A bill that's composed as a consumer protection measure for Wi-Fi gateway buyers will likely become law in California: The bill has a vague set of requirements for manufacturers selling their Wi-Fi equipment in the Golden State to provide some documentation on securing their network. This law will likely only affect off-brand products; I haven't tested a wireless adapter or gateway in a few years that hasn't provided some form of warning and advice on this topic. Further, the Wi-Fi Alliance's Wi-Fi Protected Setup (WPS) will launch this fall for substantially simpler, no-password-invention-required WPA configuration. The law takes effect Oct. 2007.
This law is much better than Westchester County's highly misguided attempt to control the public airwaves by requiring weird disclosure on Wi-Fi networks, while misunderstanding the difference between link-layer encryption and firewall protection--but encoding that mistaken idea in law, anyway.
