A cable that directly connects a USB Type-C port to a wired LAN port has been released, allowing you to achieve a high-speed, stable internet environment for your Nintendo Switch or smartphone with just one cable
By connecting a conversion adapter to the USB port of the Nintendo Switch (first generation), smartphones, and tablets, high-speed Internet connection via wired LAN is possible. However, it is a hassle to prepare a wired LAN cable and a conversion adapter every time. Sanwa Supply released the 'USB Type-C LAN conversion cable' on Monday, June 30, 2025, which solves this problem and enables wired LAN connection from a USB port with a single cable. Some models of notebook PCs in recent years do not have a wired LAN port, so it seems convenient for business use.

The 'USB Type-C LAN conversion cable' is a cable with USB Type-C on one side and wired LAN (RJ-45) on the other. It comes in four lengths: 1m, 2m, 3m, and 5m, and the cable is 4.2mm.
By connecting to the USB Type-C port of a laptop, smartphone, tablet, or game console, you can connect to a wired LAN. This provides a more stable and faster Internet environment than a wireless LAN connection.
No special driver is required when using it with a laptop; simply connect it to a USB Type-C port and you're ready to go.
When using a conversion adapter between a USB port and a wired LAN port, problems may occur such as 'the MAC address of the PC and the MAC address of the conversion adapter are different, and security settings may affect the ability to connect to the Internet.' The 'USB Type-C LAN conversion cable' supports MAC address pass-through, which can avoid connection problems.
The USB Type-C connector is said to be designed with safety in mind.
In addition, the wired LAN connector is equipped with a cover to prevent its tabs from breaking, allowing it to be repeatedly connected and disconnected.
The standard prices for the 'USB Type-C LAN conversion cable' are as follows.
