AutoAP is a script that continuously scans for open Wi-Fi connections, tests them for validity, connects to the strongest signal, and makes it available locally. 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.
What is this good for, you ask? Look at "The WiFi Predator" at the bottom of the page.
Note: My router is Buffalo WHR-HP-G54, but the procedure is the same for any router that is supported by dd-wrt.
Here are the steps you need to follow:
Select any router name and host name you want.
Make the Local IP Address something like 192.168.73.1
Click Save and then Apply Settings, wait for the reboot and then log back in to the new IP: 192.168.73.1
Add a Virtual Interface and then configure everything like this and then click Save:
The Wireless Network Name (SSID) for the Physical Interface could be anything, this is going to be overwritten automatically.
The Wireless Network Name (SSID) for the Virtual Interface is going to be the SSID that you connect to when you want to connect to the internet with your mobile device.
Wireless Security (configure security just for the Virtual Interface). This is what you are going to connect to with your mobile device.
Change the Preamble to Short and TX Power to something like 100-200:
Uncheck first (make sure you do this) everything on the Security->Firewall page and then Disable firewall. Click Save.
In the Commands box write /jffs/autoap.sh & and then click Save Startup button
Reboot your router and then after 2 min go to:
You should see something like this:
If you see this page, this means SUCCESS! Congratulations.
Next step, get the antennas from here or here and connect to any open Wi-Fi connection from a mile or more!
