[Bug 991232] Re: Regression in wireless performance when on battery power (broadcom)
On my newish Acer AS5750 I enabled ACPI so that I could enable screen dimming (since it wasn't working as expected). Then once unplugged from the wall socket Wifi latency increased and then quit completely after approx. one minute (BCM43227). Makes portability pretty useless!! Luckily I found the following blog post: http://uselessuseofcat.com/?p=67 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991232 Title: 14e4:432b Regression in wireless performance when on battery power To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/991232/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Bart Heinsius, thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read How to report bugs effectively http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem. We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures At a minimum, we need: 1. the specific steps or actions you took that caused you to encounter the problem, 2. the behavior you expected, and 3. the behavior you actually encountered (in as much detail as possible).

Bart Heinsius, please execute the following command, as it will automatically gather debugging information, in a terminal: apport-collect 991232 As well, 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.
