TCP/IP installation issue

Specs: Windows XP Pro
Hi,

I'm running Windows XP Pro SP3 but whenever I attempt to install TCP/IP protocol in order to get connected to a central wireless network via an access point (I have a SSID key)* I keep getting the message : "Could not add the requested component. The error is: The data is invalid"

Weirdly I'm able to get connected with the same credentials via another machine from the same location, which runs Windows Vista Home Basic, but not via the other machine, which until recently was working fine with an ethernet connection though and, in the past has worked just as good as part of a small home wireless network.

Can anybody suggest how I could get my head around this?
Thanks

* The wireless network I set up via the wizard is not even visible in "My network connections" window

I believe there are some hot fixes after 3

what happens if you do an ipconfig /all via cmd prompt? Does it work? Can you post it for review?

is the nic connected to the router via a patch cable? Lights on at both ends?
I thought you were doing wireless?

it would be helpful if you posted the entire ipconfig /all

Let me ckarify this: I'm not the administrator of the wireless network; its administrator and the central computer is located 2 floors below mine...so no routers or ethernet cables involved in my flat...in fact, my other machine with windows vista has no problem accessing the same wireless network.

The entire ip config window in cmd reads as follows:

Microsoft Windows XP [Version 5.1.2600]

C:\Documents and Settings\home>ipconfig

Windows IP Configuration

Media State . . . . . . . . . . . : Media disconnected

Your ipconfig /all only shows the wired nic which isn't connected to anything.

So if you go to network what do you have listed here? Lan and wireless or only lan?

Ok in the network connections window I got listed only a LAN connection, no wireless.

You're absolutely right about the ipconfig data, just didn't realise I had to add "all" after "ipconfig". So here's the entire ip config /all window in cmd:

Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\home>ipconfig /all

WINS Proxy Enabled. . . . . . . . : No

Ethernet adapter Local Area Connection:
