In order to get more public Wi-Fi hotspots installed, NYCwirelsss contracted with the for-profit company Cloud Networks, which was staffed by some of the founding members of the NYCwireless community project. In the aftermath of the September 11 attacks in 2001 NYCwirelsss helped to provide emergency communication by quickly assembling and deploying free Wi-Fi hotspots in areas of New York City that had no other telecommunications. In summer 2002, the Bryant Park wireless network became the flagship project of NYCwireless, with about 50 users every day. By 2003 NYCwireless had more than 100 active hotspots throughout New York City. In 2000, guifi.net was founded because commercial internet service providers did not build a broadband Internet infrastructure in rural Catalonia. Guifi.net was conceived as a wireless mesh network, were households can become a node in the network by operating a radio transmitter. Not every node needs to be a wireless router, but the network relies on some volunteers being connected to the Internet and sharing that access with others. In 2017 guifi.net had 23,000 nodes and was described as the biggest mesh network in the world. In 2001, BCWireless founded to help communities in British Columbia, Canada, set up local Wi-Fi networks. BCWireless hobbyists experimented with IEEE 802.11b wireless networks and antennas to extend the range and power of signal, allow bandwidth sharing among local group members and establish wireless mesh networks. The Lac Seul First Nation communities set up their Wi-Fi network and constituted the non-profit K-Net to manage a wireless network based on IEEE 802.11g to provide the entire reserve with Wi-Fi using the unlicensed spectrum in combination with licensed spectrum at 3.5 GHz. For the most, early wireless community projects had a local scope, but many still had a global awareness. In 2003, wireless community networks initiated the "Pico Peering Agreement" (PPA) and the "Wireless Commons Manifesto". The two initiatives defined attempts to build an infrastructure, so that local wireless mesh networks could become extensive wireless ad hoc networks across local and national boundaries. In 2004, Freifunk released the OpenWrt-based firmware FFF for Wi-Fi devices that participate in a community network, which included a PPA, so that the owner of the node agrees to provide free transit across the network. There are at least three technical approaches to building a wireless community network:  Wireless equipment, like many other consumer electronics, comes with hard-to-alter firmware that is preinstalled by the manufacturer.
