USB Type-A or Type-C to 5-Gigabit Ethernet Adapter [10/100/1000/2500/5000 Mbps]

It's the same thing as the QNA-UC5G1T from QNAP, but at about half the price (I got the Sabrent one for about $50 when the QNAP one was around $110). For both version you want to use the AQC111U driver from Marvell. Both devices use it, have the same features, and perform the same.I have both, and I personally think the Sabrent one is even better because it does not appear to get as hot as the QNAP one.

I've tried various other 2.5GbE class USB NICs, and this worked out of the box as intended. For those seeking 5GbE speed: do note that you can't quite reach it due to USB protocol overhead.

Box, manual, and device itself all say "5 GbE". When I plug it in, it claims to only be a 2.5Gbit device. And even with a high-quality Cat 6E cable that gets 10 Gbit to my other device's 10 Gbit port, it will only connect at 1 Gbit. I have tried plugging in to two different switches, 2.5 GbE, 5GbE and 10GbE capable ports, with multiple different cables, and 1 GbE is the fastest it connects.If I even got the 2.5GbE it tells the OS it supports, it would be tolerable, but I can't even get that, much less the 5 GbE it says on the outside and on the box it supports.-- Update: Tried it in Windows. In Windows, it claims to be 5GbE, but only connects at 2.5GbE.

Replaced a Killer 2.5GbE adapter that was flakey (which apparently is the norm for them now sadly) and this worked out of the box, no issues, haven’t had to think about it since install. I have it connected to a mini itx board that has USB C but no available internal PCIe slot for a 10GbE adapter. This is the next best thing.

Context: I was a network engineer for years before moving into other areas of technology and moving into management. I am not the stone-cold expert I once was, but my tcpip and networking chops are still first-rate even within technology circles.I've used hundreds of usb network adapters over the last decade. I've hacked firmware and drivers to get them to work in kali and performed pen-testing. I've aggregated them in strange configurations to get better throughput. This is easily one of the worst adapters I've EVER used, for the following reasons:1. This adapter does not perform consistently with a given set of settings. Results are not reproducible. the very first time I plugged this in, I got 2.5g speeds. This was cool, but the adapter would reset whenever there was a sustained. Having flow control on at the switch fixed this for a bit. Then I couldn't even get 1g speeds despite it reading a 2.5 g link. Then I realized this only works on Big Sur if you disable sip -- I did that and installed the driver and have never gotten even 1G speeds again. I spent an entire day testing every combination of settings on both the switch and the adapter. At best I can get 1G speed and usually half that2. The fact the driver requires SIP to be disabled is pretty unacceptable. You have to disable useful security features even to use this on a mac which is irresponsible on behalf of the manufacturer.3. This isn't really a 5g adapter even on paper. It has a 5Gbe controller, but it's limited to ~3 due to the usb interface it uses. It's pretty hard to imagine how that happened except for gross negligence.Honestly, buy ANY other adapter. Or just throw $70 in the garbage and you'll still be ahead the frustration of using this.

Good for DS 918+

und bis zu 340MB/s Übertragungsgeschwindigkeit

Works very well with Linux kernel 5.10 and greater. Windows needs latest drivers from the website (the one stored on the device are outdated).Speed is only limited to 3.5 GBits due to the USB bottleneck. But that's ok.

Good product

Just setup the home 10GbE networking and use this on my laptop that have only USB 3.0 port, I also tried this in the Synology DS1819+ with DSM 6.2 but once update to DSM 7.0, the DS1819+ will not be able to recognize this device.Overall, it is a good device to bump up from 1GbE to 5GbE. If your laptop does not have Thunderbolt 3, you can also connect this device with the Type-C cable that comes together with this device.

