Customer Feedback

1>In case you are wondering if this particular gigabit ethernet will work with the Nintendo Switch, it does indeed work 100%. Works at 1Gb speeds right out the box. Best part is you can see from the pics I attached (2 images) it will fit without any issue from the back of the Switch’s dock. Once you plug this in, the wired icon shows up in the switch’s OS menu and your connection will work natively without any issues.

2> I was having a weird issue on my home network where my router (Thanks AT&T) was acting completely bonkers. I was having issues with ARP/IP addresses. I spent hours trying to diagnose this issue and I came to the conclusion that my NIC or the router was the issue. I decided that buying this lil guy would be useful for future network troubleshooting and I couldn't really reset my router. I plugged it in and my router was yet again answering my computer again. I got the ok to blow away the router and start over. Now this nic sits in my tech bag to help troubleshoot future issues.

- Price - The price on this makes it something that should be in every troubleshooting kit
- Drivers - Windows 7 Ult seemed to have built in compatible drivers. I imagine windows 10 does as well.
- USB 3 - with USB 2.0, you would be restricted to 480mbps at best
- I am not sure I can really answer this as I didn't use it for an extended period of time.

All in all, if you work in the IT field, this is a product you should own. You often times run into areas where an extra NIC can be useful. Since this can be used in laptops or desktops, is really cheap, and is very compact, I would highly recommend this. Now days, companies are releasing laptops that only include WIFI so this gives you a way to connect over a hard line. Also this works with Windows tablets. I should try it with android and see how it works.

3>This adapter does exactly what it claims! I have a relatively new laptop with a built-in 100 MB network card, but internet speed well above that. The laptop also has a USB 3.0 port and I'm now using that with this adapter successfully. It was very much plug 'n play; I didn't even notice any drivers loading the first time I plugged it in (using Windows 10). The adapter does seem to run a little warm but it is has been used almost every day for several weeks now and has worked absolutely perfectly. I definitely recommend this adapter to anyone with the need to create an ethernet port using a USB port (particularly creating a Gigabit ethernet port using a USB 3.0 port!).

4>Great product! So convenient and handy to have. When using it as a wired connection, speeds have not take a hit, works just as well connected to my laptop as the port on my desktop does. My desktop is in a different room than my modem/router so I use my laptop to make any changes or to hook up using ethernet. My laptop didn't come with a port for Ethernet and I almost didn't buy it because of that but then I discovered these great adapters! It has worked flawlessly so far, I have had no problems whatsoever. It seems sturdy and not easily broken. I purchased this one over others based on the reviews and I am happy I can contribute to the positive reviews!

5>I'm so glad I bought this. It saved me! The wireless connection at my house isn't that strong. One time I was taking an online exam and my answers weren't saving. I began worrying and panicking. Luckily my professor was understanding about it. But the next day I bought this adapter so that I can hook my laptop up to the router directly. I had to download a driver, The downloading the driver part was super confusing because i'm not tech savy and there were absolutely NO directions on their website about how to extract the file after downloading it. I had to google around and then eventually figured out that after downloading the file, you were supposed to save it to your desktop to extract it. I couldn't use the CD that comes with it because my laptop doesn't have a CD-ROM which is why I had to download the driver online. But once you have downloaded the driver, you just plug the usb part into your laptop and the ethernet cable into the modem. And it instantly starts working! I didn't even have to mess around with the settings in the computer. Great product!
