Public bug reported: I have a Thinkpad T520 and a W520, both with the same ethernet device, Intel 82579LM.
Running under Windows, speedtest reports ~1Gb up & down, so the hardware is good. Under Ubuntu 18.04, kernel 4.15.0-50, I get ~1Gb down but only ~4Mb (!) up. e1000e is version 3.2.6-K and e1000 is version 7.3.21-k8-NAPI. Note that I also have a Thinkpad T530 with those same versions of driver, and it gives me ~1Gb in both directions. I have tried a number of attempted solutions which have had no effect: ethtool -K eth0 gso off gro off tso off ethtool -K eth0 tx off rx off ethtool -G eth0 tx 256 rx 256 ethtool -G eth0 tx 8096 rx 8096 Turning off ASPM in BIOS and via the kernel parameter pcie_aspm=off Note that I also have a Dell Optiplex 980 with an 82578DM running CentOS wich had the same problem (4Mb up). Turning off ASPM in BIOS corrected the issue there. I also note that there is another issue with this driver that was never resolved: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1766377 Finally, I tried to install the most recent version of this e1000 and e1000e, but they do not compile under Ubuntu 18.04: https://sourceforge.net/p/e1000/bugs/643/ --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.6 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: dev 2052 F.... pulseaudio CurrentDesktop: MATE DistroRelease: Ubuntu 18.04 HibernationDevice: RESUME=UUID=7c310224-1fd2-472b-91a8-2d3f3001642c InstallationDate: Installed on 2018-08-31 (264 days ago) InstallationMedia: Ubuntu-MATE 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) MachineType: LENOVO 4284A94 Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/@/boot/vmlinuz-4.15.0-50-generic root=UUID=36d8a469-5f40-46de-887d-90fbd0b4aa3b ro rootflags=subvol=@ quiet splash vt.handoff=1 ProcVersionSignature: hostname 4.15.0-50.54-generic 4.15.18 RelatedPackageVersions: linux-restricted-modules-4.15.0-50-generic N/A linux-backports-modules-4.15.0-50-generic N/A linux-firmware 1.173.6 Tags: bionic Uname: Linux 4.15.0-50-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom debian-tor dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 10/20/2016 dmi.bios.vendor: LENOVO dmi.bios.version: 8BET63WW (1.43 ) dmi.board.asset.tag: Not Available dmi.board.name: 4284A94 dmi.board.vendor: LENOVO dmi.board.version: Not Available dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvr8BET63WW(1.43):bd10/20/2016:svnLENOVO:pn4284A94:pvrThinkPadW520:rvnLENOVO:rn4284A94:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.family: ThinkPad W520 dmi.product.name: 4284A94 dmi.product.version: ThinkPad W520 dmi.sys.vendor: LENOVO ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete ** Tags: apport-collected bionic driver e1000 intel -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1830197 Title: e1000e driver - uploading slowed to a crawl.
