If your Intel WiFi 5100 series WiFi driver broke down after latest update in Ubuntu 10.04 LTS desktop, understand that you are not the only one here with the same problem. A good friend of mine had the exact same issue. This is what you need to do to solve 'WiFi driver breaks after update' issue in Ubuntu 10.04 LTS.
Disclaimer: I haven't tried and tested the below steps all by myself. I don't use Ubuntu 10.04 LTS anymore and hence can't reproduce the same problem. Use it at your own risk.
