anyone find that USB ethernet adaptors are generally rubbish and/or bordering on false advertisement.

i have a "gigabit usb ethernet adaptor" made by Plugable.
however as it only has a USB2 connection (as it states on the adaptor) then it absolute best it could ever achieve is 480Mbps.

when i run a speedtest using the connection it tops out at around 60MB/s which is pretty close to the 480Mbps limit of the USB connection.

how do they get away with this?
Plugable tend to be one of the more "trusted" brands but not with branding it seems!

I ensure the spec says USB 3.0/3.1.

If not I avoid!

It works with a gigabit connection, so... Presumably a USB 3 jobbie is what you need.

what "works with a gigabit connection", the actual apaptor states it is USB2.
it can never be "gigabit" if it's only USB2.

It's like some Powerline adapters and their rated speeds... when they have 100Mbps ethernet ports!

i need to make a correction.
when i was doing the tests i wrote down the results wrong.

the "gigabit" adaptor is, in fact, running at 67Mbps, not 67MB/s.

When and where did you buy it? Presently it's the USB 3.0 adapter on sale.

as said in the original post, it's a marked, but not prominently, as a USB2 0 adaptor.

however, even a USB2 device should achieve better than 60Mbps
