Plugable 2.5G USB-C and USB to Ethernet Adapter – Dual-Connector 2-in-1 USB-C to RJ45 2.5Gbps LAN, Compatible with Thunderbolt 5 & 4, USB4, USB 3.0, Windows, Mac, ChromeOS, iPhone 15 & 16

I used this on a QNAP TS-453a NAS (plugged in via USB 3.0 port) and it was easily detected! It has a RealTek (RTK8156) chipset. Connectivity was stable at 2.5Gbps (no disconnects!). Build is plastic. It's slightly warm to the touch as expected but not hot. The only thing I disliked about it was the fact that it makes it a little hard to unplug the Ethernet cable (I used 3 different ones). Worth noting - It uses a USB C and a detachable USB A adapter for versatility I gave it 5 stars mainly because I was happy with the functionality and outcome of this mini project.

this device works as advertised! Im using M3 Max MacBook Pro and wasnt getting speeds that I should have been. I contacted support they responded pretty fast. much faster than I thought they would. we tried a few things which didnt work which they quickly sent me a replacement. I contacted apple to see if they had any ideas and we ended up finding out the problem. it had been my NordVPN causing probs. when I disconnected from the VPN my speeds returned. the drop off was HUGE. I have 2Gbps DL - 1Gbps UL google fiber. my speeds would drop to around 700 Mbps. Anyway, they had already sent the replacement and I contacted them and told them we found out the prob and I no longer needed the replacement but they told me to keep it! my speeds were ⬇️ using this adapter. DL: 1950 - UL: 1020 Thats rare for companies to do these days so I said thank you. I highly recommend!

Full disclosure, I used this for a very specific use case. I recently upgraded my entire home network to 2.5 GBe and while all of my computers already had NICs that could handle that, my Synology DS920+ didn't. For the uninitiated, this NAS is actually a great little package that has most of the features of its bigger counterparts, with the exception of native 2.5 GBe support (neither on-device nor through expansion). This adapter was on the community sourced list of 2.5 GBe adapters that would work for the upgrade. I can confirm that it works. It takes a little bit of setup on the device, but once you enable it and install the driver, it works perfectly. I'm actually kinda glad since this probably ends up costing a fraction of what it would be if Synology offered a first party solution. This dongle is small enough to tuck away behind the NAS so that it's completely out of sight and I'm able to saturate it fully with around 200 MB/s transfer speeds, which is definitely an upgrade from the 90 MB/s that I'm used to seeing. I did briefly also test this on my M1 Macbook Pro (since the onboard wifi card is actually kinda terrible) and can confirm that I was able to get full throughput on that device as well.

Bought a few of those over time as I upgraded my ISP connection speed to 2.5Gbps. Very conveniently comes with USB-A/C adapter and had no failures over the couple of years. The network connection is stable and as fast as advertised when measured with iperf3. Good deal for the money as well.

This is a voluntary revised review because it sounded I was maligning the product. In performance tests with iperf3, an average speed of 2.34 Gbits/sec was attained point-to-point between two such devices. Note that you need the right device drivers activated. So the product basically works and gives you the possibility to speed up your network with plug-in adapters. In terms of practical, sustained speed, I get around 125-130 MB/s (about 1 Gbits/sec) for ssh/scp transfers. The real problem is copying large files over NFS-mounted directories. I will get that ~130 MB/s for 10-15 seconds, but then the rate drops drastically to < 1 MB/s. It could well be a NFS tuning issue. (I have yet to test SMB mounting.) The devices feel only slightly warm so overheating does not seem to be happening. I still stand by my earlier comment that in the future, I would look for true motherboard support and skip the plug-in adapters altogether.

First off, I tested this on OS X Mojave, Catalina, and Big Sur on 3 different machines and the results were the same for all three. You MUST install the latest drivers from the Realtek site to get 2.5Gbe speeds, otherwise it will only work as a normal Gigabit ethernet connection (and a sub-par one at that). I repeat, if you don't install the drivers, the built in OS X drivers work only as a gigabit ethernet plug. You can check if it's installed right by going to the Apple menu, select "About this Mac" and then click the "System report" button. In the window that then opens, on the left side click on "network". You should then see in the top right section "USB 10/100/1G/2.5G". Click on that and in the window below that's filled with lots of tech jargon there is a section called "Ethernet - Media Subtype". That section should say "2500Base-T". If it says 1000Base-T you didn't install the drivers correctly and you aren't getting 2.5Gbe speeds. So I unhooked my built in ethernet and tested only using this USB dongle. The dongle overheats within 15 seconds of transferring data at 2.5gbps speeds, then slows itself down to worse than gigabit speeds. This is using 5 foot Cat 6a cables, which should be far above the spec needed for 2.5gbe. Testing between a PC with a dedicated 2.5Gbe PCIe card, a single 62GB file took 10 minutes over the built in the built in gigabit connection of my MacPro, but took almost 20 minutes using the 2.5Gbe connection. (Both machines were using SSD's also) Looking at the traffic on my 2.5Gbe Qnap switch, I could see the transfer spike at the start up close to proper 2.5Gbe speeds, but then rapidly fall below normal gigabit as the adaptor overheated. This happened on another 2.5Gbe USB dongle (Also Realtek based) I purchased at the same time. Based on the reviews I knew overheating would be a problem, but I didn't think it would be this bad. The CableCreations plug is larger then the other one I bought so I hoped it would have better cooling, sadly it does not. I bought some small heatsinks off Amazon also. I'm going to tear the dongle down and see if applying a proper heatsink will help with transfer speeds. The moral of the story is while these do "work" they are just not that good. They are OK for quick bursts of data, but if you need 2.5Gbe, you probably are gigs and gigs around, and they are BAD at that because of the overheating. I'm going to break down and just buy a Thunderbolt 10Gbe adaptor I guess.

