How do you secure your wireless router?

You don't on a standard router, unless you have a server issuing dhcp to the machines. But you only need to set the router admin password and nobody can use the page anyway. For normal use that and setting an encryption key controls all use of the router.

If you want to access the router's configuration page, you need to connect the computer to it using an ethernet cable and at a Command Prompt, type ipconfig. Take note of the Default Gateway which consists of 4 groups of numbers between 0 to 255 separated by a dot. That's the router's URL. On your browser, type http:// and the Default Gateway, (ex. http://192.168.1.1)./

Before you can get in, you will need to enter the router's username and the password. The default, if they were not changed, may be found in this link:

However, if the defaults are not being accepted, you need to reset the router by pushing a pin or tip of a pen/pencil/paperclip inside a hole behind it. Hold it for 15-30secs until the lights turn off and back on. Once you are in, you will be able to assign the wifi password and even select which wireless devices can connect to it even if those devices use the correct password. You may also set the router to allow or disallow configuration by remote devices like on my router which I can change the settings even if I'm not connected by a cable.
