Question: Need to know if this adapter works with the Surface RT running on the Windows RT 8.1 O/S? I purchased a Belkin F4U047 adapter from Radio Shack and it doesn't work.
Document: Product worked as described. I had initially purchased a USB 3 USB to Ethernet adapter, but it did not work with my Toshiba U925T. I ordered this as I travel and I need an Ethernet plug to connect to some networks.The seller sent an email with links to the latest drivers as soon as the product shipped, but guess what? I did not need it at all! When the product arrived (1 day BEFORE delivery estimate), I just plugged it in and Windows 8 installed its drivers automatically.
shame on Microsoft, they have deliberately dropped support for the Surface RT to work with ethernet networking. there are third party manufacturers that have devices that work just fine, but Microsoft has apparently forced them to remove their products from the market. If you Google windows 8.1 rt ax88x72a, you will get the latest info.
I purchased this item because there is no RJ-45 port on the Microsoft Surface Pro and I needed a high-speed way to move lots of network data to/from the computer. It works flawlessly and allows transfer speeds up to 17 MBPS when plugged into the USB3 port. I did not need to download the Windows 8 driver for it; Windows 8 recognized it instantly. I have been very pleased with the thruput and convenience that it provides.
For some reason my on board LAN adapter stopped working without any notice or reason. Was going to get a PCIE Network Adapter but saw this on Amazon and I have a few USB ports available and thought I would try this as it seemed very easy. I am using Windows 8.1 and did not need to install any drivers for it to work.Before I got my product I received an email from the seller on how to download the drivers on my computer.
I need to network my new Microsoft Surface RT when there's no wireless available. But, Windows RT does not offically support hardwired adapters (or installing needed drivers). Luckily, this is not true. The URL in the first comment (Amazon only allows web pages in comments) provides instructions from the manufacturers on how to install the needed driver in but seconds. And then, this thing works great (at a great price).
Shortly after I ordered this adapter, I received an email from Plugable Technologies Inc. with a download link for the device drivers which I installed prior to plugging in the adapter. So far, I've used this adapter with both my Lenovo Ideacentre Horizon (Windows 8.1), and Surface Pro2 (Windows 8.1 Pro) with no issues whatsoever.
I didn't need to download drivers for Windows 8.1; it just worked. This adapter is simple and easy to use.
Plugged this into my Microsoft Surface Pro with Windows 8.1, and immediately connected to my network. Works like a charm.
If your a portable laptop kind of guy, then this version might be just a bit too bulky. on the other hand, if your a desktop owner in the need of a good converter, then I recommend this completely. Glad I picked up this product!P.S: The driver name from windows is not the name for the product itself, just thought u should know.
There seems to be some strange, supported, then not-supported, now supported history with this adapter and the Surface.What I CAN say is that my SurfaceRT with 8.1 recognized and works fine with this adapter. However, I DID have to make one small change in order to use it.
Answer: It is possible that you will need an update for it to work with windows 8.
