[Kernel-packages] [Bug 1249008] Re: iwlwifi kernel driver does not obey power saving settings
If you're using TLP http://linrunner.de/en/tlp/tlp.html then you can disable power management when on battery by changing the option WIFI_PWR_ON_BAT=5 to WIFI_PWR_ON_BAT=1 about halfway down in the file /etc/default/tlp. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1249008 Title: iwlwifi kernel driver does not obey power saving settings Status in “linux” package in Ubuntu: Expired Bug description: Poor ping times (high latency) can be observed after unplugging from a power source.

[Kernel-packages] [Bug 1249008] Re: iwlwifi kernel driver does not obey power saving settings
Maybe this is the intended method for this? The best fix for the horrid performance this causes is to create a file in /etc/pm/power.d/ containing the iwconfig wlan0 power off command. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1249008 Title: iwlwifi kernel driver does not obey power saving settings Status in “linux” package in Ubuntu: New Bug description: Poor ping times (high latency) can be observed after unplugging from a power source.

[Kernel-packages] [Bug 1249008] Re: iwlwifi kernel driver does not obey power saving settings
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 kernel[0]. 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'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.
