I WANT OT PUT PASWORD TO MY WIRELESS BROADBAND ROUTER SO ONE CAN ONLY OPEN OUR COMPUTER AND SELECTED PEOPLE CAN ONLY USE THE WIRELESS CONNECTION.HOW CAN THIS BE?

Network security key
Some later model wireless routers have the Password (ie.Encryption key) and the SSID already configured in the wireless router and this information is printed on a label on the bottom of the router.
These settings can be used to configure the wireless card and wireless adapters in your computer/laptop.
If these settings do not suit you, then it can be changed to suit your requirements.
The encryption key secures your data and wireless connection from unauthorized access.To configure the wireless settings in the router, connect a LAN cable from your computer to the wireless router, then open a Browser on your computer and enter the router's configuration IP address, then enter the admin login and password and then go to the wireless settings and configure the SSID and Encryption key.
The router's encryption key can be a Passphrase or the WEP or WPA or WPA2 key.If you use the Passphrase method select either WEP or WPA or WPA2 to generate the encryption key. You can enter the WEP or WPA or WPA2 key with 8 to 63 ASCII characters or 64 Hex digits.
Most people use Passphrase which is easier to remember eg. I was born in January 1988.
The strongest and latest security is WPA2, the weakest and oldest is WEP. To connect to your wireless router from the computer/laptop, configure the wireless card in your computer/laptop with the router's wireless settings ie SSID, plus the WPA or WPA2 encryption key. Then computer/laptops can communicate with your wireless router. http://www.fixya.com/support/r10267861-network_security_key

If your trying to connect wirelessly with your laptop make sure that you have the following information of the router;
1. Wireless network name or SSID
2. Wireless security settings; WEP 64/128 bit ot WPA

If your not familiar with the settings then you may need to access the setup page of your wireless router. Hardwire the laptop to the router or if you have a main computer that is already connected with an ethernet cable, open Internet Explorer or Mozilla Firefox or any web browser you are currently using. On the address bar type http://192.168.1.1 (router's default IP), then you will receive a pop up asking for a username and a password, there is no username and for the password type "admin" then click the Wireless tab on the router and check the basic wireless settings, if your not comportable with the settings then change the following; SSID - use a name that is easy to remember, Channel - 1,6, 11 is ideal, then for the Wireless Security choose WPA Personal and enter a 8 digit WPA Passphrase(pasword), remember to click save settings every tab that yuo go to or else the settings will na take effect. Then check if the laptop will detect the signal of the router and when it prompts you for a password or network key, just enter the 8 digit code that you have configured earlier.

If you have further questions regarding the setup of the router just post a reply and I'll to give you a response if my sched will allow me.

Hope this will atleast provide you with some idea in setting the router properly for your laptop.
