** Description changed: At school when I connect with my Ethernet cable to its network it doesn't see my cable, like it is disconnected. This occurs with a different computer using the same kernel driver with the same LAN chip. The realtek r8168 works flawlessly but it disconnects randomly. I don't have problems in Windows (speed is 100Mbps), or with other computers using the same cable. WORKAROUND: ethtool -s enp1s0f1 autoneg off speed 100 duplex full + + WORKAROUND: Add kernel parameter: + acpi_rev_override --- ApportVersion: 2.19.1-0ubuntu5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: luky 1556 F.... pulseaudio /dev/snd/controlC0: luky 1556 F.... pulseaudio CurrentDesktop: X-Cinnamon DistroRelease: Ubuntu 15.10 InstallationDate: Installed on 2016-02-12 (6 days ago) InstallationMedia: Ubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) MachineType: Acer Aspire E5-571G Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.2.0-29-generic.efi.signed root=UUID=211171d7-1b39-4c4b-8078-7ccbdd97ffdc ro quiet acpi_osi= acpi=force acpi_enforce_resources=lax i915.enable_rc6=1 i915.enable_fbc=1 i915.lvds_downclock=1 i915.semaphores=1 drm.vblankoffdelay=1 acpi_backlight=vendor ProcVersionSignature: Ubuntu 4.2.0-29.34-generic 4.2.8-ckt3 RelatedPackageVersions: linux-restricted-modules-4.2.0-29-generic N/A linux-backports-modules-4.2.0-29-generic N/A linux-firmware 1.149.3 Tags: wily UdevLog: Error: [Errno 2] File o directory non esistente: '/var/log/udev' Uname: Linux 4.2.0-29-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm bumblebee cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 08/03/2015 dmi.bios.vendor: Insyde Corp. dmi.bios.version: V1.31 dmi.board.asset.tag: Type2 - Board Asset Tag dmi.board.name: EA50_HB dmi.board.vendor: Acer dmi.board.version: V1.31 dmi.chassis.asset.tag: Chassis Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: Acer dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnInsydeCorp.:bvrV1.31:bd08/03/2015:svnAcer:pnAspireE5-571G:pvrV1.31:rvnAcer:rnEA50_HB:rvrV1.31:cvnAcer:ct10:cvrChassisVersion: dmi.product.name: Aspire E5-571G dmi.product.version: V1.31 dmi.sys.vendor: Acer
