I've got an interesting problem here with My MacBook running the Knoppix 5.3.1 DVD. The wireless card is definitely recognized, but I can't get an IP address.
First things first... when I do an ifconfig fresh after boot only the loopback adapter is shown. So I select "Network/internet configuration" and click the wlcardconfig option. This brings up the "Wireless Configuration" dialog which shows "network card: ath0 (AR5418 802.11abgn Wireless PCI Express Adapter)".
When I click on ESSID, I see a list of nearby wireless networks, and mine is on there so I select it. Then I enter the WPA2 shared key (note: this end result is the same when I select an open network instead of an encrypted one that doesn't require a password). Then I click "IP: Set/Connect". This produces a popup with "ath0 Atheros Communications, Inc. AR5418 802.11abgn Wireless PCI Express Adapter) Obtain address automatically (DHCP)?" I click yes.
The dialog sits there for a minute, then I get "No answer fro DHCP server." and the Wireless Configuration dialog appears again. Click Quit. The Network-Check dialog works again for a minute, then I get "Automatic reconnect to the Internet using WLAN (wireless) setup? Hit Skip for manual setup." I hit "Yes".
This produces the following with ifconfig... notice my wireless card hardware is listed twice, as both ath0 and wifi0. The wifi0 device is actively receiving and transmitting (though I don't know to where!). Does anyone have any ideas here? Thanks much!
