 I'm using the Wifi-method described in

 http://wiki.openmoko.org/wiki/Neo_FreeRunner_Wifi#Using_WPA_and_.2Fetc.2Fnetwork.2Finterfaces

 i.e. having a working config file /etc/wpa_supplicant/wpa_supplicant.conf
 for all my known access points (which is just a copy of that I'm using
 daily and stable in my two FreeBSD based laptops); and I'm trying to bring
 up the eth0 with

 # ifup eth0

 this works very unreliable; in (let's say) 8 of 10 cases it can't
 associate to the AP, even not after fresh re-boots and independently if
 the AP at my home works with WEP or in my office with WPA;

 I'm attaching:

 relevant part of /etc/network/interfaces
 iface eth0 inet dhcp
         wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
 pre-up iwconfig eth0 essid off
 up route del default gw 192.168.0.200
 down route add default gw 192.168.0.200
 iface eth1 inet dhcp

 relevant part of /etc/wpa_supplicant/wpa_supplicant.conf

 network={
         priority=99
         ssid="santaclara"
         key_mgmt=WPA-PSK
         psk="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
 }

 output of 'iwlist eth0 scan'

 eth0      Scan completed :
