TP-Link Archer – Compact Design
The TP-Link Archer is the last to be featured on our list but not the least. It features Nano design, making it incredibly tiny and easy to fit on any laptop. This adapter is so tiny (18.6 mm x 15 mm x 7.1 mm) that you could just leave it in the USB port of your laptop. It will not block any of the adjacent ports.

How To Select A USB WiFi Adapter

We made this list and selection based on several factors such as the size, the range and the speed. The design is another important factor. But that will depend on your personal taste. We are now going to outline what you need to consider in terms of the former 3 factors:

  1. Size: The Size of this is perhaps the first thing you want to consider. There are all sorts of sizes available in the market. Some such as the TP-Link Archer are tiny and easy to carry around, whereas others like the Trendnet AC1900 are much bigger but offer more power. Furthermore, the big ones are often packed with interesting features such as beam forming technology.
  2. Range: The Range of it is another important thing to consider before purchasing one. Most of us use a WiFi adapter to boost the connection. But there are times when the router is simply too far away and your laptop can’t pick its signal at all. Here’s where the range of the adapter comes into play. Some of the best adapters available today offer a range of over 100m.
  3. Speed: This is the reason most of us need a WiFi adapter to begin with. Most of the times, even when our laptops are connected to the WiFi, the connection is simply too weak. What this results in are slow loading pages and a stream that keeps buffering. (Frustrating, we know!) A good adapter can offer a speed of around 300Mbps. A really good one will go as high as 1200Mbps or even more. You will of course have to first ensure that the actual internet bandwidth is high.
