Excellent adapter!
I was looking to purchase a USB>Ethernet adapter for my Series2 Tivo. Since the Tivos are known to be a little picky about the adapter used, I did a lot of research to find out what was out there. This adapter kept popping up, so even though it's not listed on Tivo's website ([...] I decided it was worth a shot. It had gotten great reviews pretty much everywhere. The adapter (TU2-ET100) arrived yesterday. The USPS shipping was a bit slow, having actually PASSED my house in route to another hub before coming to me. But the packing was good, and it was in a nice box with a CD and fairly basic instruction book. I did not need either. The adapter itself is pretty light weight, but not fragile. It's a little boxy, but that actually is a good thing as I want it to sit flat. Within a second of plugging this in to my Tivo, it had obtained an IP address from my router and was churning away with full-duplex speed! The world of networked Tivo has opened lots of cool doors, thanks to this simple little adapter! According to the box, this adapter WILL work with the Nintendo Wii, as well. Note to those looking... BE CAREFUL not to mistake this with the TRENDnet USB to 10/100Mbps Adapter (TU-ET100C) adapter, which sells for a similar price (slightly cheaper) and looks more "modern", but only operates on the USB 1.1 specification. Also note... don't waste your time going to Best Buy. They don't sell these, and the guy who offered to help me find it told me matter-of-factly that "there is no such thing as a USB>Ethernet adapter." Sure thing, buddy.

Ethernet for Roku Streambar
I use this on my Roku Streambar SE so I can plug in wired ethernet. The Roku Streambar recognized it immediately and set up was just as easy as the setup for wired ethernet on a Roku ultra. So if you're looking for an ethernet connection to your Roku or Ion/Roku soundbars, I can attest that these works great.

Worked perfectly for my Roku Smart Soundbar
For some unknown reason, Roku did not include an ethernet port on their Smart Soundbar. I mean, why in the world would you want high-bandwidth, low latency connectivity for a high-definition streaming device, right?!? Sheesh. Anyway, they *do* include a USB-A port, and they do support a limited number of USB ethernet adapters, including this specific one. I plugged it in and it worked immediately! Great throughput, no wireless lag, and no saturation of my wifi network with streaming. Note that the USB-A port is the old, rectangular, only-plugs-in-one-way technology and is also has lower throughput than modern-day USB-C ports, so the throughput on this ethernet adapter is limited to a theoretical maximum of 100 megabits per second (mbps). In reality I get around 70-80 mbps, which is more than enough for very high definition content streaming. Highly recommended.

Works with the Amazon Fire TV Stick (2nd generation)
I bought this to connect my 2nd generation Amazon Fire TV Stick to the Internet via a wired connection. It works great. For this to work, you'll also need a micro USB OTG cable (https://www.amazon.com/gp/product/B00CXAC1ZW). No configuration required. Just power down the stick, connect this adapter using the OTG cable, and power the stick back up. It connects automatically. If there's any complaint, it's that its not faster (such as USB 3.0, gigabit ethernet). However, I have yet to read about any successes with a USB 3.0 ethernet adapter working with the Fire Stick, though that doesn't mean it's not possible. That said, this Trendnet adapter should be fast enough for any streaming you need to do. Note: While I can confirm that this adapter works with the 2nd generation Fire Stick, the MonoPrice version should also work (https://www.amazon.com/dp/B00ACPST4M). Theoretically, any adapter with the Asix AX88772 chipset "should" work. Search for "AX88772" on Amazon to find adapters with this chipset, though obviously I can't confirm that they're all compatible with the Fire Stick.

Perfect Solution for Dead Ethernet Port
About a month ago, lightning struck close enough to my home to scramble some of my electronics (including reseting a battery powered clock), and fried most of my home network equipment. The Ethernet port on my desktop PC's motherboard was fried as well. While looking for a network card to replace it, I stumbled across this product. I was skeptical at first, concerned that a USB device would not be able to keep pace with a "real" network card (PCI-E or integrated), but thought I would give it a try anyway. This product turned out to be the perfect solution. Setup took less than 30 seconds, and tests from various websites verified that my connection was at least as fast as it used to be (21.5M download / 2.1M upload as of today). Since installing the product, it has performed perfectly, without fail, 100% of the time. No fuss, no configuring...it just works. Another advantage this product has over an internal Ethernet card is that it is portable. I have not had the need to use it with another computer yet, but imagine I will appreciate it when the time comes.

