How can I set a static IP address for a USB RNDIS Ethernet device in Ubuntu? I’m looking for guidance on configuring this so that it consistently uses the same IP address for connectivity.

I’m running into a bit of a snag with my USB RNDIS Ethernet device on Ubuntu, and I could really use some help from anyone who might have tackled this before. So, here’s my situation: I sometimes use this USB Ethernet dongle when connecting to my router, and I need it to have a static IP address so I don’t have to keep messing around with settings every time I plug it in. It’s super annoying when I have to look up the new IP each time, especially for some network configurations I’m working on.

I’ve tried a bunch of different things, but honestly, I’m getting a bit overwhelmed by the various methods I’ve found online. I know I should be able to set a static IP either through the Network Manager or by editing some configuration files, but I’m not entirely sure which route to take—or if there’s a better method altogether. Plus, I’m a bit worried about messing up the existing configurations, as my general setup works fine, aside from the dynamic IP part.

If anyone could give me a step-by-step guide or share their experience on how to do this, I’d really appreciate it. Specifically, I’d love to know which files I need to edit or if there are command-line settings I need to be aware of. And don’t even get me started on the Network Manager—do I have to use that GUI, or can I set it up via terminal commands? Also, if there are any important things that I should keep in mind about my network settings while doing this, please share!

Any insight would be extremely helpful, as I really want this USB RNDIS device to work seamlessly without me having to check what new IP it’s picked up every time I plug it in. Thanks in advance for your help!

    1. Setting a Static IP for USB RNDIS Ethernet on Ubuntu

      Help with USB RNDIS Ethernet Device on Ubuntu

      It sounds like you’re really frustrated with the whole dynamic IP thing! I’ve been there, and setting a static IP for your USB Ethernet dongle can definitely save you a headache.

      Using Network Manager GUI

      If you’re okay with using the GUI, here’s a simple way to set a static IP:

      1. Click on the network icon in the top-right corner of your screen.
      2. Select “Settings” or “Network Settings”.
      3. Find your USB Ethernet connection in the list (it might be called something like “Wired” or similar).
      4. Click on the settings (gear) icon next to it.
      5. Go to the “IPv4” tab.
      6. Change the “Method” to “Manual”.
      7. Now, enter your desired IP address, Netmask (usually `255.255.255.0`), and Gateway (your router’s IP, commonly `192.168.1.1`).
      8. Hit “Apply” and reconnect your network.

      Using Terminal (if you prefer the command line)

      If you want to go the terminal route (totally understandable!), you can edit the Netplan configuration files:

      1. Open the terminal.
      2. Type: sudo nano /etc/netplan/01-netcfg.yaml (the name might vary, but it’s usually something like this).
      3. Look for the section that corresponds to your USB RNDIS device. It might look something like:
        4. network:
    version: 2
    renderer: NetworkManager
    ethernets:
        usb0:  # This might be your device
            dhcp4: true
      4. Change the `dhcp4: true` line to:
        5.             dhcp4: false
            addresses:
                - YOUR_STATIC_IP/24
            gateway4: YOUR_GATEWAY_IP
            nameservers:
                addresses:
                    - YOUR_DNS_SERVER
      5. Save the file and exit (CTRL + O, then ENTER, then CTRL + X).
      6. Apply the changes by typing: sudo netplan apply

      Things to Keep in Mind

      Make sure the static IP you pick isn’t already in use by another device on your network to avoid conflicts. Also, keep a backup of any config files you edit just in case things don’t go as planned!

      Hopefully, this helps you get your USB RNDIS Ethernet device set up with a static IP. Don’t hesitate to reach out if you hit any snags!




    2. Setting a Static IP for USB RNDIS on Ubuntu

      To set a static IP address for your USB RNDIS Ethernet device on Ubuntu, you can either use the Network Manager GUI or edit configuration files directly. If you prefer the command line, editing the configuration files is a straightforward approach. First, identify your USB device’s name with the command ip a. Look for an interface typically named usb0 or similar. Once identified, you can edit the Netplan configuration file located in the /etc/netplan/ directory. Create or modify a YAML file (e.g., 01-netcfg.yaml) to include your interface with a static IP address. It should look something like this:

      network:
    version: 2
    renderer: networkd
    ethernets:
        usb0:
            dhcp4: no
            addresses:
                - 192.168.1.100/24
            gateway4: 192.168.1.1
            nameservers:
                addresses:
                    - 8.8.8.8
                    - 8.8.4.4

      After editing the file, apply the changes by executing sudo netplan apply. If you prefer using the Network Manager, you can set the static IP via the GUI. Right-click on the network icon in the system tray, select Settings or Network Connections, find your USB device, and then configure IPv4 settings to ‘Manual’, entering your desired static IP, gateway, and DNS servers. Regardless of the method you choose, ensure the static IP is outside the DHCP range of your router to avoid IP conflicts. It’s also a good idea to back up existing configuration files before you make any changes, allowing you to revert if anything goes wrong.
