I followed a tutorial about how to do this and every time I Go to control panel, Network and internet, network connections and right click 'wireless network connection' and click on 'properties' it says 'you do not have sufficient privileges for configuring connection properties. I followed your steps about how to deal with this: http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Windows/XP/Q_23466093.html
but when I get to step 4 (click OK) it says 'Access is denied'.
when I type in GPEDIT.MSC, it says 'windows cannot find 'GPEDIT.MSC', Make sure you typed the name correctly and try again.
Thank you very much for your help.
