The worst day of my computing life (so far)

Archived from groups: microsoft.public.windows.networking.wireless (More info?)

After 4 days I am no further forward
What is it with XP SP2 that doesn't allow a wireless connection to other
devices via a wireless router/default gateway?

Situation :
Host PC - Connected to ADSL via ethernet cable direct to BT voyager 2000
ADSL Router = connection to internet

PB E5 Easynote notebook with built in WiFi cannot connect at all, cannot
even recognise router, (it did before SP2)

Client PC with Netgear MA111 USB wireless adapter running xpsp2 not a hope,
(worked well before sp2)

What a cock up
