[LIH] wifi not working

hi!

I have a compaq presario C797VU, with Ubuntu 8.04 desktop on it. I had managed to get wpa-suppliant working on it. But since today morning I am not able to get my wifi on.

iwconfig gives me the following output.
lo        no wireless extensions.

eth0      no wireless extensions.

Please suggest what do i do?

Thanks
