Could it be that whoever used it last changed the selection in the TCP/IP properties from "obtain DNS server address automatically" to "use the following"?
Suggest you go to start- contoll pannel-network connections then right click on the wireless connection select properties select TCP/IP click advanced and check that the box that says "obtain DNS server address automatically" is checked.
