Federico Sassi, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.
If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested exactly shown as: kernel-fixed-upstream-3.18-rc6 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags removed: bios-outdated-2.16 ** Tags added: latest-bios-2.16 ** Changed in: linux (Ubuntu) Importance: Low => Medium ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1397032 Title: [Lenovo ThinkPad T540p] Intel Wireless Dual Band 7260AC fails to connect Status in linux package in Ubuntu: Incomplete Bug description: I have a Lenovo Thinkpad T540p and the wireless connection isn't working correctly. It will list the available networks but when trying to connect it will keep asking for the password or when it connects the connection will last only few seconds and the packet loss on a ping will be very high. I've followed bug https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1354975 in order to find a solution but without luck. I've tried to turn off power management, install latest kernel ( linux-image-3.17.0-031700-generic ) and related updated firmware according to http://wireless.kernel.org/en/users/Drivers/iwlwifi . Tried also the updated firmware for the older kernel and with the older kernel. I've tried also Ubuntu 14.10 with same results. I've tried to move closer to the router but with no change at all.
