First what is a KC550 lg , laptop , deskop , mobile phone.
Im assuming phone have you synced with the wireless router ?
Connecting your LG phone to wireless Internet is easy to accomplish with phones that can receive Wi-Fi signals.
You may decide to use the Wi-Fi capabilities in the event that you do not receive the best signal from your wireless provider at your home or office.
If this is the case, then hooking up to a Wi-Fi network near you could provide you with a faster connection to the Internet and a more reliable signal to send e-mails, texts and pictures.
Press the "Applications" tab on the home screen of your phone.
Scroll down the list of applications until you reach the "Settings" option.
Press "Settings" to bring up the menu.


Locate and click the "Wireless & Network" or "Connections" option within the "Settings" menu.
Select the "Wi-Fi Setting" or "Wireless Manager" option, then select the network that you want to connect to and click "OK."
All of the available wireless networks within your range will appear.

Enter the wireless network password (usually located bottom of router) if you are connecting to a secure network.
Press the "Done" button followed by the "Connect" button.
