I found the instructions for creating and running the startup script in: and then I tailored them for my own use. Once it reboots, the wired connection should be active. Next enable the service unit: $ sudo systemctl daemon-reload $ sudo chmod 664 /etc/systemd/system/rvice Set appropriate permissions for both, the Systemd service unit and script: $ sudo chmod 744 /usr/local/bin/start-ethernet.sh ![]() The below is an example of such script: #!/bin/bashĮthtool -s ens5f5 autoneg on speed 100 duplex full Anyway, the Ethernet cable seems to be fine, as I plugged it in to my laptop and it connect without a problem, so I assume this is a problem on the computer, specifically with the network driver, which says 'network cable unplugged' on the control panel, and when I run a diagnostic to try and troubleshoot it says the cable is ' not properly. One of the primary design goals of the TCP protocol is that temporary interruptions in network connectivity don't break connections. This is one of Microsoft's most foolish design decisions. As specified in the above Step 1, the path and the name of the new script is /usr/local/bin/start-ethernet.sh. At least in XP, unplugging your NIC should set its state to 'disconnected' not 'disabled'. WantedBy: Into what boot target the systemd unit should be installedĬreate a script to be executed on Ubuntu system startup. Other example could be mysql.target etc.ĮxecStart: This field provides a full path to the actual script to be executed on startup In our case the script will run after network connection. ![]() I then created a script to run on startup so I wouldn't have to run the command every time the computer booted up.įirst, create a Systemd service file as in an example below (the file I created was /etc/systemd/system/rvice): ĮxecStart=/usr/local/bin/start-ethernet.shĪfter: Instructs systemd on when the script should be run. I changed autoneg from off to on so I am not sure if that helped or if it was the fresh install of Ubuntu or a combination of the two, but I'll take it. I was able to achieve an acceptable speed from a speed test (a download speed of 93.45). After re-installing Ubuntu 22.04 and then running: sudo ethtool -s ens5f5 autoneg on speed 100 duplex full
