Help! "Packet Scheduler Miniport #8" Driver Error

Last night while trying to install a device, my notebook system locked up and I had to power it down manually. Nothing else would do it.

Since then, I show the error (in the subject, above) in the device manager under networking devices, which explains itself as unable to install the driver. The device, "Packet Scheduler Miniport #8," cannot be uninstalled. Now my internal wireless device will not communicate properly.

I've Googled this and apparently it's a reasonably common problem without any answers I can find. I've uninstalled the related devices and then reinstalled them, but it makes no difference.

One somewhat related post I found said this had to be dealt with in the registry somehow.

Any thoughts? Thanks for any help!
