won't detect wireless network but says there are available network

I have had my media centre pc connected to a wireless network for about a
year with no problem and now it will no longer detect any networks via the XP
connection method. I have recently installed SP3 but couldn't say if it was
straight after that I had the problem or not. I did a system restore but it
still doesn't work. The strange thing is that the networks are detected via
PC-Cillian Transaction Protector and via the software that came with the
wireless card (D-Link DWA-556) network card. It also pops up with the yellow
window that says "wireless networks detected, right click for more
infromation" but when I click on find available wireless networks it won't
detect any. A lap top in the same location detects about 7.

Any ideas? Any help would be appreciated.
Thanks

It could be XP SP3 issue. Try to remove it and reinstall it with safe mode.
Or this search result may help.

Also, IIRC, the XP Media Center software uses a slightly different method
to detect wi-fi adapters, and is pickier than the WZC GUI or vendor
utilities.

Below is a simple vbscript that I wrote to diagnose this problem, it
uses same method as Media Center,
if it won't show any adapters, then you have the same issue,
and only the wi-fi adapter vendor can fix it.

(the news reader may wrap long lines. If you can't make it run,
please email me and I'll send you it zipped. Remove NO from my addr)

Thanks,
I contacted the manufacturer and they haved have a new driver for SP3. I
did install it but windows wouldn't start up with that driver.....caused me
all kinds of headaches had to do a reinsall from scratch. As is it is just
my media centre PC I think I will just stick to SP2 as SP3 also appears to
cause media centre issues as well!
