I had my win 7 computer set up for my home's wireless network and then I switched the router from WEP to WPA.I couldn't figure out how to change the networking settings for for the win 7 computer. I also could not find any way to remove the network from the list in computer so that I couldre-add it with the new WPA settings. I ended up re-installing the win 7 RC so that the computer would find the networkfor the "first" time.

You should be able to get to the stored profiles by opening Network and sharing center and clicking on the "Manage Wireless Networks" link in the left pane.Thanks,Alok ManchandaMicrosoft Corporation

I did find that section, but there's no option to remove a wireless network connection once it's set up. thanks,

Do you see profiles listed there? If you see the profile you want to edit then double clicking on it should launch an interface to edit it. If you are continuing to have problems, please cut and paste the output (will be long) of the below command in your reply. netsh wlan show all Thanks, Alok Manchanda Microsoft Corporation

You shouldn't have to remove it to change it. When you update your settings, you should be able to just connect with your new credentials.

In win7 to configure wireless network,use wireless zero configuration>>your SSID>>properties>>security is the path where you can change security settings for wlan in windows 7 OS.
