People usually get confused between a router login and a wireless login, they are two different logins.

Router = Configuration
Wireless = Network login

Windows:

Code:
Start > Run > cmd > ipconfig
Default gateway: 192.168.1.1

Linux:

Open the terminal and type:

Code:
route -n

To log in:

Open up your web browser, (Internet explorer, Firefox, Chrome etc) and put that IP address in your address bar: http://192.168.1.1

You should see your routers log in page or a login box will pop up.

Some default log in info:

admin
*blank

admin
password

admin
admin

Usually the Username and Password should be on the back of your router.

http://www.routerpasswords.com has a huge list of router makes and username/password combinations. After logging into your router it is recommended to change your password.

Once you’ve logged in you can change the wireless password, the SSID name, port forward etc.
