[Kernel-packages] [Bug 1785171] Re: Intel I219-V Ethernet Interface on Ubuntu Linux Using e1000e Driver keeps Dropping Internet Connection
Some update comments on the issue with the Ubuntu 18.04 network connectivity that started as soon as I installed Ubuntu Server 18.04 with the motherboard using this Intel i219-v network adapter. The issue is getting worse, not better. Previously the "drop" of the network connection with Ubuntu Server 18.04 would occur every 2 or 3 days. But now the drops are occurring multiple times daily. I don't even need to be using/doing anything on the machine anymore. The network connection will be fine once second and then down a minute later. The only way to get it back is to "disconnect" manually (in the Ubuntu software setting for the adapter) and then reconnect manually. No dual boot system, etc. It's a plain as can be Linux server that right now is not of much use because the network connectivity (something that should be 100% stable) keeps cutting out. -- 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: Confirmed Status in linux source package in Bionic: Confirmed Bug description: I've turned up many, many new server and workstation systems over the years on both Linux and Windows.

Can someone please let me know what further is needed, or simply say there's nothing that can be done to fix the issue with Ubuntu 18.04 server.

[Kernel-packages] [Bug 1785171] Re: Intel I219-V Ethernet Interface on Ubuntu Linux Using e1000e Driver keeps Dropping Internet Connection
The loss of the Internet connectivity on Ubuntu Server 18.04- continues to be an issue with the Intel i219-v onboard Ethernet adapter. I just lost the Internet connectivity on the Ubuntu 18.04 server and I was not even doing anything on the server. I just logged in and the Internet connectivity had dropped. There's no way this should be happening if the OS/driver software was driving the Ethernet adaptor properly. I've run several experiments over the last few weeks on the performance and stability with both the NetworkManager and networkd services. I was thinking that maybe the networkd implementation by Ubuntu Server was stable, but that's was a no go as well. Same behaviour as with NetworkManager. I'm going to have to remove Ubuntu Server 18.04 (probably go back to CentOS Server 7.4) if Ubuntu Server 18.04 can't manage the required networking. Simply should not be an issue given the long-term proven technologies involved with Ethernet and IP networking.

[Kernel-packages] [Bug 1785171] Re: Intel I219-V Ethernet Interface on Ubuntu Linux Using e1000e Driver keeps Dropping Internet Connection
Obviously, there's others having issues with Ubuntu Server 18.04 and their network connectivity. I prefer to use NetworkManager to control my wifi and wired Ethernet network interfaces. Ubuntu has a different view it seems (prefer networkd for wired interface, NetworkManager for wifi it seems), but there should be no bugs for those that choose to configure their systems to use NetworkManager. My networking hardware with NetworkManager is rock solid on CentOS Server 7.4, so I don't get why the network connectivity using NetworkManager is not stable for Ubuntu Server 18.04? Please see the following string from this recent Ubuntu bug ticket opened with regards to the wired network interface not working properly with Ubuntu 18.04 (their is is mostly similar, though their road is slightly different in figuring out something is not right with Ubuntu 18.04 server and their network interface). To sum this long bug post, the Ubuntu Server 18.04 implementation of NetworkManager is maybe not preferred, but it should be working perfectly on my Intel i219-v onboard network adapter. https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1772859 There's a bug somewhere (e1000e driver, Ubuntu 18.04 implementation of NetworkManager, etc.) given the poor/strange performance I'm seeing on multiple fronts. Intermittent loss of internet connectivity and very, very poor download performance across my setup of the Intel i219-V onboard NI and the implementation of Netplan/NetworkManager on the Ubuntu Server 18.04 OS. If it's not a bug (meaning a configuration like mine is proven 99.% stable using the scientific method through verification in the lab), then let's get the proper NetworkManager configuration information documented in detail on the Ubuntu wiki, so this same issue is not be brought up over and over again.

Thanks for the reply. Maybe I'm not correctly interpreting the reply referring to "a kernel issue like this requires kernel bisection" and "We can't do much if we don't have the hardware". Why would the internet connectivity issues I'm seeing with Ubuntu 18.04 Server running the Intel onboard i219-v Ethernet adapter be a kernel issue? As I've stated multiple times already, this i219-v Ethernet adapter ran perfectly on CentOS Server 7.4 for over a week (and we know CentOS is much more conservation with the Linux kernels used in their distribution) before I removed CentOS 7.4 and decided I'd given Ubuntu Server 18.04 a try and see where Ubuntu is at as a Linux server distribution vs CentOS. Given my experience designing and building $B networks, this is not a hardware issue (very, very rare) and given CentOS Server 7.4 worked perfectly for everything expected of a server, including the network performance using this same i219-v Ethernet adaptor, it's most likely not a Linux kernel issue. There's something in the way Ubuntu Server 18.04 is configured to use this Intel i219-v onboard network adaptor hardware that's the root of the issue. It's probably a scenario that Ubuntu Server 18.04 had probably not seen before and was never verified with (given what I know and have observed with how software is tested these days. My vendors constantly use us as a testing platform, but that's a separate story). Again today, the network adaptor on the Ubuntu 18.04 server lost connectivity to the internet and I had to disconnect and then reconnect the wired Ethernet connnection to get the internet connection backup (simply, Network Manager service has to be stopped and then restarted, you can see it clearly in the logs I provided in a previous post). What is Ubuntu support/development saying here? That Ubuntu Server 18.04 can't execute basic internet connectivity on the i219-v Ethernet adaptor in a 100% stable manner? -- 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.

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?

Thanks for the replies. The "Internet dropping" issue started as soon as I installed this complete new Ubuntu Server 18.04 on the ASRock z370m Pro4 motherboard. Then added the GNOME Desktop, and had to change the Ethernet network configuration to use Netplan and NetworkManager service. Note: I know the motherboard and the I219-V network interface work perfectly as the same new motherboard ran CentOS Server 7.4 (minimal) with an XFCE Desktop flawlessly for over a week. CentOS 7.4 uses NetworkManager service by default (unlike Ubuntu Server which does things very different than CentOS Server for the network connection. I only decided to try Ubuntu Server 18.04 to gain access to a package that had a newer version than CentOS Server had (CentOS focuses on stability over features and it shows). I can't use the upstream Ubuntu kernel for fear too much of my server setup (Nvidia graphics, etc) will break. I've already seen bugs in the Nvidia graphics driver from the Ubuntu PPA (a separate issue), so I don't want to add more issues to this Ubuntu server setup.
