[Sheflug] Configuring Wireless connection on a laptop

[Peter Collier <pecb@xxxxxxxxxxxxx>]

I am attempting to convert someone to linux. All very well except I'm not sat 
in front of his laptop and I'm doing it by phone. So far I've managed to get 
him to install Xubuntu. 

(it's an old IBM Thinkpad and Kubuntu install struggles:-memory/cpu etc).

 I've managed to get him to configure his wireless pcmcia card via ndiswrapper 
and drivers load ok on reboot. All this was extremely difficult. Dealing with 
someone to whom the concept of installing was alien, never heard of doing 
this, never used a dos prompt and getting comments like why can't I just 
click somewhere. 
	Where I am stuck, despite much googling around, is how to get his wireless 
card to communicate with his router. 
	Using "sudo iwlist wlan0 scan" in a terminal, he gets the following main 
lines:-

CELL 01 ADDRESS 00:09:F3:70:C4:AD
ESSID T1
PROTOCOL IEEE 802.11b
Mode Advanced
Encryption Key OFF

In the following commands, what do I put where?

sudo iwconfig wlan0 essid name_of_AP

iwconfig wlan0 enc <key>  (I assume this is not used at this stage because no 
encryption at the router is as yet configured.)

Any help appreciated as this is my first attempt at wireless.
