My network card, Intel pro 10/100 ,  tells me that the network cable is unplugged.   How can this be, it is internal?   How do I fix it?

Problem #2 When I click on Network Connections I get a screen that says "LAN or High Speed Internet"  NOT Wireless Network Connection

Problem #3   When I click on Change settings of this connection in the Network Tasks box, I get a "Local Area Connection Properties" wiinndow instead of the Wireless Network Connection Properties window.   This window does not have a Wireless Networks tab.  It has the following tabs  General, Authentication, and Advanced.  How do I find the Wireless Network Connection window? 

Thanks for the help.
