Reply #75: how using your router is perfectly acceptable and not trespass

[Clovis Sangrail]

It is not illegal for my adapter to broadcast packets that your router can hear, just as it is not illegal for your router to broadcast packets that my adapter can hear.
These broadcasts are made into public spectrum and are perfectly legal (provided they aren't too loud).

While a argument can be made that my adapter is broadcasting packets specially crafted to elicit a response from your router, the same argument can be made that your router is broadcasting packets specially crafted to elicit a response from my adapter.
