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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1785171 Title: Intel I219-V Ethernet Interface on Ubuntu Linux Using e1000e Driver keeps Dropping Internet Connection Status in linux package in Ubuntu: Incomplete Status in linux source package in Bionic: Incomplete Bug description: I've turned up many, many new server and workstation systems over the years on both Linux and Windows. Never seen anything like this behaviour I'm witnessing on Ubuntu Server 18.04 before where I simply lose Internet connectivity while using a browser. Ethernet interfaces usually either work or they don't work. I've configured the Intel I219-V Ethernet interface (wired Ethernet connection, there is no wifi on this system) using the e1000e driver for Ubuntu. The Ethernet connection is configured to use NetworkManager via Netplan on Ubuntu 18.04 LTS Server version. ASRock Z370m Pro4 motherboard. The Ethernet interface will drop the Internet connectivity when I'm using either the Firefox or Chrome browser. It usually happens when I'm using the search features of the browser. I can't figure out what would cause this type of behaviour. When the Internet connection drops, the only way to get back Internet connectivity is to disconnect the wired connection using the Ubuntu features and then re-connect (this restarts the NetworkManager service I notice). In the NetworkManager logs I do notice an "auth" error about a file or directory not found. I've never seen that before. Note: The auth error does not coincide with the loss of Internet connectivity, but it does proceed it. Often there can be many hours between the auth error and the actual loss of Internet connectivity. After I reconnect the connection (via re-starting the NetworkManager service) all will be fine for up to a day or so, but then I stress test it with a bunch of searches using the browser and usually I can get the Internet connectivity to drop again. Repeat the disconnect and reconnect process again (aka re-start NetworkManager) and the Internet connectivity will be fine again. The longest I've seen it go without an "Internet connectivity drop" issue is about 36 hours. I notice that the e1000e driver does not list the I219-V as a supported Ethernet interface in the Intel documentation for the Linux version of the driver. I'm not sure why that is. The I219-V is supposed to used another driver, but it's not clear there's a Linux version for of the driver for the I219-V. I'm really disappointed that I've run into this issue with Ubuntu Server LTS 18.04 on this motherboard. I had CentOS Server 7.4 (my standard server OS, a great Linux distro) on this same motherboard for a week with no issues, so I know the motherboard and the I219-V Ethernet interface are 100% good hardware wise and can work properly. CentOS 7.4 uses NetworkManager as the default for managing the Ethernet interface. The only reason I'm using Ubuntu Server 18.04 on this motherboard is because of a specific package that Ubuntu has a newer packaged version than CentOS. CentOS is extremely stable when it comes to basic server functionality. Hopefully, this bug with the I219-V Ethernet interface using the e1000e drive for Linux can be verified and a fix rolled out.
