Type “ipconfig” and it will show you the IP address. To check connectivity the best way is to use our old friend “ping”. Type ping ‘anyaddress’, replace ‘anyaddress’ by an IP or a domain like google.com if the box has internet. If you get a Reply than is has connectivity if you get request timed out then something is wrong.
One thing to remember is that by default ping uses a packet of 64 bytes to do the ping. This may be sucsseful on the congested network and not show you why other traffic is failing. It is also a good idea at times to remmber the -l switch and increase the packet size of the ping to its maximum of 64000 bytes. Becareful not to exceed the MTU of the network however.
