Quick noob question

Sorry if this has been asked before, but I just need a quick answer before I go home.

For the life of me I can't find the place to change the security key for my network.

I have windows 7 and a linksys router (got someone from Geeksquad to install it, so don't know too much about it). I just wanted to change the security key on my main desktop computer, so all my passwords on my laptop (sign in/connect to internet,etc) are the same.

So how/where do i go to change my security key? I tried looking through the control panel, but no luck. (no patience is more like it )

Thanks for any help

Usually the security key is first setup in the router's control panel. You need to know the IP or default gateway of your router for this, usually in the US it's 192.168.0.1 or 192.168.1.1 typed into the URL of your browser.

It can also be changed or adjusted in Windows 7 by going to the Network and Sharing Center, then look to the collum on the left and choose "Manage Wireless Networks" Once there you can choose a wireless network, click on it then you can use the Security tab and edit the security settings like in the picture below. Hope this helps.
