Why can't my dell latitude get wifi.

the connection to my house was terminated. Which connection was terminated?

Dell's are infamous for the use of setting a hard key (or a pair of keys) to start your wireless connection. Ensure that you have "flipped" the swtiches on. I believe it's a combination of a control key (blue letters) and function key.

Check the function keys to see if you see an antena icon printed on the key.

If after this is set you still don't get connection, search for a wireless network and make a connection.
