right now only my main computer. Everything else has been disconnected from the router. It is password protected.
I live in the country so no one close enough to be trying to use my wireless.
Since i am in the country i am connected via a radio receiver type of device..sorry forgot whats it called. It sits on top of the roof pointed to the ISP's tower. I realize its not going to be the fastest way of getting internet but right now my speeds are so up and down it s worse than dial up.
