You can try to go the "manual" way to see if you get better results: -bring up your wireless interface, if it s not already up 'ifconfig' (if it doesn't appear here, means it is not up) 'ifconfig -a' (you should see it here, as this command lists all the available physical interfaces on your machine. Then) 'ifconfig WIRELESS-INTERFACE-NAME up' (to bring it up). -Then, once up, you can, as ken said, use iwlist to know about the AP in your vicinity 'iwlist scan' You should see mac-donald's AP essid name in the list you get from iwlist. -Finally, for mac-donalds, I saw on their page they re isn't any encryption and password to connect to their AP, so you just need to run 'iwconfig WIRELESS-INTERFACE-NAME essid MACDO-ESSID-NAME' and then dhclient to get an IP(with the -v flag to be sure you obtained an IP address) 'dhclient -v WIRELESS-INTERFACE-NAME' -Finally_2, open your browser and you should see mac-do HP, and a 'connect' button to connect from there. There is a detailed explanation to connect manually on crunchbang, under the three main methods (no password and no encryption, or WEP or WPA). Here is the link http://crunchbang.org/forums/viewtopic.php?id=16624 Also, you might have to use 'sudo' for all those commands as you need to be the root user to run them. Also_2, stop all the other wifi-network-related daemons as they might get in the way when you try to config manually(wicd and others if you have).
