OK, we have a wireless router for our cable internet. Today, I was ordering something online, and filling out the info for the payment. (name, address etc..) you know how when you begin to type your info in, a drop down menu will appear with suggestions? (Usually those names which you frequently use). Well my next door neighbor's name appeared in the drop down menu! So now I know that he is obviously piggy backing on our wireless connection. Now I am not very computer savvy at all. Is he accessing our computer? I mean, if his name appeared in the drop down menu, does that mean that he is doing more than just borrowing our connection? I am assuming that for his name to appear on the drop down menu on our computer, he has to be accessing our computer somehow. Or can that happen just from sharing the connection? Sorry if this is a dumb question, but I have no idea. We have a Mac computer. HELP! I feel violated!
