D-link powerline adapter set — Only used them a short while before upgrading to a mesh wifi, I'm fairly sure they were 300Mbit, but here's a photo of the back https://i.imgur.com/ftoCr0d.jpg . Much easier than trying to type all the details, and you can look it up to double check.
Sorry, no ethernet cables, they've all been gobbled up by various PCs or consoles.
But I hope they can help you with that tricky dead spot of wifi, or where you just don't want 100m of ethernet cable :)
