Locate free Wi-Fi networks by scanning for available networks using your mobile device, accessing an Internet directory of published Wi-Fi spots and frequenting businesses that generally offer the public free service. Most mobile devices allow users to scan for networks in range, providing a list of available connections.
Online search engines, such as OpenWifiSpots.com and WifiFreeSpot.com let users search by ZIP code for available public Wi-Fi spots such as libraries, government buildings, parks and transportation centers. These search engines also locate privately owned businesses that generally have free public access, such as restaurants, coffee shops, book stores and office supply stores. Many locations, including Mcdonald's, identify connection availability using notices, such as window signage and web advertising.
