Vista Updates Killed my Wireless Connection

[Guest]

After my very first download of Windows Updates on my new Advent Windows
Vista laptop, my wireless Internet connection (via a D-Link router), which
was working fine for weeks right up to that point, suddenly went offline and
is now nowhere to be found.

The network adaptor is switched on, but there is no connectivity at all.
When I click on Connect, I'm informed that Windows cannot find any networks.
When I run the diagnostic tool, I'm informed that it's because a cable is
unplugged. If I want to connect to the internet I am offered two choices -
dial-up or broadband, and no option to connect wirelessly.

On reboot, I'm getting two error messages:
1] The procedure entry point apsGetInterfaceCount could not be located in the
dynamic link library wlanapi.dll

2] The procedure entry point apsInitialize could not be in the dynamic link
library wlanapi.dll

I tried copying wlanapi from my System32 directory into the D-link directory
but this hasn't made any difference.

I would really appreciate any suggestions on how I can retrieve my former
network connectivity without having to reinstall Windows from scratch.

Thanks - everything seems to be back to normal and the wireless is indeed
working again.

What I'm a bit worried about, though, is what to do about the updates in
future. I've disabled Automatic Updates but it's already started to nag me
to reinstall the updates I just took off, and I'm not sure which of them
caused my wireless connection to disappear, or whether I'm putting my
computer at risk by not installing some of the others.
