In an age where WiFi is becoming a part of daily life, it is good to know that not all computers have WiFi built in. Even if some of these computers do have a wireless internet connection, they might end up suffering from lag over time especially if they are at least over a year old. And it goes without saying that laggy Wi-Fi is a big problem whether you are playing highly competitive online games or streaming on-demand music, TV shows and movies.

It is for these reasons above that you will need a WiFi adapter that can be plugged onto the USB port/s of your laptops or desktop PCs. A WiFi adapter provides a faster WiFi internet speed in place of LAN or built-in WiFi connection. In addition, its plug-and-play convenience means you can remove it anytime when not needed.

With everything said, Amazon has some of the best WiFi adapters for your laptop or PC that help boost WiFi connectivity. Here are eight of them:
