After reading what I can find here about these issues, I still have a few questions. Background: Had to buy a new router (D-Link DI-524) yesterday, as my less-advanced D-Link died on me. I believe I have managed to make a MAC filter that only allows us on the network via the MAC addresses for our three computers, 2 PBs and a Mini. (Each computer has a separate MAC address for Airport and Ethernet, right? I put in all six addresses, so our computers would be allowed online via both of these methods.) I also think I managed to deactivate SSID broadcasting. I say think, because when I put each computer back on the network, I didn't see our network's name - I had to write it in, couldn't just choose it from a list. Of course, now the name shows up in the lists on our computers, even if I turn airiport off and on again, but I assume that's because I wrote it in and the computer found and was allowed on the network. What I can't seem to manage, is to activate either WEP or WAP without causing some problem that makes us suddenly not able to log on again. And though the router has this 802.1x business, I really don't feel confident that I understand that at all. My question: If I've managed to block SSID broadcasting, and have done the MAC filter correctly, is it reasonable to assume that I've protected the network, despite not having WAP in place (I know WEP is hopeless and can easily be cracked)?
