My Wireless Script Wont Work.....anyone??

ive been trying to write a simple (at least i thought it was) script to launch my wireless usb under ubuntu with kde. im using nano.

when i run it from a terminal it works fine, but it just wont run from the script. there is a caveat, but first heres the script.

-------------------------------

#!/bin/bash

sudo ifconfig wlan1 up
sudo iwpriv wlan1 set AuthMode=WPAPSK
sudo iwpriv wlan1 set EncrypType=TKIP
sudo iwpriv wlan1 set WPAPSK=1111111111
sudo iwpriv wlan1 set SSID=network
sudo iwpriv wlan1 set NetworkType=Infra
sudo dhclient wlan1

---------------------------
this is the output

There is already a pid file /var/run/dhclient.pid with pid 13451

1 packets transmitted, 0 received, +1 errors, 100% packet loss, time 0ms

No working leases in persistent database - sleeping

--------------------------
now heres the twist:

sometimes it asks for a password, sometimes it doesnt

also, if i run the script up to here:
sudo iwpriv wlan1 set NetworkType=Infra

stop it, and run sudo dhclient wlan1 in a terminal, it works!

ive tried running it with sh script, ./script but still no joy. its probably something simple im just missing but im stumpped.

thanx if anyone has any ideas.

RDS-PING(1)						    BSD General Commands Manual 					       RDS-PING(1)

NAME
rds-ping -- test reachability of remote node over RDS SYNOPSIS
rds-ping [-c count] [-i interval] [-I local_addr] remote_addr DESCRIPTION
rds-ping is used to test whether a remote node is reachable over RDS. Its interface is designed to operate pretty much the standard ping(8) utility, even though the way it works is pretty different. rds-ping opens several RDS sockets and sends packets to port 0 on the indicated host. This is a special port number to which no socket is bound; instead, the kernel processes incoming packets and responds to them. OPTIONS
The following options are available for use on the command line: -c count Causes rds-ping to exit after sending (and receiving) the specified number of packets. -I address By default, rds-ping will pick the local source address for the RDS socket based on routing information for the destination address (i.e. if packets to the given destination would be routed through interface ib0, then it will use the IP address of ib0 as source address). Using the -I option, you can override this choice. -i timeout By default, rds-ping will wait for one second between sending packets. Use this option to specified a different interval. The timeout value is given in seconds, and can be a floating point number. Optionally, append msec or usec to specify a timeout in milliseconds or microseconds, respectively. Specifying a timeout considerably smaller than the packet round-trip time will produce unexpected results. AUTHORS
