Ubuntu 8.04 Wireless Woes

I just finished updating my laptop from Ubuntu 7.10 to the new Ubuntu 8.04 release.  All went well except for one thing.  In addition to many other improvements, Ubuntu 8.04 installed a new version (2.6.24-16) of the Linux kernel.  Now this would seem to be a good thing.  But, once again a Linux distribution failed my "Ready for Prime Time" test...which is to provide me with a working 802.11b/g, or "Wi-Fi," interface with little or no pain my part.
