piovisqui, thank you for reporting this and helping make Ubuntu better. As a potential workaround, could you please try the compat-wireless backport kernel noted in https://launchpad.net/ubuntu/+source/linux-backports-modules-3.2.0 ? If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Please let us know your results. Thanks in advance. ** Description changed: My wlan network card does not work properly anymore. the connection stays online for only one minute. Then the networkmanager tries to reconnect. Sometimes it asks the password again. - - THIS BUG IS A BLOCKER! A PC without internet is good for what? - - Please, fix it. - - pio@piobox:~$ lspci -vvv -s 07:01.0 - 07:01.0 Network controller: Atheros Communications Inc.
