D-Link USB 3.0 to Gigabit Ethernet Adapter - USB to RJ45 for 10/100/1000 Network - Windows and Mac OS (DUB-1312)

I decided to turn an old laptop into a router using pfSense since I needed IPSec VPN capabilities for work and I didn't want to spend a lot of money on a new router with this capability. Like most laptops, it only has one Ethernet port, so I decided to buy an adapter to add another port. After plugging in the adapter and installing pfSense 1.2.3, for some reason I could only get 50mbps down even though I could get 100 up. I upgraded to pfSense version 2-RC3 and it seemed to use a new driver for the adapter and now I can get the full 100 up and down. So overall I'm very pleased that it worked for what I wanted, and I'm glad the latest pfSense had a good driver for the adapter that allows me to use it at full speed.

You read reviews and they are always mixed. I was attempting to run a customer service program on my laptop for a work from home company. My laptop is a little over one year. However, the program would not run. It gave me a network card error. My ethernet cable was plugged in and my LAN and wireless devices indicated all systems go. The company told me to try using USB ethernet adapter and specifically recommended D-Link. I went to the Microsoft Windows Vista website first to check compatability. Amazon shipped my item today. All I did was insert the USB cable in my computer and searched for drivers and told me it was ready to use. I then inserted the CD in my computer and the program ran and now I am going to be able to work a part-time job from the comfort of my home. Thanks Amazon and D-Link!

I have an Atom-based motherboard with a single built-in network interface. I needed to add a second network interface so that I could turn the machine into a router. This device worked perfectly for my needs. I'm running Ubuntu Server 10.04.3 and it was detected correctly and works perfectly. The connection has been rock solid for about a month now. The 100mb speed wasn't an issue for me since it's still faster than my DSL connection. Very pleased and highly recommended for Linux users.

We've used at least fifty of the previous item with this model number. They work.I ordered one of these since I needed another. It never worked. Tried on Linux, Windows 7, Windows XP. I think that we got winxp to notice it. However, it never was more than an entry in the USB table.In short, defective.Now, I read a lot of reviews on Amazon that say the same thing. Does this mean that there is terrible quality control (since the basic item works so well), or does it mean that Amazon keeps sending out the same defective one that gets returned.Maybe one of us should mark the defective one when we send it back to Amazon. Then, the next guy who gets it would be able to tell that he was just sent an item someone else determined was bad. Just a thought.Of course, it could be the manufacturer just has bad quality control. Maybe they should step up. Of course, if you go to D-Link's website, good luck finding this item. They really don't want to be selling these.

Works great with my 2nd gen 11" Macbook Air. Since I use my MB Air as a desktop at home, plugged into an Apple Cinema Display, and a USB hub. This Ethernet to USB adapter speeds up my connection through my home network. Simply plugged it in and it started working right away.The only setup needed for me, was to change the priority of the network devices in the System Preferences, so that when plugged in, the USB would be prioritized over than the WiFi.I would not recommend it for portability as it was a bit larger than I expected (about four times as big as the Apple brand adapter). However for home use it worked out great.

I bought this to use on my Mac Mini after thinking I was having problems with the Apple USB Ethernet adapter I was using. (Turns out it was some other problem, but oh well.) Anyway, this worked great on the Mac, no drivers needed. Just plugged it in and configured it. My only complaint would be that it is a bit bulky.

New In the box, I like these adapters, they work well for testing and use. I am an electrical engineer and work in factory automation and control. You can take a 4 of these mount them in a cabinet connect them to a hub load the driver on a server and have 4 more IP networks without shutting down a server to install more ethernet cards. Or having to reconfigure server software.

This product was sent out to me in a timely manner. Once I received this product, it came with very simple instructions, was extremely easy to install, and once installed was ready to use with nothing further required of me to use it. Overall, I believe that it was a great product and worth what I paid for it. I would even say that it is worth more than I paid.
