Wi-Fi Finder is an app on both the Google Play Store and Apple App Store which finds, displays and allows users to connect to nearby Wi-Fi hotspots. Service providers such as Xfinity and AT&T provide Wi-Fi hotspot maps on their official websites.
Common locations where free Wi-Fi hotspots may exist include restaurants, hotels, banks, malls, department stores and libraries. Starbucks, McDonald's, Dunkin' Donuts and Applebees are just a few national chain restaurants known for providing free wireless connections to customers. Wi-Fi hotspots provided by mobile phone, cable, or Internet companies may require a password and user name to connect. This is be the same as the user's cable, phone or Internet online account log-in details.
If a Wi-Fi hotspot is needed and none are available nearby it is also possible to use a mobile phone or tablet as a hotspot using a method known as tethering. Tethering is supported by many modern mobile devices and service providers, although some may charge additional fees or may not support tethering functionality. A mobile hotspot device, such as Verizon Wireless' Jetpack, is specifically designed to function as a portable mobile hotspot, but it requires a subscription to a compatible wireless data network to provide connectivity.
