Ubuntu 9.10 has recently been released and if you haven’t tried it yet, go check it out. However, you may be one of the people who has upgraded from 9.04 to 9.10. Everything worked fine, except the wireless Broadcom network card in your machine just doesn’t auto-start anymore.

A fix would be to access System -> Administration -> Hardware Drivers. Here, you can remove and the re-activate the proprietary Broadcom STA driver to make your wireless network card work in Ubuntu 9.10. The downfall is that you’d have to perform this task on each startup.

But in order to permanently make it work, you must access System -> Administration -> Synaptic Package Manager. Then you reload the list and search for:

bcmwl-kernel-source

Now, right-click on the package name and choose “Mark for Reinstallation”. Then press the big, green “Apply” button, wait till it’s done, restart, and you’re good to go!
