Have a thinkpad R61 for my child's school aptop program. My child changed network setting on laptop (I think). Can no longer connet to internet through wireless router (through my destop). Messaage says "settings saved on this computer for this network do not match the requirements of the network". I tried to setup a connection. I entered my desktop network name (SSID) and network key but cannot get changes to take. I can connect (wired) laptop to router and access the internet but not though wireless. What can I do?
