I have a Linksys WRT54G(L) flashed with dd-wrt.

On my neo, I use this script to connect:

#!/bin/bash
/sbin/ifconfig eth0 192.168.3.202
/sbin/route del default
/sbin/route add default gw 192.168.3.1
/sbin/iwlist eth0 scan
/sbin/iwlist eth0 scan
/sbin/iwconfig eth0 essid dd-wrt4
sleep 3
/sbin/iwlist eth0 scan
#echo "nameserver 195.159.0.100" >/etc/resolv.conf

It always work, but sometimes I need to run it twice.
I think that is good.
To compare, I need this script for my laptop:

#!/bin/bash
ifconfig wlan0 down;
route del default;
ifconfig wlan0 192.168.3.184;
route add default gw 192.168.3.1;
iwlist wlan0 scan; sleep 3;
iwlist wlan0 scan; sleep 1;
iwconfig wlan0 essid dd-wrt4;
sleep 1;
while `iwconfig wlan0 |grep Link\ Quality:0`; do
	ifconfig wlan0 192.168.3.184;
	route add default gw 192.168.3.1;
	iwlist wlan0 scan; sleep 3;
	iwlist wlan0 scan; sleep 1;
	iwconfig wlan0 essid dd-wrt4; sleep 1;
	iwlist wlan0 scan; sleep 1;
done

So in general, it helps to scan before associating:)
