Useless Vista diagnoses messages

[andrew247]

I recently built a new computer, and I decided to take the plunge and go for Vista.
However, I keep on having problems with my internet adaptor - it disconnects alot. This I can handle, since I can easily reconnect it.
What annoys me is what Windows tells me if I click "Diagnose" after it disconnects. It gives me a different answer nearly every time I reclick it. It seems to cycle through these messages:

This may be due to timeout or user interaction

Unknown reason

The network security key is incorrect

This last one annoys me, because I know the key is correct, and if I keep hitting connect, it will eventually connect, so the security key is right. I don't see why it has to change it's answer everytime I try to diagnose the problem. I appreciate it must be hard to make a program that diagnoses something that isn't working, but I would much rather it gave me a definitive answer rather than cycle through a number of different ones.

Anyone else have any issues like this?
