Plugable 5Gbps USB-C to Ethernet Adapter, Upgrade USB-C Devices Without Ethernet to Ultra-Fast Stable Wired Networking (5X Faster Than Gigabit), Plug-and-Play Realtek RTL8157, Windows/macOS/ChromeOS

Purchased this ethernet adapter when it first came out and it didn't go anywhere near 5Gbs So I returned it. A year later I tried it again and now it works great. Maybe the drivers are better. Now I get very close to 5Gbs reliably and although the device gets very warm, it's not hot which is another plus. I am very satisified now.

Works on Apple Silicon with MacOS26 (miracle, with Apple's mediocre network stack and bug filled OS). HOWEVER: Does not work with Verizon's CE1000A extender, which has a 2500BASE-T upstream-direction PHY/MAC bug. Throttles to 500Mbps. Only option for 1Gbps is to use the 1gbps port only, sacrificing 2.5gbps LAN, or use an unmanaged switched in between Verizon's junk and the RTL8157 chipset.

Gotta say, it looks like Plugable has done it again. Using it for a day so I can't speak to longevity, but the 2.5gbit version has been working great for years - we have several. This 5gbit adapter just plain works on our macs and QNAP multiple speed switch. Maybe 75 feet of old CAT-5 (NOT 5e) with a RJ-45 wall box in the path too. Our legacy 10gbit Thunderbolt adapters require separate power supplies, are large, heavy, not really portable, expensive, get hot, and are slow to negotiate. But, they give us 10gbits which is really nice to have. We have tried most other adapters to get us a more compact and compatible USB 5gbit speed and none have worked consistently - got too hot, etc. The Plugable 5gbit adapter has not become too warm in our use so far, and like I said, connects over normal legacy cables. It seems like a fine evolution to a faster speed and is the next best thing to 10gbits.

It's better than 2.5 gigabit ethernet adapter, but it's not a full 5 gigabit ethernet adapter. My UGreen 2.5 G ethernet can get 2.3 gigabit downstream, and 2.2 gigabit upstream, which is reasonable given the typical network overhead. This Plugable 5 gigabit ethernet adapter got around 4.3 gigabit downstream and 3.2 gigabit upstream. So it wasn't a doubling of speed when switching to this faster adapter. A different desktop computer with an integrated 10 gigabit adapter on the same switch could get 9.2 gigabit downstream, and 6 gigabit upstream, which means that the speed difference is likely due to this adapter and not my network connection. For optimal results, plug it into your laptop directly instead of to your external display. The USB wire may be a little sensitive to bending, and it would probably be better if it were a little stiffer to avoid it bending too much. You get a little more performance by not bending it too much. While my network connection is solid, with this adapter, there was definitely some ramp up time when testing the speed. Sometimes it would be slow, and then the connection speed would get faster. In one test, this adapter dipped down to 340 Mbps when uploading for a while. I didn't notice this behavior as much with my UGreen adapter. It's also worth noting that my Plugable adapter was likely a return. The packaging was previously opened when it arrived. Unfortunately, I don't feel like I got a "new" product. It does feel hot to the touch when connected for a while. It is convenient and portable. You just have to plug it in, and it works. While I do recommend it, there are definitely some areas where it can be improved.

Good adapter: worked without issues in Windows 11 at full 5 Gbps speed without installing extra drivers. Works on Samsung Galaxy Tab S10 tablet as well.

Not a very efficient NIC, but okay for the price. Does not reach anywhere near its full negotiated wire speed. I tested bandwidth performance of this NIC adapter for quite some time with a very capable switch and transceiver modules. It's nowhere near it's 5gb/s mark at the negotiated speed, but it will be better than 2.5gb/s, just don't expect it to perform as advertised on the negotiated speeds above 1gb/s.

It works at the advertised speed. It does get pretty hot when in use

Runs at a perfect 5gbps on macOS. No drivers and it’s easy to setup. There isn’t a better deal in my opinion so I consider this the best value for the money. Compatible on macOS, Linux, and windows 11 from my tests with no drivers. Does get a little warm to the touch but nothing more.

Achieves the full speed from my connection. Solid product

Jala muy bien el chip es Realtek. 2.5 Gb pero alcanza 5 Gb. En cuanto tenga puertos 10Gb probare el máximo.

Works Well, getting just over 400mb/sec on a QNAP Switch. Overall good product. I found that when testing different 10Gbe switches it can be the switch more then this product the issue with getting good speeds above 2.5Gbe

Good

The 5Gbps USB-C Ethernet Adapter (ASIN B0DTBLB6WY) from Plugable came complete with instruction manual. Build quality seems decent, sporting aluminum housing and strain relief. Oddly enough the cable itself is sheathed in rubber. Given the adaptor will likely end up hanging off the side of a desk (due to ethernet cable weight/pulling), I'm surprised it doesn't employ braided cable. In the interest of full disclosure, I picked this up to avoid having to use WIFI in certain environments, and I have not used it above 1 Gbps speeds. That said, even at 1 Gbps it runs hot, but operates as claimed. If you wish to utilize the device to its full potential using Windows 11, you'll need to use Windows Update to pull in the latest drivers.
