I have a Macbook (running OS X 10.4.9) and just finished connecting it to the modem/router box thing that was supplied by my internet company. I followed the onscreen instructions and the whole hardware installation took me about fifteen minutes - and yes it works fine; my MacBook now connects wirelessly with the router thing.... But how the heck do I go about securing the connection? If anybody could help me out here I'd really appreciate it - and I'll add, as well, that I have no idea what the hell I'm doing here. All I know is that, so far, I've never had to type in any sort of a password? That's a bit odd, isn't it? Also, how do I find out if anybody else has been logging onto the net via my connection - does OSX maintain a log file for this somewhere?
