To compliment your high speed wireless modem router, TP-LINK have launched the Archer T4U, a wireless Dual Band USB adapter that supports both 5 and 2.4Ghz bands plus high speed USB 3.0 connectivity for additional performance. Best of all, the installation process is flawless and you’ll have a wireless connection up and running in no time, even if you are the computer novice.

T4U Product highlights

  • Dual Band (5 & 2.4Ghz)
  • 867 & 300Mbps Wireless Speeds
  • USB 3.0 Port


Although all laptops support wireless, these are generally limited by its specifications which is where the Archer T4U comes into play. By connecting this product to a laptop or standalone PC, it gives the user high speed wireless access of up to 867Mps. This means that your streaming of movies or online gaming will be considerably faster than the norm.


  • Supports 802.11ac standard- The next generation of Wi-Fi
  • SuperSpeed USB 3.0 port—Up to 10x faster than USB 2.0
  • Dual Band connections for lag-free HD video streaming and gaming
  • Maximum speed up to 5GHz 867Mbps or 2.4GHz 300Mbps
  • Backward compatible with 802.11 a/b/g/n products
  • Supports ad-hoc and infrastructure mode
  • Easy wireless security encryption at a push of the WPS button
  • Supports Windows 8/7/XP 32/64bit
  • Easy Wireless Configuration Utility
  • Equipped with a USB 3.0 1.0m Extension Cable for flexible deployment

To install the Archer T4U, you simply connect the product to a spare USB port, preferably a USB 3.0 port and away you go. The product also comes with an installation CD to assist in configuring the USB adapter to your network. I was also pleasantly surprised that the adapter came with a USB extension cable that allows you to connect the item to the back of your PC.

When I connected the T4U to our desktop machine, Windows 7 did not automatically detect the item nor install the appropriate drivers. As a result, we had to use the mini installation CD to assist in connecting the adapter to our wireless network. One strange aspect about the installation is that it took a while for the installation program to run. We tested this on two machines and the same thing occurred… I guess patience is virtue!

The installation also gives you the choice of just installing the driver or both the driver and utility.



Once the installation was completed, the utility displayed the networks that were available to the adapter that included both 2.4 and 5Ghz bands. To connect, you simply click on the network and then enter your security key. Installation could not be simpler!

In terms of the wireless connection, we could access our wireless network quite comfortably of up to 25 metres with minimum connection loss. The wireless did start to drop in speeds when we got more than 10  metres away but even so, it worked remarkably well through walls. We got full speeds of up to 5 metres with a small loss at the 10metre mark. Even at 25 metres away from the router, the T4U performed quite well that most users would not notice the slight drop in performance.


The product does support WPS (WiFi Protected Setup) via the utility tool and also profiles and an advanced feature. The advanced feature allows you to slightly tweak the T4U, whereas profiles are your wireless networks.
