Help Unable to Connect to Wifi?

[phenixdragon]

Today, I was connected to my wifi at home with my Nexus One. I had to reboot my router, and all of a sudden, the Nexus One doesn't connect to my wifi. When I tell it to, it just says Connection unsuccessful, touch to try again. I tried reboot my phone and router again and also deleting the connection and connecting again, and nothing. It doesn't connect.

Any ideas?

So I went in and disable the security on my router, phone connected right up. I then enabled the security, phone connected right up. Weird.
