Roman Vasilchenko, thank you for reporting this and helping make Ubuntu better. As per http://us.acer.com/ac/en/US/content/drivers an update to your computer's buggy and outdated BIOS is available (1.25). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-1.25 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** 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/1500140 Title: acer-e5-573g-wi-fi-adapter-not-working Status in linux package in Ubuntu: Incomplete Bug description: http://askubuntu.com/questions/674662/acer-e5-573g-wi-fi-adapter-not- working uname -a Linux 573g 3.19.0-28-generic #30-Ubuntu SMP Mon Aug 31 15:52:51 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: linux-image-3.19.0-28-generic 3.19.0-28.30 ProcVersionSignature: Ubuntu 3.19.0-28.30-generic 3.19.8-ckt5 Uname: Linux 3.19.0-28-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 2.17.2-0ubuntu1.4 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: roman 1953 F.... pulseaudio /dev/snd/controlC0: roman 1953 F.... pulseaudio CurrentDesktop: Unity Date: Sun Sep 27 08:26:38 2015 HibernationDevice: RESUME=UUID=29811a9c-29cf-4739-a3a5-7ddc15d428e0 InstallationDate: Installed on 2015-09-19 (7 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Release amd64 (20150422) IwConfig: eth0 no wireless extensions. lo no wireless extensions.
