Well thats not going to happen where i live. My wireless goes about 20 Meters from my room where the router is. I HIGHLY dout some guy is going to randomly stand outside my front door and do anything like that.
I couldnt even think that would happen to ANYONE! seriously all wireless connections from peoples routers dont extend that far. so people wont really access it. unless they camp outside your door.
Its all so over the top
You'd think some random guy wouldnt try open your front door at night, but you still lock it right? And breaking your wifi is quicker, more profitable and less risky than breaking into your house
