Free wifi for disabled veterans and service animals.
Use Waircut and Atheros Jumpstart with pretty much any USB wifi adapter, see cantenna, to audit WPA2 wifi networks from a Windows system. A bit dated tables and can take hours but its stable.
If you dont have nethunter or pwnphone, or a dstike watch, any salvaged laptop, minipc, arduino, or raspi, you can still help the veterans, disabled, and homeless cross the digital divide by liberating broadband wifi from the paywall of classist tech economics.
