[poky] WiFi setup

[Gary Thomas]

Pardon me if this is not the best place to ask about this, but
since I'm building using Poky...  Feel free to send me elsewhere
(with pointers!) if there's a more appropriate list.

I now have a WiFi USB dongle which I think the kernel is happy
with, at least I get the 'wlan0' device running.  I'm not running
network manager, I'd like to just get it going "raw" via ifup, etc.

Sadly, when I try it, it doesn't work.  Here's what I see:

   root at cobra3530p60:~# ifup wlan0

   root at cobra3530p60:~# iwconfig wlan0
   wlan0     IEEE 802.11bg  ESSID:"test adhoc"
             Mode:Ad-Hoc  Frequency:2.412 GHz  Cell: B6:42:15:B2:E8:91
             Tx-Power=18 dBm

             Power Management:on

I have the default settings in /etc/network/interfaces for wlan0:
   # Wireless interfaces
   iface wlan0 inet dhcp
           wireless_mode managed
           wireless_essid any
           wpa-driver wext
           wpa-conf /etc/wpa_supplicant.conf

I did not change /etc/wpa_supplicant.conf

I've not found much in the way of documentation on how this works,
but I think the [first] real problem is that the interface is in
the wrong mode - Ad Hoc instead of Managed.

Does anyone know what I need to do to get this going (I think I
know how to set the details of things like my AP SSID and keys),
I just don't think I'm getting that far.

Thanks for any ideas
