As a cautionary tale about the importance of paying attention during online shopping, I ended up buying this device under the mistaken impression that it provided USB 3.0 and Gigabit Ethernet via Thunderbolt but instead it does via USB 3.0 on the host machine. It didn't help that the description on Amazon mentioned Thunderbolt as an interface: perhaps I should complain to Amazon about being misled...

Originally my plan was to use it as a Gigabit Ethernet and USB 3.0 solution on my Thunderbolt equipped 2011 MBA and/or my 2011 13" MBP for the USB 3.0 functionality but no matter, something that will actually fit that requirement is on its way to me and this is still useful for my 2010 C2D MBA as a cost effective all-in-one dongle that offers DP, HDMI 2x USB (reduced to 2.0) and a LAN port.

As a comparison, just buying Apple's Ethernet adapter for the C2D MBA alone cost $29 USD and is only 10/100!

The drivers from Gofanco's website worked with Catalina and Mojave (they've also provided Big Sur compatibility too) and despite being listed as compatible with Snow Leopard - the drivers start from Mavericks. An email to their tech support dept resulted in a URL to drivers for the wrong product which uses a completely different chipset from my device, despite me explicitly specifying which product I was using.

With a bit of detective work I managed to track down the correct Snow Leopard driver elsewhere on the Internet and notified Gofanco so that at least they're aware of what they need to do in order to prevent future occurrences of this situation. These so-called tech support personnel never fail to astound me with their incompetence.

Anyhow, here it is detected in Catalina and happily enabling me to access the Internet via Ethernet. :)

Question time: am I correct in assuming that even though the hub is operating in a reduced capacity at USB 2.0 that this bandwidth is still sufficient for the LAN interface to provide the MBA with true Gigabit Ethernet functionality?

As always, I appreciate any clarifications or confirmations that can be shared. :)

USB 2.0 tops out at 480 Mbps, and that’s without any overhead taken into account. So, no way to get full Gigabit Ethernet speed this way but it should still be quite a bit faster than 100 Mbps Ethernet.

Perhaps they did that to avoid confusing less knowledgeable owners of TB1/2 Macs who wouldn’t know that mDP and TB use the same connector and you can just plug in a mDP device. That’s a very weak excuse though.

A few months ago @Amethyst1 was helping me to get my two Cinema Displays to work with my work MBP. Both of the adapters I use require two of the three USB ports AND BOTH of the MiniDisplay/Thunderbolt ports. That left only a single USB port, which I need for my keyboard and no TB ports for my TB/Ethernet adapter.

So, I got a Moshi…

moshi-usb-to-ethernet-adapter-for-macbook-air-109141-2.jpg

It uses the last USB port to connect to ethernet. But it also has a spare USB pass through port so I can attach my keyboard. Not sure how fast it is, but it does work. Nothing to install, the MBP sees it natively.

Moshi also has a USB-C to Ethernet adapter as well.

Correction - I have TWO USB ports. So, the Moshi has one and the keyboard had the other. But because both TB ports are being used I can't use a TB/Ethernet adapter.

Yeah, it seems to be the best outcome given the technical constraints. At least I now have the option of an Ethernet port available on the MBA and with a reasonable speed. For a bit of fun, I could even connect it to my Cisco router and do some CCNA practice. :D

Perhaps they did that to avoid confusing less knowledgeable owners of Thunderbolt 1/2 Macs who wouldn’t know that MiniDisplayPort (which this thing uses for video input) and Thunderbolt use the same connector and you can just plug in a mDP device. That’s a very weak excuse though.

From this brief experience Gofanco do not present themselves as a competent organisation and I'll look elsewhere in future when I need hardware. Thanks @eyoungren for the Moshi mention. :)

No problem. I think I paid like $20-30 or something small like that. It shows as a USB 10/100/1000 connection and I've hit speeds of about 500mbps down so it's definitely faster than 100.
