Fast questions (email, GPRS, WiFi...)

[Peter Nijs]

After a whole lot of tweaking I still cannot get an IP from my wireless 
router. My current setup looks like this:

/etc/network/interfaces:---------------------------
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
 
# The loopback interface
auto lo
iface lo inet loopback

# Wireless interfaces
iface wlan0 inet dhcp
wireless_mode managed
wireless_essid any
iface atml0 inet dhcp

# Wired or wireless interfaces
iface eth0 inet dhcp
   wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

iface eth1 inet dhcp

# Ethernet/RNDIS gadget (g_ether)
# ... or on host side, usbnet and random hwaddr
auto usb0
iface usb0 inet static
	address 192.168.0.202
	netmask 255.255.255.0
	network 192.168.0.0
	gateway 192.168.0.200
	up echo nameserver 192.168.0.200 >/etc/resolv.conf

# Bluetooth networking
iface bnep0 inet dhcp


/etc/wpa_supplicant/wpa_supplicant:----------------------------------------------
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=0

network={
     ssid="PN"
     scan_ssid=1
     key_mgmt=NONE
     wep_tx_keyidx=0

     wep_key0=<I'm not showing that!>
     priority=8
}


Now here's what I do:--------------------------------------------

While udhcpc is sending discovers I can see my router is leasing my neo a 
valid ip for 60 seconds each "sending discover".

Sometimes, in very rare cases I can get a decent lease. But that is not 
reproducible. I think it's happened three times to me the last three days.

Anyone knows how I could get an IP reliably?
