    AutoAP

    A script to find open Wi-Fi connections and the strongest signal

    AutoAP is a script that continuously scans for open Wi-Fi connections, tests them for validity, and connects to the strongest signal. If the connection is lost, the script scans again and finds the strongest valid signal again, and maintains a continuous connection to the internet in a mobile or portable environment. The script paremeters are highly configurable, including ability to configure secure connections. AutoAP is an add on to DD-WRT that allows routers to continuously scan for and connect to open (and predefined WEP) wireless networks. Ultimately the goal is to develop an easily deployable firmware that facilitates fast and easy mesh network creation. Typically, you would use this script on your router while in Repeater Mode, Client Mode, or Client-Bridged Mode.
