Many hotels and cafes offer wireless Internet connections as a service to their customers with laptop computers. These commercial hot spots have access points within their facilities. The access points are routers with wired connections to a WISP that serves commercial locations. Typical WISPs include independent providers and cellular phone companies.
You can use a laptop that runs the Solaris OS to connect to a WiFi network that is offered by a hotel or other commercial hot spot. Ask for instructions at the hot spot for connecting to the WiFi network. Typically, the connection process involves supplying a key to a browser that you launch upon login. You might have to pay a fee to the hotel or WISP in order to use the network.
Commercial locations that are Internet hot spots usually advertise this capability to their patrons. You can also find lists of wireless hot spots from various web sites, for example, Wi-FiHotSpotList.com.
