Solve : add password to or disable network?

1.	Solve : add password to or disable network?
Answer» This was set up by a friend who is no longer available to assist me with this. I have two networks set up in my house, one is invisible, you have to know it so you can LOG into it. The other is a "guest NETWORK" that has no pw, you can just jump in. I would LIKE to add a pw to it or disable it so i have some control over who USES my connection. I get my internet through a comcast and have a Linksys ROUTER. I have been in my setting in the control panel and network sharing options but can't figure it out. If anyone can help I'd appreciate it. Thanks MarkTypically router settings are dealt with using your browser. Typically, the router will be accessible by going to http://192.168.0.1 or http://192.168.1.1 However they have another username/password combination. Unless they left it for you, that could be a problem.Look at the bottom of the router.What is the model number of the router. Linksys model BEFSR81 ver 3
