when you say ip/config you mean wifi properties and internet protocol properties right ?
if so select obtain ip address auto and select obtain dns auto.
if thats not what you mean...goto control panel ..open network connections...click on ur network connection ...in the list at left select change settings for this connection...in network properties scroll to internet protocol..double click to open..select obtain ip auto and obtain dns auto.
there are other ways to fill in fields but you need relevant info..
there are programs which can show u ip's but most require a special driver.
incidently if you choose ip and dns auto you will not see ip address but when connecting to network you will see aquiring ip address please wait.
if for some reason you still cant connect go to a place where you know have free internet access and connect there then net connection will be configured
