The TP-LINK Router TL-WR840N is a terrific option if you’re searching for a fairly affordable yet excellent WiFi router. In fact, most Internet service providers in Uganda use it as their default WiFi router. I decided to write a review of the router I received when I signed up for Liquid Home Internet, which included it in the installation equipment.

Over the years, I’ve used a number of routers. Back when 3G mobile internet was available, there were 3G USB dongles, MiFis, 4G LTE routers/modems from Huawei and ZTE, as well as traditional WiFi routers from D-Link, Linksys, and Netgear. In this part of the world, mobile phones and 4G MiFis are the main methods of internet access, making WiFi routers less common.

In contrast to other regions of the world, WiFi routers have primarily been found in offices rather than as common consumer goods in households. However, with the popularity of home Fiber and Microwave internet expanding, it is now important for African readers to focus on WiFi routers.

Given my needs as a power user, the TP-LINK Router TL-WR840N wouldn’t necessarily be my first pick for a WiFi router. However, this tiny puppy from TP-Link merits a place at the high table of networking equipment for what it is worth and because of its widespread use here. Its advantages are clear; for typical residential internet needs, it is an inexpensive and extremely reliable WiFi router.