Truly Plug-N-Play, but you have to remember NOT to connect the device to your USB-C ThunderBolt until after you have installed the device driver package from the URL in the instructions AND have rebooted your PC. If you do NOT follow these steps exactly, the 2.5Gb modem will NOT respond.

UPDATE: before packing this up and returning it, it occurred to me that my Xfinity gateway might be the bottleneck. I Googled it and sure enough, there’s only one port on it that supports faster than 1 Gbps speeds and I wasn’t plugged into it. I swapped ports on the gateway and boom. I got the full speed of my Gigabit plus package and a smidge more. If you’re testing it based on speed from your modem/router, consult the docs to see which of any ports go fastest than 1 gig, then make sure to plug it into the correct port. ——- In the product description, end of the third bullet point, it says "some core features require driver install on macOS." Okay, not a problem. Bought it. Then, when I went and tried to get the driver from their site, they had a message that there are no drivers for macOS 11 and above for this Realtek chipset (see attached image). macOS 11 basically released with the M1 Silicon in 2020, meaning this has no support for full-speed on any newer macs. DOES IT WORK: Yes. It works as a 1 Gbps network interface on my MacBook Pro M3. DOES IT WORK AS ADVERTISED: No. To unlock 2.5 Gbps speeds it needs bespoke drivers and they're not available for Apple Silicon macs (M1, M2, M3).

購入後、まず購入したばかりの、DELL inspiron 14 2-in-1 7420(Win11 Pro)で使用。 (この機種には、有線LANポートがありません) 回線は、auひかり ホーム5G ブロードバンドスピードテストは、6カ所くらいで行いました。 (テストサイトによってかなりばらつきあり) 時刻:23時頃 ダウンロード:Wi-fi 300mbps→本アダプター 1100mbps アップロード:wi-fi 550mbps→本アダプター 2300mbps (いずれも最速値) その後、ALIENWARE17 R5に接続して利用しようとしたところ、 ・製品を認識しない ・接続が一時的に出来るがぶつ切りになる(Windowsのデバイスの着脱音が鳴ることもあり) と、とにかく不安定。 そこで、製品名から検索をして、公式からWin11用ドライバーをインストールしたところ、 全て解決されました。 現在、大きなサイズのファイルをダウンロードするときしか使っていないため、 安定性や長時間の耐久性は評価できないが、 短時間での接続での速度を見る限り、スペック通りの数字が出ており、 価格と合わせて大変気に入りました。 また、USB Type-CとAのアダプタも紛失しないようにゴムでぶら下がっており、 地味に重宝します。 お薦めです。

Das Teil ist sein Geld wert. Durch die Standard 10/100/1000 MBit Karte wurde meine Gigabit 1000er Leitung nur zur Hälfte beim Speed Test mit etwa 500 MBit ausgereizt. Nach dem Anbringen mit einem Cat 8 Kabel und dem 2,5er Adapter an den USB-C Port verdoppelte sich bei mir die Leistung auf fast 1000 MBit im Speed Test. Das hat sich also voll gelohnt für mich. Es ist nochmal merklich schneller geworden.Nur der Treiber war veraltet auf der Hersteller Seite. Es gibt einen Neuen besseren beim Chip Hersteller.....

It's working perfectly fine, I used it with my desktop pc and with tiny pc. I am using it for PFSENSE, Pfsense does detect it on tiny Lenovo pc M93Q, but you have to plug it on yellow usb port, otherwise it won't work, will keep disconnecting. Other option, if you are plugging it to tiny pc, is to install proxmox, this usb adaptor could be put in any USB port, proxmox will detect it and then use it in any VM\CT. Regards, M

This was my 2nd unit and they work great. Tested it with iperf3 and sustained 2.35 Gbps in both directions with a known good 10G nic, for about 30 minutes continuous with no problem, and normal amount of heat felt. Works plug and play on Mac Mini/Studio in M1 and M2. We will buy 6 more of these. My criticism is I wish the C to A adapter was detachable. In many cases users are only using the C end and the A end just dangles there potentially getting damaged. Rather just store it somewhere else. Chipset is Realtek RTL8156. For QNAP, does not work out of the box, there’s a Realtek driver which is community compiled available on GitHub that needs to be installed.

il dispositivo non viene visto dai nap qnap e non è possibile installare dei drive unix con cui farlo rilevare. Testato su un ts251a. E' necessario prendere il prodotto QNAP QNA-UC5G1T che costa 3 volte di più ed ha un chipset differente. Tenete presente che per saturare la banda delle interfacce di serie (gigalan) dovete avere un nas che ha installato almeno due ssd sata in raid 0.
