Lenovo 4X90F84315 - networking cards (Notebook, Wired, USB, Ethernet, ThinkPad X1 Carbon), Black

Works well, allows wake-on-lan, and saves a USB port. Much better than using a USB network adapter.

Hooked up to my ThinkPad X380 Yoga and had a solid internet connection since. Delivered quickly, packaged well and it works for me, so I am happy!

Ideal for when WiFi signal is poor and a wired network is available

Ordered Thursday night; arrived Monday midday by post. Genuine Lenovo part (Intel chipset). Used with Thinkpad X380 Yoga.

Chris loves it - I bought him the wrong one at first. He didn't love that, oh no. 'Where do i plug it in? It doesn't fit' he said. When he got this one:.. ...'Alll working, thanks Bob!'

Much needed adapter to connect Ethernet to Lenovo ultrabook. Worked perfectly, as new but cost much less than new.

Works very well on new Thinkpad.

Exactly what I needed, works perfectly.

Parfait pour Thinkpad L390 et L380, permet de se connecter avec un câble RJ45, sur le port spécifique de ces machines.

Funziona bene.

Muy conforme con el producto

Works like it's supposed to. I like the light indicators and how flexible and sturdy the cable is.

This adapter works great with the Lenovo X380 Yoga. It connects at 1 Gbps without issue. It was ready to go out of the box, with Windows 10, without any extra drivers. There seems to be a lot of confusion about the type of port that is needed for this dongle. I don't know if it's proprietary to Lenovo, but I've never seen this type of connector before. The owners manual calls this "Mini Ethernet connector" Note: This will not fit any USB port (including USB-C, there's a different adapter for that). This will not fit a mini-display port, nor will it fit a micro HDMI port (even though they are about the same size). The port this will fit has the same logo you see in the picture, which is actually the IT symbol for LAN (three squares connected to a horizontal line)
