SABRENT USB-C to 2.5Gbps Ethernet Adapter, Aluminum USB-C to RJ45 Network Adapter for MacBook Pro/Air, iPad Pro (2018 & Later), Windows, Linux (NT-25GA)

Everything about this just screams quality. I've never seen a special USB-C connector before, but this definitely has that. It's just barely thicker than others, so it's a tad tight going in, but the connection is very secure as a result. The same is true of the ethernet port.It's plug-and-play on every device I've tested. Anything with a USB-C connection seems to get the full ethernet speeds, and without needing driver installation or anything.It easily reaches advertised speeds, fits securely, and is solid metal construction. I don't know what else you could want.

I needed a USB-C to Ethernet adapter for my 5Gbps network to connect to my iMac. After trying many different brands, the Sabrent adapter stood out as the best, offering the most stable connection with minimal dropouts. It’s incredibly reliable, especially if you need consistent speeds for uploading and downloading large documents and files. Totally worth keeping!

Works as expected out of the box on Windows 11.However, if you're on Linux or BSD you'll need to make sure that you're running a somewhat recent version of the r8152 driver. This device uses an r8157 chipset which is supported properly only in newer versions of the driver. I tried to find release notes for the driver to identify when support was actually added but those don't seem to exist anywhere.Even the upcoming Ubuntu release beta - 25.04 Plucky Puffin - only includes version 1.12.13 of the r8152 kernel module. This is fine for other adapters in the family, including 2.5G adapters, but won't recognize or properly initialize the R8157 chip.If the newer driver versions aren't available, a fallback driver will be used that results in very flaky behavior. Connections are negotiated at 705 mb/s, for instance, and actual throughput is inconsistent, fluctiating dramatically over time.Thankfully this can be fixed by finding an updated package for the r8152 kernel module th at works with your distro and installing it. For ubuntu I used the "awesometic/realtek-r8152-dkms" package on github via the PPM method they recommend in the readme.With the latest driver version installed - 2.19.2 when I'm writing this review - the device set itself up properly, negotiated a 5G-BASE-T conneciton, and worked as expected.

Works as expected, BUT I have a one strange thing, maybe it is my M1 Max Macbook, but it shows 100 megabits uplink in the device settings, but in fact it is 5 gigabit transfer speed)

I was a little concerned if this would maintain the 2.5 speed. Runs at full speed and no issues with the connection dropping.

I have 10G wiring and switches in my house so I bought this to speed up the connections on my laptop. I plug it into the brand new Surface Laptop, I get error messages about not being able to provide enough power to this device. I would think that is probably not the fault of the adapter but, when I plug it into another laptop I get errors that the USB device is not recognized. Unplugging and plugging it back in 4 or 5 times will eventually work, but when I shut down and then open the lid the next day I need to repeat that routine all over again. When it does work I get constant disconnections causing streaming video to stop and I need to manually restart. I went back to my old 2.5G adapter from another company and have none of these problems.

I have given this Sargent 5G Ethernet adapter every chance to work using the USB C 3.2 port on my Lenovo P16 Gen2 laptop but it just isn’t happening. It’s pretty rock solid I’m one of my Thunderbolt 4 ports but I need both Thunderbolt ports for monitors. I contacted Sabrent tech support (a short hold time for live support I was pretty impressed), however the tech was just a screen reader, didn’t help much at all, but was polite. He did inform me that there is no firmware update needed or available. The adapter is solidly built, short cable seemed very well put together. But I’ll be sending it back. I’ll go ahead and get the Lenovo 2.5G adapter vs getting a 2.5G Sabrent. I was able to verify compatibility on the Lenovo site. 2.5G will be sufficient for my needs. I always try to get my network stuff with a little headroom vs maxxed out. Maybe Sabrent will weigh in with some words of wisdom. I did give it 3 stars even though I’m returning it. USB C 3.2 should power this little adapter with ease.

fantastic product. saved me from upgrading motherboard on PC. make sure you download the appropriate realtek drivers if needed. It is not a plug in and go type of equipment most likely. 10/10
