Comment 18 for bug 216634

Unfortunately it seems this bug is still an issue. Can you confirm this issue exists with the most recent Jaunty Jackalope 9.04 release - http://www.ubuntu.com/news/ubuntu-9.04-desktop .

Also, Can you please try installing the linux-backports-modules-jaunty package. The linux-backports-modules-jaunty package contains and updated compat-wireless stack which may help. Be sure to reboot after installing this package in order to test. Please let us know your results.

If the issue remains even after installing and testing linux-backports-modules-jaunty, could you then please try the latest upstream compat-wireless stack. See http://wireless.kernel.org/en/users/Download for more info. If the issue exists upstream, we'll want to work with the upstream developers to try to get this resolved. Also, after confirming the issue remains with the latest upstream compat-wireless stack, be sure to also run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux-image-2.6.28-11-generic 216634

Please let us know your results. Thanks.
