My city (Aurora, IL) is on the verge of entering onto a contract with MetroFi for free city-wide Wi-Fi service. How has MetroFi been to deal with? How reliable is service? Any problems using VPN? How annoying is the ad banner that comes with the free level of service? Have you heard of any security issues? This is moving pretty fast here, so if there's major problems with MetroFi I want to let my alderman know right away. Thanks!
