MSI Modern 14 C12M Ethernet Adapter Missing Windows 11
You connected a USB-C or USB-A Ethernet adapter to your MSI Modern 14 C12M but it does not appear in Network settings or Device Manager. Or you expected a built-in Ethernet port and found none. The MSI Modern 14 C12M has no RJ45 port – Ethernet requires an external adapter with the correct driver.
This guide covers the correct USB Ethernet adapter types, driver installation, and connection troubleshooting to get Ethernet working on the MSI Modern 14 C12M in Windows 11.
“Brought my MSI Modern 14 to the office expecting to plug into the network switch but there is no Ethernet port. Got a USB-C to Gigabit adapter and it worked after installing the Realtek driver.” – Raziff, IT executive from Kuala Lumpur

Why Ethernet Is Missing on MSI Modern 14 C12M
The MSI Modern 14 C12M is a thin and light laptop designed without a built-in RJ45 Ethernet port to reduce chassis thickness. All wired network connectivity requires an external USB-C or USB-A Ethernet adapter. When an adapter is connected, Windows 11 attempts automatic driver installation. If the adapter uses a chipset without an inbox Windows 11 driver, manual driver installation is needed.
- MSI Modern 14 C12M has no built-in Ethernet port – by design
- USB-C Ethernet adapter using chipset not in Windows 11 inbox driver package
- USB driver for Realtek or ASIX Ethernet controller not installed
- USB-C hub used for Ethernet not compatible with USB-C port on Modern 14

Fix 1 – Install Realtek USB Ethernet Driver
If your USB Ethernet adapter uses a Realtek RTL8153 or RTL8156 chipset (common on USB-C adapters), go to realtek.com/en/downloads or msi.com/support and download the Realtek USB FE or GBE Family Controller Software. Install and restart. The adapter should appear as an Ethernet controller in Device Manager and in Network settings after installation.
Fix 2 – Use ASIX AX88179 Based Adapter
ASIX AX88179 chipset USB 3.0 to Gigabit Ethernet adapters have full inbox support in Windows 11 – no driver download needed. Plug in and Windows installs the driver automatically. These adapters are widely available from TP-Link, Ugreen, and Anker at low cost and reliably work with slim laptops like the MSI Modern 14 C12M via USB-A port.
USB-C Hub with Ethernet
If using a USB-C hub with Ethernet port, ensure the hub itself is powered or the Ethernet port is from a separate Realtek or ASIX controller that Windows can detect. Some budget USB-C hubs route Ethernet through USB 2.0 internally, limiting connection to 100Mbps despite advertising Gigabit. For full Gigabit speeds, use a USB-C hub specifically listing Gigabit Ethernet via USB 3.0.

Fix 3 – Check Device Manager for Unknown Device
With the adapter plugged in, open Device Manager and look under Network Adapters for the Ethernet adapter, or under Other Devices for an unknown USB device. Right-click the unknown device, select Update driver – Search automatically. If Windows cannot find a driver, note the hardware ID (Properties – Details – Hardware Ids) and search for the vendor and chipset to download the correct driver.
Fix 4 – MSI Support Driver Page
MSI provides a USB Ethernet driver package for Modern 14 C12M on their support page. Go to msi.com/support, select Modern 14 C12M, and under Network download any available USB LAN or Ethernet driver. This covers MSI-bundled USB-C adapters that may have shipped with some Modern 14 C12M configurations.