Great for HP ProLiant ML350 Gen10 connection time ILO5
This review is for a specific use: Connecting a laptop to a Server's ILO so there's technical jargon that may not mean much if you're just using this to adapter to connect your computer to a network. I use it to plug into the ILO USB jack in the front of HP ProLiant ML350 Gen10 servers. You don't need Gigabit speed for this so 10/100 is fine. You can connect directly to ILO5 interface without having to plug the regular ILO network port (in the back of the server) into the LAN and do any other setup on the server. 1 - Plug the USB end into the ILO USB port in the FRONT of the Server 2 - Plug a network patch cable between this adapter and your laptop's ethernet network port 3 - Set your laptop with a static IP address of 169.254.1.3 / 255.255.255.0 / 169.254.1.1 4 - Open up Chrome and go to 169.254.1.2 and you're immediately connected to the server's ILO5 web interface. Super easy, works well, built solidly (enough for this use) and inexpensive.

Great for a Week... Then Suddenly Ghosted Me Like a Bad Date
This Trendnet USB to Ethernet adapter worked fine for about a week—then decided to start dropping connections like it was auditioning for a disappearing act. One minute I’m surfing smoothly, next minute, poof—internet gone, forcing me to reconnect like I’m in some kind of digital Groundhog Day. Supports Windows and Mac OS, sure—but apparently not “stable connection” OS. If you want a gadget that’s good at keeping you frustrated and offline, this one’s perfect. Would give zero stars if I could, but hey, at least it worked for a week!

Works nicely on OSX leopard, Bootcamp XP, and Win 7
The Ethernet port on an old macbook I had was damaged which wasn't a big deal at the time because I connected via WiFi all the time. Ended up upgrading and storing away the MacBook until I decided to dig it out of storage and turn it into a Minecraft Server. Over WiFi we would experienced a few lag spikes so i ordered this to connect it over Ethernet. The thing works exactly as I expected. Handled the connection of 12 people just fine. The minecraft server itself however running on a Mac left much to be desired, so I loaded up XP on Bootcamp and gave it a go again. Connection is amazing with 15 people connected just as if I was running it through the actual Ethernet port. I also tried it on my Win 7 laptop just for fun. Worked perfectly. I would recommend this to anyone who had a bum Ethernet jack on their computer or laptop, or someone just looking for a USB to Ethernet. Fine product with a fine price.

Works great with Google Chromecast (v2.0) out of the box
I bought this to use with a Google Chromecast (v2.0) and it works perfectly. Combined with a USB OTG Y-cable (so has power and comms) it is plug and play. I took it with me recently to a trip to the States and used it with a TPLink WR702N travel router. It meant I could stream for my G4 to the chromecast using LocalCast and YouTube. Never had any stuttering or dropped performance I use it at home with Emby Media Server to cast to a 24" HDMI monitor. It quite happily casts 1080p MKVs from my Blu-Ray rips. Very pleased!

Für den Preis einwandfrei
Habe diesen Adapter gekauft, da das WLAN im Büro nicht sehr gut funktioniert. Das Teil kam, ich hab's an das MacBook angeschlossen und es arbeitet seit der ersten Minute einwandfrei. Auch die Qualität ist klasse - bislang keine Beschädigungen zu erkennen, obwohl es immer hin und her gebogen wird. Top!

Funciona en Windows y Linux
Por buen precio pille esta tarjeta de red usb y me va de lujo para añadir interface fijo a mi portatil. Lo mejor para mi es que tambien funciona con ubuntu 14.04 y lo reconoce a la primera. Probado tambien con raspberry pi 2 y sin problemas, funciona perfecto.

THIS IS A SCAM.
They state it is AX88772A and compatible with Wii, however when I tried it, It did NOT WORK! And its NOT EVEN AX88772A, It's AX88772C Which the Wii doesn't support.
