First of all connect to your router with an Ethernet (RJ45) cable:
Some routers have the security codes fixed and these are normally displayed on the outside of the router.
Other routers allow the user to define or change the Service Set IDentifier (SSID) which is your wireless network name and of course the type of security such as Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA and WPA2).
To change any of your router settings, first of all you need access to the router’s control panel by browsing to the router’s IP address. Many routers will have the IP address displayed somewhere on the outside of the router. If not, you will need to read the documentation or contact the manufacturer for these details. Alternatively you could try obtaining an active routers IP address from your computer by going to Start > Run – now type in ‘cmd’ without the quotes (hit enter) at the black DOS screen type ‘ipconfig /all’ again without the quotes. The address shown against Default Gateway should be the IP address of your router.
Now open your browser and type in http://192.168.2.1 - this address is just an example and may not be the address of your particular router.
If you get the IP address correct you will be presented with a screen asking for the User Name and Password. You will need both of these before you can enter the routers heart.
Once you are inside, the world is your oyster. You should be able to change details regarding your SSID, how many wireless connections can be made (IP range), MAC Address filtering and of course your security settings.
If you have previously changed either your User Name or your Password and have forgotten or lost these details, your router can be returned to its factory default condition by pressing the reset button. This button is normally recessed to prevent any accidental reset so you will need to press and hold this button by using a straightened paperclip or something similar whilst the router is turned on.