For 5gb adapter...its Super fast.. draws a bit of power, runs warm, it's heavy but works well

So we have a USB 3 to 5 Gigabit ethernet that work very good under Windows. It is driven by a Marvell AQC111U (Aquantia). Since it is a USB 3 5Gigabit solution, the Ethernet throughput is capped to a bit over 3 Gigabits. Still faster that Realtek 2.5G Gigabit Ethernet solutions, but not by far.I think the biggest issue is the driver support. For Windows we still have the older Aquantia drivers released in 2019. Windows 11 works. They still work great under Windows but they are not reliable under MacOS 11. Under Linux they work fine, but if Marvell does not keep the driver alive, they might become obsolete quickly.My adapter became the companion of my laptop, since it is plugged to a dedicated USB controller, its performance is very good. Pity that such a great product gets crippled by driver support uncertainty. I think a solution based on Realtek 2.5 USB3 chipset will be a better option in the long term

Works as described! Great product!

One of the few 5 gbps ethernet adapters for both windows and mac (allegedly), this sabrent adapter features a robust aluminum enclosure, and two different USB cables (USB-A, and USB-C). The adapter comes with a mini CD that includes the drivers. Unfortnately I wasn't able to get the adapter to work with my Macbook pro. The adapter would show power was getting to the unit however the drivers never properly registered the device in the system. The adapter does work well under windows, however. Make sure you keep the drivers CD because they're a little difficult to track down from the Sabrent website.

Spoke with Sabrent, nice support. Unfortunately, they could not help much with my particular setup.This 5G adapter only works in 2.5G on macOS Catalina, I will be testing other systems. Sabrent support agrees that it seems that the adapter is being treated as their 2.5G adapter, even shows up that way in macOS (see pic). It's not an issue with speed, it's that their 5G adapter is showing up as their 2.5G adapter.Without installing drivers, the adapter would connect to a 1G switch at 1G. Cool. But no options were present in the network control panel to change adapter speeds above 1G. When using two NT-SS5G adapters (one on each 2016 MacBook Pro with a 12 foot cat 6 cable in between) auto crossover would only connect at 100 Mb/s. The drives in the MacBook Pros are currently doing 1,600 MB/s.I had to install the macOS driver to get the NIC speed options in the Network preference pane. Then I could set the adapter to 5G using auto crossover. Once both were set I ran multiple speed tests, all hard lined at 2.5G.Seems like a good adapter but you might as well get the 2.5G version if using current operating systems. Seems like all these little N-Base adapters are fine up to 2.5G and then fall flat. You need to get a proper 10G adapter (N-Base or dedicated) to get better than 2.5G. Then you get AVB support too!Makes for a nice hand warmer. 😊

I used this with the other end plugged into this SFP+ connector from https://www.amazon.sg/gp/product/B089D1ZYCJ to MikroTik CRS305-1G-4S+IN, and tried to transfer data with another 10GbE device. The SFP+ connected to this adapter strangely reports having 10GbE connection. This however screwed the download transfer from the 10GbE device, which the bandwidth was brought down to even less than 200mbps, possibly by bugging out the flow control as the 10GbE device and switch still thinks they are talking to another 10GbE device. Enabling/disabling flow controls on all the devices including the switch do not solve the problem.To workaround this I have to reduce speed of the 10GbE device to 5GbE for now and they gets around 3.8 Gbps bandwidth.

I got this to dock my laptop, which came with only a gigabit Ethernet and wireless N. I use it pretty much to transfer larger files and it serves its purpose perfectly. I would definitely recommend this product.

I want to share only positive thoughts regarding this product, but I was surprised by its weight.It looks like a hummer (car) it works like it, so the weight is a part of it.It helps me day by day to solve network issues.

I saw this product as part of a review in one of the "ServeTheHome" videos on YouTube. I bought it to go with my aged laptop, as the built-in LAN port has bent pins and works only part of the time. The Sabrent USB LAN adapter is vary solid and sturdy. I have only run the unit at 1 Gbps, but I have seen transfers as high as 90MB/s.

