Acer 4050 can no longer detect wireless networks

Suddenly my Acer 4050(XP home) can no longer detect wireless networks.
Worked fine until one week ago, but I have tested at various locations
with several wireless networks: No networks detected!

Have to mention that the switch for wireless connectivity is turned on!

Any ideas on how to remedy this problem?

What type and model is your wireless card?
Are you using XP to manage the wireless card or a proprietary manager?
Have you recently changed any settings?
Have you tried fitting another card and trying that?

The wireless card is as far as I know build into the motherboard
(Centrino), so no separate card is inserted

I'm using XP's build in wireless manager

To the best of my knowledge no. But these days with a daily flood of
Virus and operating system security updates I'm not 100% sure about this
;-)
One thing that I have tried to look into is any possible missing
services (Control Panel > Administrative Tools > Services). I have not
changed the services settings, but when searching for solutions to this
problem I noticed a few people where the "Wireless Zero Configuration"
for some reason was not started. I have not been able to locate this
service at all in my services list, however this might be explained by
that this service is named different in my Danish languaged XP. However,
having scanned through all services, I cannot find anyone that comes
near this name. If this service could be missing, how could I then add
it to services?

I do not have access to other cards, but will try to see if I can borrow
one this evening, and then I will come back with a reply to how this reacts.

Thanks for your help so far!

There seem to another problem on the computer that I have not been aware
of before. For the first time ever I tried to insert a PCMCIA card
(Trendnet Wireless 125 Mbps 802.11g wireless PC card), and the computer
didn't recognize it at all. Using the Install hardward wizard shows
these two problems:
!: Intel PCIC compatible PCMCIA-controller
!?: Network controller

When connected to the internet via cable, and selecting these two
drivers, the automatic installation fails. I assume that the network
controller should have been part of the configuration when the notebook
was delivered, so I need somehow to find a way to get the above two
drivers to work. But a little lost on how to do this when the automatic
configuration fails :-( The error was described as the wizard being
unable to locate the correct software (choosing automatic installation).

Whether this problem has occurred in connection to the problem with the
missing detection I don't know, neither if this problem was already
there when I bought the notebook 10 months ago.

Any good ideas would be much appreciated!

Since you are using XP have you tried to "Restore" it to a point in time
prior to you having a problem?
On my XP home Laptop start>help and support then "undo changes to your
computer with System Restore" in "Pick a Task"

Thanks a million Rob! I was totally unaware of this function, but that
did the trick. So now I can detect wifi's again :-))
