It's time to move those bits at 2,500 Mb/s

 No idea why people like quoting figures like 2,500 mA (2.5A) for chargers and other devices, well thankfully D-Link have announced the DUB-E250 a USB-C to 2.5G Ethernet adapter.

Opening the box reveals a large plastic holder into which the adapter is firmly held in place (though a complete was of plastic packing) and a paper limited warranty in many languages (that no-one is likely to read).


The adapter has a plastic rectangle with Ethernet socket at the end and a standard USB-C connector at the other.

It just works, plug it in to the USB C ports of a PC, Mac or Linux box and a Ethernet device appears supporting up to 2.5Gb/s networking. No drivers, no installs.

Unfortunately there was no 2.5G infrastructure to plug it into at the time, but it also works perfectly happily with 1G network switches just operating at 1Gb/s speeds. Will probably try in on a iPadPro with USB-C port to see if anything is detected and upgrade the blog if it does.

It costs around £30 on-line and if you have a lot of data to get on or off a PC device and a network to support it, then it's a good option, though most consumer hardware is still only 1Gb/s and there won't be any gain to upgrading.

In future as consumer does move to 2.5G or even 10G then this could be for you (probably more realistically a good device for 'techies' who need to plug into Dada Centre networks and monitor and access services or as companies go back to work and update their networks.
