Is there anywhere I can look to see if I have any configurations set? I can log in as

user:'user'
pass:''

And look at stuff, I think without restriction, and not change anything. It has this 'Wizard' thing which sets an admin pass, the time zone, the internet connection, and wireless LAN connection.

What is the 'WAN connection side'. Does this stuff require any wierd information which will not be provided to me? I don't think I have a user/pass to connect to my ISP, I have a cable connection, but my knowledge of networking is almost nothing.

On this emulator here: http://support.dlink.com/Emulators/di624/ everything looks mostly the same except the WEP encryption keys, MAC address, DHCP client list, WAN IP/Subnet/Default Gateway/DNS, and probably a few other things. Anything I take note of? Will all the computers (4) using the router be able to use the router after I reconfigure it properly?
