Dell missing available wireless networks

Hi

I have just installed xp pro on my dell latitude d600 laptop. I cannot see the 'view available wireless networks' option anywhere. The drivers for the wirless network have not yet been installed.

Can somebody tell me what driver I need exactly and where to get it from. I believe the network card is a Broadcom BCM94309MP thats what i read when i opened the panel.

I was told I needed the intel pro 2200BG driver from this link but not sure if its true as it doesnt seem to work. I also dont see the Broadcom adapter in my device manager anywhere:

Please advise what to do.

Many thanks
