Thank Johan DS! I enter a command from a link(https://wiki.archlinux.org/index.php/Wireless_network_configuration) you offer:
iw dev the screen display nothing, where something go wrong? In XP, wireless config is easy connecting cell phone to router is easy too, just enter password why it's so hard in Linux? I don't have kde or gnome, is there any GUI tool that make it easy and not rely on kde/gnome? the installer may have some nice program that config wireless? should i reinstall debian??
