Dell Inspiron 1545 Broadcom Wireless Drivers with Ubuntu Natty

If you can't connect with your Dell Inspiron 1545 on Ubuntu 11.04 beta 1 (Natty Narwhal), forget the threads such as http://ubuntuforums.org/showthread.php?t=1061710 unless you are planning on getting eye surgery very soon. (Don't get me wrong, it's very useful, but confusing and painful on a Friday night.)

Some background here: Every 6 months, I reinstall Ubuntu or upgrade from an existing version to the next on my dell inspiron 1545 laptop, and every time, I spend several hours troubleshooting my wireless card. (Always fun on Friday night!) As soon as it works, I just go on with my emails and various chores, forgetting to note whatever happened and how I -- or whoever -- fixed the issue. Too bad, in 6 months from now, I'm pretty sure I'll have to re-read the pile of posts about it all over again, and install packages that will ultimately make things worse before I find the solution... Well, let's try to make a short note this time.

    sudo apt-get remove --purge bcmwl-sta-common bcmwl-kernel-source b43-fwcutter

After a reboot:

    sudo apt-get install bcmwl bcmwl-sta-kernel-source b43-fwcutter

Open the "Additional Drivers" app:

    sudo jockey-gtk

If the Broadcom STA Wireless Driver Proprietary driver isn't enabled yet, please do so. Reboot and the wireless card should be enabled. If it doesn't work for you, please write a comment ... at: http://ubuntuforums.org/showthread.php?t=1061710
