WLAN enabled?
some wireless routes require the WiFi to be enabled and default to DISABLE, the likely reason being that there's no security settings yet.
get your manual/cd to give you the IP address of the router
(eg 192.168.0.1) and the user/password
hardwire router to any system
use your browser to access 192.168.0.1/ (notice missing HTTP
you should get a page that has various tabs/settings
look for WLAN setup
enable wireless
if you do anything, PLEASE change the SSID to something other than the default, write it down, and DISABLE SSID broadcasting(hopefully your router supports this feature). This will psuedo-hide your WiFi from trival attacks. you SHOULD enable encryption, but read up on WEP/WAP.
be sure to SAVE settings when you'r done.
unplug the hardwiring, enable wireless on the system, and look for a signal,
you will have to MANUALLY configure the card to add the SSID you created above - - this is what will frustrate the trivial hacker - - playing with 'what is the SSID?' and that's what should drive them away.
