Validating identy

Can anyone out there shed some light on this problem?

Right click on the network icon, select properties, then the tab for Authentication. If you have an antivirus with firewall, make sure to also deactivate windows firewall.

I moved the selection tab to WPA2 only and keep the rest the same and no luck.

I am sharing a secured wireless internet connection and the signal is strong.

but it keeps on bouncing on the icon activity when I bring up the status it has a big red ?
