Can't access settings for client in wireless network

Client is XP Pro SP3. Router Linksys WRT54G. I an trying to access the
security and authentification settings. I can do it on my other
systems but using the usual method doesn't work, From MS:

1) Open Network Connections.

2) For a wireless connection, do the following:
Click the wireless connection, and then, under Network Tasks, click
Change settings of this connection. On the Wireless Networks tab,
click a wireless network in the list, and then click Properties.

And that's as far as I can get because "change settings of this
connection" isn't there.

Where did it go and how do I get it back?

Hi
