Cable Matters USB C to 4-Port Gigabit Ethernet Switch for Network Sharing on The Move, Thunderbolt Ethernet Splitter, USB C Gigabit Switch, Compatible with Thunderbolt 5/4

Just what I needed, multiple ports of a switch on a usb-c Ethernet adapter. I’m bragging about this one to my fellow service technicians. This one item removes an Ethernet adapter, a switch and a power supply from an already overloaded Milwaukee tool back-pack. Less is often more! (Especially when your the one carrying all this stuff around every day)

I do a lot of new cluster implementation, and often require a small switch as networking isn't alway set up when I'm starting my work. This little thing is really useful, and takes up much less space in my traveling office than the old 5-port switch I used to carry. The best aspects of this are that it shows up as an Ethernet NIC on the host system (effectively making it a 5-port switch), and it's BUS-powered. Only thing I dinged it on was the plastic construction brings its sturdiness into question. Will probably be fine since the switch it replaced was also plastic and never failed despite living in a backpack for 3-years.

Basic Ethernet switch USB C so it's convenient to add to notebooks without Ethernet ports.I use to configure ethernets devices in an environment with multiple cables so it's perfect for what I use it for. Unit is still newish so reliability is still a wildcard. Good so far I update if anything should change.**UPDATE: GOOD NEWS. Using in a mission critical capacity 24/7. Unit holding up. Bought another to travel with.

Tested with Arch Linux on x86_64, 6.0.y through 6.5.y kernels and Linux-Firmware 20220913 to 20230908. Kernel modules are auto loaded on reboot, interface just works under networkmanager or systemd-networkd control.Iperf3 testing shows 920+/- 30 Mbps using bbr congestion protocol on both ends, which is as good as you can expect from a properly working gigabit connection + usb3.Contrary to reports I have seen elsewhere for this device, it does NOT stall / crash your whole LAN when the USB host device reboots or powers off. However, it is very helpful to the stability of this device to turn off certain features using ethtool:ethtool -K <interface name> tx off rx off scatter-gather off

This switch has solved so many problems that I have had to tap into an ethernet network.I am a Controls Engineer and I program factory machines. Often I need to connect to the network on remote i/p devices when the main switch is in the main cabinet and too far to connect. I use this switch on my PC, then I use 2 ethernet cables and one female to female connector end to tap into the network at and device.

Very easy to setup and use. Love the fact that you do not need to also carry a power supply.

As it is 2nd repurchase , the product is what I know and extremely good. However, the shipment was not easily completed as it has incomplete address label. Better to review it how it was changed from what I typed in Amazon and how it printed on it.

Very happy with this network switch. It makes computer network troubleshooting much easier. I also use it when commissioning and troubleshooting solar inverters. Often times we run a single network cable to commercial systems, and being able to jump into the network at any device is very helpful.I do wish it had a couple standard USB ports, so I wouldn’t have to lug around an adapter, if and when I need one. It’ll be a long time until I don’t need that.I use it with my Dell XPS 13” laptop and it has 4 usb c /thunderbolt ports. I’ve also tested it with a 15” Mac book pro. Both work well.
