IMAP, SSL, Outlook XP and dropping connections

Hi,

I have the following problem which I can't see to solve, if anyone has
any bright ideas I'd be grateful!

Toshiba Tecra 9100 / Toshiba Wireless LAN Mini PCI Card / Agere Systems
driver v7.42.0.300
Netgear ME102

I have the ability to check my email via IMAP & SSL. If I turn this on
in Outlook XP and check my mail my wireless connection drops. The same
if I attempt to run NMap over wireless, but none of this appears should
I use a wired lan connection.

Nothing else exhibits this problem. I've got the latest drivers for the
wireless chipset I can find, which are dated 19/12/2001, Toshiba BIOS is
updated to it's latest revision, as is the ME102 firmware but it still
happens.

If anyone has a solution I'd love to know!

Thanks
