Bought new computer and need key number for wl-520gc

Hi! there is a possibility that the wireless network of your router is secured. to check on the setup page of the router, u need to type the ip address of the router ex-192.168.1.1.. to check the ip address of the router, connect the router directly to the router and click on start, run and type cmd, dos prompt will pop up and from the dos prompt, type ipconfig/all and it will list the ip address, subnet, default gateway.. the default gateway is the routers ip address. once u got it, pull up a browser and type at the url- the ip address of the router and enter.. it will ask for the username and password, by default the username is admin and the pass, leave it blank then it will show the setup page of the router and you have to go to the wireless settings, on the wireless settings will show the type of security and password u have.. i hope this will help to solve ur concern..
