Various technologies described herein pertain to managing and accessing a community Wi-Fi network. The community Wi-Fi network can include sharer computing devices in differing local networks that share respective network bandwidth capacities with consumer computing devices. Feedback information pertaining to network bandwidth capacity available at different geographic locations covered by the community Wi-Fi network can be collected and evaluated to enable generation of maps for visualizing coverage of the community Wi-Fi network. A consumer computing device can display a map that includes visual information pertaining to the geographic coverage of the community Wi-Fi network relative to a geographic location of the consumer computing device. Community Wi-Fi network coverage can be analyzed to detect geographic locations at which network coverage is desirably added; network coverage can be added by incentivizing a potential sharer computing device to opt in to share network bandwidth capacity or controlling beamforming of sharer computing device(s).
