Wireless networks, or Wi-Fi networks, are popping up all over the country from national hotel and restaurant chains, to places like Philadelphia and San Francisco, which plan to blanket the entire city with wireless capability. As a service to ABCNEWS.com readers, we've compiled a list of public Wi-Fi access points in the nation's 30 most populous cities. With Wi-Fi services in flux and with many networks planning to go live in the near future, some of this information may be out of date.
