I know there are a million posts like this here, because I've read what seems like thousands of them. I still can't figure out what equipment I need.
We have two computers currently connected to a broadband cable connection through a router in my office. We would like to be able to connect a third computer (that has a wireless card) and various PDAs with WiFi. I would like to keep the original two computers on wired connections and wireless for the rest.
We would also like to be able to share certain files among the various computers.
I also can't figure out the answer to a question I have. I know (or think I know) that wireless networks are easier to hack into than wired. If this is true, is there a way to protect the two computers on wired connections from anyone who might use our wireless network?
Although we have a small yard, our house is three stories plus basement, and we would like a wireless signal that can be used all over the house, plus in the yard. The current wired router is on the second floor, and we would like it to stay there.
Thanks so much for any information you can give me.
