Some more notes on Ubuntu 18.04 and Intel i219-v onboard wired ethernet interface performance.
The same problematic patterns continue with the dropping of the Internet connectivity through normal browser use (Chrome is more stable than Firefox). I have to disable and then re-enable the wired Ethernet interface, and then I can resume network activities again until the next connectivity drop. I have multiple servers/work stations and multiple high speed Internet accesses to verify this new Ubuntu server's performance (commercial grade network and servers/work stations...I built them myself) and they (networking and Internet connectivity) are all 100% stable. Keep in mind, I ran this same i219-v Ethernet interface under CentOS Server 7.4 for over a week (before converting the server to Ubuntu Server 18.04) and the network and Internet connectivity were 100% perfect on CentOS 7.4 with an Xfce desktop. I did some more performance tests on this problematic Ubuntu 18.04 server and the i219-v performance. I noticed the wired download speed on the Ubuntu 18.04 server via the i219-v NIC is half what it should be (verified by all the other computers on the network). The Ubuntu 18.04 server does not come close to matching the download speed on my high end laptop using the wifi. The wired upload speed on the i219-v on the Ubuntu 18.04 server is OK though. This confirms to me that something is definitely not right with the new Ubuntu 18.04 server running this i219-v onboard NIC. My review of similar reported issues with the i219-v on Linux (granted, on various Linux distributions, not necessarily Ubuntu) seem to indicate that some have resorted to using the Intel e1000e driver directly from the Intel site versus from the driver from the distribution. Note: The is not Linux driver from Intel that specific supports the i219-v. Seems people use the e1000e driver anyway as that's all there is. The e1000e driver specs do state the i218-v is supported. Here's the link to the Intel e1000e driver (for Linux) on the Intel site. https://downloadcenter.intel.com/download/15817/Intel-Network-Adapter-Driver-for-PCIe-Intel-Gigabit-Ethernet-Network-Connections-Under-Linux-?product=71305 My Ubuntu Server 18.04 server currently packages the e1000e driver version 3.2.6-k Intel's latest version of this Linux driver is version 3.4.0.2. Is there a package for this e1000e that Ubuntu has developed for the 18.04 distro based on 3.4.0.2 that can be installed so that I can test the performance of this version on my Ubuntu 18.04 server? (rather than me download it directly from Intel). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1785171 Title: Intel I219-V Ethernet Interface on Ubuntu Linux Using e1000e Driver keeps Dropping Internet Connection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1785171/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
