Yellow Flashing Light Ethernet Port

but it is unsettling to have the upstream light flashing

I'm using this with my Macbook Air that only has USB-C ports and no ethernet port. This adapter worked right out of the box to give me an ethernet connection. Just plugged the ethernet cable in to the adapter, connected the adapter to the CPU's USB-C port, and my computer connected to my work network flawlessly. The wifi at my work is not great, so this adapter is giving me a fast network connection now through ethernet. I did a speed test and I'm getting approximately 500mbps upload/download speeds with this adapter, which is fantastic. I also appreciate that the adapter has LED indicators. One light shows there is a connection (green). The middle light shows there is power (White/blue). And the 3rd light blinks orange to show there is activity. Having these lights could come in handy if I need to trouble shoot, which is very helpful. The build quality is also really good. This feels like it will last a long time. The cable seems sturdy and the ethernet cable plugs in securely into the adapter's port. Overall, I'm happy with this adapter and it is working very well.

A reliable solution for users of laptops without an Ethernet port.

Great Canon Battery Grip this time with Ethernet port.

I always take my multiport adapter with me whenever I'm traveling. Super handy especially the ethernet port.

Cox just upped my speed ... needed an approved modem with a gigabit ethernet port, more channels and RAM. Works great with my Netgear WNDR3700 router. Expect it to go a few years!

It works well, arrived quickly! I have used the ethernet port and the US-B. I am happy to have it, knowing that I can connect to anything to might need.

My laptop doesn't have an ethernet port. This USB adapter is a great solution.

Works great for ethernet, a USB-C lapel mic, and a webcam. I wish it had an audio port for headphones, but I guess it doesn't need to have everything for it's price. The build quality is a lot higher than I expected, very sturdy. The USB-C male cable (to connect to computer) is a bit short, but that likely improve durability.

My office only had one Ethernet port and this bugger gave me 2 ports and made my WiFi signal stronger. My room had decent WiFi coverage but nothing to write home about. My only complaint is that it wasn’t fast out of the box and I had to make some tweaks to get it working nicely with my other ap. It’s no where near as fast as it could be over wifi but the wired speed is perfect which is where it really counts for me. Using iperf3 between router and my computer I plugged into Ethernet I got the same speeds with and without this device in the chain. Over WiFi though itis about a third of the speed after tweaking it. Still working out the bugs but I’m confident it’s a setup error because it kept getting faster as I make little tweaks because when I started it was under 100mbps over iperf3
