How do I connect my Windows-7 on my wireless router with a password?

This seems to be a fairly common problem. Three of my offspring have Windows 7 on their laptop. The same problem did crop up. The solution in each case was to let Windows 7 run, and try again. In each case connection was established in less than half an hour. It seems that the problem lies in the way Windows 7 manages the wireless and network adaptors. Since it worked in all three cases, I believe the method will also work for you.

Do you have the wireless key to your router? That's all it took for mine and mine is a secured network. It was easier with Windows 7 than it was with Vista and much easier than I anticipated.
