I upgraded to Hardy over the weekend while I was sick. For the most part it was pretty uneventful. I use the Ubuntu variant on my school notebook, so I knew about the changes, but there doesn’t seem to be as much a difference in the Kubuntu variant. I just like the packages being up-to-date.
I installed the new KDE 4.0.4 and resolved to use it for about a week. I noticed the network was extremely slow. I thought maybe it was a problem with the desktop environment, as I hadn’t noticed it after the upgrade and before switching to KDE4.

Then I found this bug, affecting rt2500pci cards like my Linksys WMP54G. The card is incorrectly set to a 1M rate, instead of 54M. A simple $ sudo iwconfig wlan0 rate 54M sets it right again.
