through the router, so they can have their own user ID and password to connect to the Internet and not use your devices, or use their devices on your user ID.

You are not going to be able to hide the existence of your connection.

The wifi is a radio signal. Anyone with a wireless device can see the presence, that's how hackers are able to look for wifi to try to copy or hack into. Your neighbors will be able to see the presence if the signal is strong enough to reach their devices.

Sorry.
