Depending on the HotSpot location and network setup, connecting to a Wi-Fi network can be very easy and automatic, or it can be a manual process that requires you to change your network name, password and security code.
If you know a wireless network is operating where you are hooking in, first ask the appropriate person at that location if there are special instructions for signing on to the network.
If you are running Windows XP on your laptop, it should automatically scan and recognize the local Wi-Fi network and prompt you to log onto it. If you are using any other operating system, you may have to perform a manual scan to find an available network. Depending on your card and the card's manufacturer, you may need to run your Wi-Fi management utility to create a new network location. (Most Wi-Fi systems allow users to create and retain the network names, security settings and passwords for different network locations in their computer.) You simply select the correct network location and your computer will be able to connect. See your manufacturer's manual for specific instructions for your system.
