Just recently dusted off my Ubuntu laptop and updated it to Hardy Heron (8.04). After doing so, however, I find I cannot connect to my WPA network.

The WNIC can see the access point and tries to connect to it, but all I get is a "Waiting for Network Key" message. After several minutes, I revert back to wired.

This tells me that the WNIC is functioning. I just need to get wpa_supplicant running again and I don't know how.

Where do I start working this issue?

Thanks in advance,
