Plugable 5Gbps USB-C to Ethernet Adapter, Plug-and-Play Realtek RTL8157

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.

It definitely gets your fiber connection to the full 5 gig speeds advertised and it does a great job at connecting to a dock as well

Got it to test my Fiber 5 Gbps speed from my router. Plugged into the routers 5gbps Ethernet port, using a cat6a cable, and plugged this into my iPhone 15 Pro Max. It immediately detected Ethernet and was ready to go. No drivers or anything. Speed test shows just under 5gbps on the download, upload shows much slower but best I’ve been able to see is around 1.5-4 gbps on the upload. It’s possible it’s just an issue with speed tests not spending enough time testing the upload side. It does get warm to the touch however, good if you need a hardwired option for your iphone/ipad, or other USBC device.

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.

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.

Plugable company states this does not work on Android phones, but I had no problems using it to access/install files on several android phones. Very happy with this and other Plugable brand products.

Brand new adapter stopped working a few minutes after plugging in. Edit: Replacement runs very hot. This Pluggable ethernet adapter with Realtek 8157 chip is USB 3, not USB 4, so it will not support full 5 Gigabit speeds. The max link speed it will do is 2.5G. Misleading item description.

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.

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

Another cheap no-name adapter melted under heavy use, this one was flawless and faster!

Neede an ethernet adapter and this seems to work well after 4 months of use. Connects my Apple MAcBook Air directly to the router Seems to get a little warm but not hot! I hope it lasts as the price is not cheapm but less than buying from Apple

Achieves the full speed from my connection. Solid product

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
