Archer T4U V2 AC1300 Wireless Dual Band USB Adapter
*My Test Setup
Windows 10 Pro
USB 3.0 Port
*Wired & Wireless Performance
I tested the Archer T4U V2 plugged into a USB 3.0 port on my desktop computer. I ran several speed tests with the adapter plugged in the USB 3.0 port by itself, and while using the included USB 3.0 extension cable. The extension cable had no effect at all on performance. Speed tests were the same with or without.
My Internet Plan: Download 75 Mbps / Upload 10 Mbps
2.4 GHz Speed Test: Download 78.51 Mbps / Upload 12.12 Mbps
5 GHz Speed Test: Download 90.37 Mbps / Upload 12.16 Mbps.
As you can see, those are great results. However, I have experienced an occasional brief loss of connection while streaming HD content, but for the most part, it has performed decently.
Note: When you first plug in the adapter, Windows will install its own generic driver. Before I installed the latest driver from TP-Link’s website, I was getting terrible results on the 5 GHz band. After installing the latest driver from TP-Link, the adapter performs much better. So for the absolute best performance, you MUST install the latest driver from TP-Link’s website.
The adapter offers decent performance, especially after the driver update. I do have concerns about it’s build quality, though. It’s made of plastic and doesn't feel very durable in hand. As long as you aren't frequently plugging it in and unplugging it, it should be fine. It would have been nice if TP-Link would have made it out of metal, or at least a harder plastic. I have USB thumb drives that feel better made than this. Also, it's too bulky to use in a USB port by itself when neighboring USB port(s) are occupied. Thankfully TP-Link includes an extension cable to remedy this. And some may find the bright, flashing green LED to be a distraction, especially in a dark room. Other than those few concerns, it’s inexpensive and performs decently.
