i'm getting internet access through comcast, but i think the apartments surrounding mine are using my internet because my connection is bad/slow. most of my neighbors have their internet password-protected; how can i password-protect mine? thank you!
Are you using a wireless router if so which one.
If so like the poster above type in your IP address. Each company's router will have a different interface. Look around and look for a category for wireless and there should be an option to set a password.