This product is great. I purchased a QNAP NAS that supports 10Gb Ethernet, and a switch that does the same. I wanted the fastest network device that I could purchase for my computer. I purchased an internal card with my new computer but was saddened to discover that it only supported a PCIe x1 card, when the card I purchased was PCIe x8. Looking around I could not find any PCIe x1 cards that supported any faster speeds than 1Gb ethernet. Boo. I found this card that connects over USB that promises 5Gb connection. So, I purchased.Here are a couple of excellent features about this card:1. It does not require any external power.2. It supports 5Gb ethernet with a CAT 5e cable over short runs (I am using a CAT 6 cable for my install).3. It has the driver ON THE DEVICE--you plug in the device and a virtual CD-ROM drive pops up with the driver attached. Excellent.4. The driver will update over Windows Updates optional updates -- Check for updates, find the optional updates, and find the driver update for the card.5. The device gets warm but dissipates heat well. It does not get hot.6. It is larger and heavier than any other USB network device I have used but it is not obtrusive. Easily portable.7. To connect to the computer, it supports either a USBC port or a USB A standard port. It comes with both cables.8. It connects at full-speed 5Gb.I have tested transferring files to my NAS over 1Gb and 5Gb. My transfer rates are closer to a 2Gb Ethernet adapter, but they are definitely faster than 1Gb. If you are looking for faster transfers there are likely a host of variables that affect this...speed of the remote storage, speed of the switch and networking, speed over the USB port, and speed of the local storage. I have tested on 2 different computers, 2 different NAS devices and get similar results, about 2Gb transfer rates.I actually have no idea what the "Sheerness" rating means. Is it shiny? I guess. But how would that rate the product any better? No clue.Great product. Feel good about this one.

Works great for a USB ethernet adapter. I was running it at 5gbps just fine. Happy customer.

Less expensive than others and works better

Tested on my window 10 and ubuntu, with transfer rate 400mb per sec, type c adaptor, quite nice without too hot.

I have this connected to a Dell 5060 via the USB-C port running CentOS 8 Linux. Upgrade to a 5.x kernel to get the aqc111 driver. Used iperf3 against a QNAP with bonded 10GBps NICs (showing 20Gbps link speed)With MTU 1500 the Sabrent gets ~2.45 MBpsHowever, update to MTU 9000 (which matches the QNAP MTU) and the throughput jumps a full Gbps.Summary:[ ID] Interval Transfer Bitrate Retr[ 5] 0.00-10.00 sec 4.02 GBytes 3.46 Gbits/sec 0 sender[ 5] 0.00-10.01 sec 4.02 GBytes 3.45 Gbits/sec receiver

The most important thing about this adapter is the chipset. It uses the first usb3.0 to 5GbE chip released called the aqc111u. This chip (and thus adapter) has support in the mainline linux kernel (module name: aqc111), as I have verified. It also has a plethora of ethernet/offload features that keep CPU usage/interrupts down:- rx/tx checksumming- scatter-gather- TSO- GSO- GRO- and a few other less important featuresI haven't tested throughput or stability yet, but will be connecting it to another one of the same that's still in the mail with a very short custom cat6 cable. I'll update after testing if I remember to.I've owned Sabrent before and haven't had any issues, I've heard many good things about the chip in this adapter and hope it lives up to my standards (or at least beats out a usb3 host-to-host debug link) If you think about how fast a 5GbE link is, that's a 0.2 NANOseconds between bits...that's very fast.

So, I picked one of these up for the price / performance vs a Thunderbolt Ethernet adapter. 5GE vs 10GE isn't too big of a difference when the costs are compared. Laptop doesn't do TB anyway and the ones that say they do don't really either.Tested this out on both Linux / Windows and it loads everything and comes online w/o any issues.The port on the actual adapter is a Type-C in which you're provided 2 cables as stated on the description. I didn't use either of them as I have some C cables already that are proven good.I was able to sync up at 2.5GE to my AP and the full 5GE to my new 5G4T Qnap card.Throughput 5<>5 on my Raid 10 is 3.5gbps or peak of 400MB/s which is a limitation of the drives being spinners and not SSD's . 5GE is a perfect fit for the speed cap of the drives and compatibility doesn't seem to be an issue running kernel 5.9.x+.
