Comment 174 for bug 272185

First off - this bug is *not* invalid. Don't know why it is marked as such. At any rate I think I've got a simple solution. It's off the wall, but it works on a variety of chipsets (atheros, ipw2200...).

## WARNING: Following these instructions may break your Intrepid installation. They worked great for me on a variety of laptops, but your mileage may vary. Proceed at your own risk. ###

The problem is with how wpa_supplicant and network manager interact. Updating the relevant packages to their jaunty equivalents fixes the problem. Here's the procedure:

0. Run a standard update to make sure you have all relevant Intrepid updates.

1. Add the jaunty repositories to /etc/apt/sources.list. Using your favorite text editor (ex. gksudo gedit /etc/apt/sources.list), add the following lines (we will remove these when all is said and done.)
# Jaunty Sources
deb http://us.archive.ubuntu.com/ubuntu jaunty main restricted
deb-src http://us.archive.ubuntu.com/ubuntu jaunty main restricted

2. Update your sources list by running the following command: sudo apt-get update

** A zillion new updates will show up. Do not run any automatic updaters! Doing so may break your installation. **

3. Open the synaptic package manager (System --> Administration --> Synaptic Package Manager). Search for and upgrade the packages listed below:
* wpasupplicant
* libnm-glib0
* libnm-util0
* libxcb-render-util0
* network-manager
* network-manager-gnome

After you finish - Ubuntu will tell you to restart. Don't restart yet.

4. Go back and remove the lines from step one (1) from your /etc/apt/sources.list. Once the lines are removed -- save the file. After that, do another sudo apt-get update to remove the jaunty sources. Any automatic updaters should go back to normal and say that no updates are available.

5. Now restart your computer. It should all work after that. You may have to delete your existing (broken) associations in order for it to work right.

Tested to work on several atheros chipsets and several Intel chipsets. Special thanks to the College of William and Mary for providing the test equipment.

I hope it works out for you!
