hello there!i have just purchased a wireless ADSL modem/router kit (D-Link). modem/router DSL-G604T and the wireless USB dongle DWL-G122. i have set up the network correctly (i think) and i am now struggling to set up the security features. in the settings it is asking for the Internet Provider Address, the broadband provider i am using is BT yahoo. how do i find out the internet provider address? what are the best security setting i can have between 2 computers in the same building? how secure is a wireless network? what should i be weary of using a wireless network? thanks
