I had a laptop I wiped and set up with Windows 7 on our domain and, doing nothing special other than simple install, was able to connect to our wireless network, go to properties > security > advanced settings and select 'Enable single sign on for this network.' Now, having wiped another laptop and setting it up the exact same way, exact same Windows 7 install CD, and same network settings, the Single Sign On option is not available. In the same network properties > security > advanced settings tab it says 'Enable SSO' but I am not able to check or select anything in the area. I can only edit the part above it that says, 'Specify authentication mode:'. Any ideas on why I the SSO option is faded grey and not selectable but on another laptop with same programs and Windows 7 settings it is? Thanks!

Hi, I would like to know if the second laptop is in domain environment. If so, the configuration only can be modified by domain admin. If not, What user is logged on the second laptop? Please update your wireless adapter driver from manufacture's side and disable your security software to check the result. Also, refer to the following article and make sure the settings are correct. http://technet.microsoft.com/en-us/library/dd759246.aspx Best Regards, Niki Please remember to click "Mark as Answer" on the post that helps you, and to click "Unmark as Answer" if a marked post does not actually answer your question.
