Seller DBROTH: https://www.amazon.com/sp?seller=A2LM6ZPY06LT1N is placing returned items back into the outbound new shipments, WITHOUT INSPECTING THEM.
It came in a reasonable amount of time, but I did not need it immediately. I placed the unopened box on a gear shelf and left it there for a while. When I opened the box, I noticed the ALFA sticker on it had been previously unstuck (see attached photo). I thought maybe I got an open box product by accident, this happens (it shouldn't). I am usually happy as long as the product worked. SPOILER: It doesn't work.
After opening the box, however, I realized this was not only open-box, and used, but it is physically broken! The rear serial number sticker/warranty sticker is pierced to reveal the assembly screw, which means this product has been taken apart. Inspecting the plastic seams on the side reveals gouging from a tool to disassemble forcefully. Inserting the USB cable wobbles nearly 30 degrees of angle. I finally plugged the device in and there is no power light and nothing shows up in device manager. I also tried a mac and linux computer and it is completely dead.
Don't let yourself be in a similar situation. 1. Don't select DBROTH as the seller for any of your items. 2. Immediately check your packages when they arrive.
AC1900 supports 5Ghz so as expected the speed is better at close range. However, it does not justify using a bulky device just for that purpose. Maybe for desktops it might be justifiable but in that case I would rather use Ethernet cables.
The device works with windows built in connection manager. The included software also works but adds little functionality. For example, you cannot keep 2 connections using separate hardware (internal wireless card and Alfa) simultaneously . The wireless internet sharing works but not better than window's internal manager.
My biggest grievance is incompatibility with R36. R36 and the previous generation was an excellent combination solving the problem of redistributing the connection over a long link. I hope Alfa makes R36 compatible with AC1900 via a firmware update in the future.
Overall, the product works as advertised. I am not currently using it but keeping it.
I had to completely uninstall the drivers on the enclosed cd and download Windows 10 drivers from the chip makers site. Then I plugged in the adapter and let Windows discover it. Before anything else I went to device manager and updated the drivers using a manuel search to the drivers I had downloaded.
UPDATE... The adapter is still performing better than hoped for. I did have an issue as it occasionally would disconnect. This was solved by going into the advanced configuration and unchecking the ability of the adapter to turn off the computer.
I found the best performance on the 5G network. Even 2.4 performance is superior to my on board laptop adapter. This is a five star item hindered by very poor installation for Windows 10.
