Good deal, but this adapter gets terrible speeds, even when compared to a standard gigabit ethernet port. Tested same computer, same server, multiple runs on speedtest.net, and i get average 350 mbps on this vs. 500 mpbs on gigabit ethernet port. At other times i've used this adapter, I get only half the speeds. I have a cable matters gigabit adapter that gets much faster speeds than this 2.5 gbps adapter

Is this better than a USB to Ethernet adapter?
Maybe I misunderstand the question... but that is what this is. Instead of being capped at gig speeds, though, it can handle up to 2.5. Good for folks with multi-gig networks (2.5 gig switches, etc.) and don't have the ability to put a 2.5 gig NIC (network interface card) in their machine.

My apologies, I meant USB A to Ethernet. If that was better than this one.

USB-A is a type of port not a speed.
So you could have a "new style" USB-C running at 480Mbs USB 2.0
and a "Old style" USB-A port running at 20Gbps USB 3.2.
You can really tell the USB version and speed from the color of the connector

it matters a lot what kind of port you plug it into.are you using a usb-A to USB-C adapter? even within USB-C there is different speeds.

I love the form factor of USB-C, but unfortunately not all C ports are made equal. USB-A was generally uniform for a very long time, but C is not and like my work laptop the performance on each C port is different. Even though they are right next to each other. One is basically usb 3.1 and the other is thunderbolt but that's for the docking station or the charger to the plug into.

Yea I'm well aware of the varying speeds of usb-c ports out there, and their confusing naming conventions. It was plugged into my MacBook Pro, which has thunderbolt 3 ports (40 gbps) all around. Used cat6 cable plugged directly into 2.5 gig port of my router, which is plugged into the 2.5 gig port of my modem. Also tested it on my office laptop with usbc 3.2 gen 2x1 (10gbps) with similar results. Maybe mine is just a dud

Unfortunately, I didn't end up buying another USB-C to 2.5 Gbps Ethernet adapter after that. Others here seem to have had different experiences, so maybe mine was just a faulty unit.

From my limited research around Prime Day, 5 gbps USB Ethernet adapters in general are in a much worse spot than 2.5 gbps. I believe it's a combination of a few things:
  • 5 gbps is just starting to gain traction. Drivers aren't mature. OS's are less likely to be ready for them. And the most of the hardware itself is early gen stuff that can use revisions.
  • Although listed as 5 gbps, which matches USB 5 gbps speeds, these adapters many not perform well on 5 gbps USB ports. Maybe 10 gbps is what's needed for 5 gbps Ethernet, or maybe newer models will become more stable on a 5 gbps USB port. But for now, I'd recommend only plugging a 5 gbps USB NIC into a 10+ gbps USB port.
  • Copper/RJ45 connections aren't as power efficient as fiber. Newer 5 gbps Ethernet hardware likely isn't built efficiently either. Many people reported better stability when using an adapter with a separate input power, like this [amazon.com]. It is likely that a lot can depend on how much power your USB-C port can supply to the adapter. And if it's not enough, you might be better off with an adapter that can take a separate power supply.
Don't take any of this as fact. Just the ramblings of someone who spent some time researching 5G USB Ethernet adapters out of curiosity over Prime Day. My "information" is based on comments in product reviews, Reddit, and other forums. Not first hand experience. I didn't end up getting a 5G adapter, as my network is mainly 2.5G right now. I'm waiting for 5G Ethernet to mature more before impulse buying adapters.

cool, since others are warning about speeds, did you happen to speedtest?
