These sometimes complicated, often frustrating devices allow sharing a broadband Internet connection among computers and gadgets, provide a way to create a network for sharing data between users and machines, and of course, give wireless connectivity for iPads, smartphones, media players and other types of technology hardware. With so many wireless routers available on the market offering so many
different features and advertised speeds, selecting the right router for a home or business can be challenging. On top of the problem of just selecting a router is the complexity of Wi-Fi technology itself. Wi-Fi is a tricky beast and subject to so many varying factors and environmental fluctuations. If there are many other wireless routers in your proximity, you face potential signal interference, especially on the more crowded 2.4 GHz band, a frequency that wireless routers use to transmit and receive data. Certain building materials, multilevel homes, glass partitions and household devices that operate on the 2.4 GHz frequency like microwaves, baby monitors, and cordless phones can all degrade wireless performance. Businesses often spend thousands of dollars to hire wireless networking professionals to perform site surveys to determine the best equipment and means to deploy a wireless network. It is small wonder that home and small business users who may not have these professionals at their disposal can feel frustrated about purchasing, setting up and maintaining a wireless router and their own wireless networks! To add to the confusion, routers manufacturers now offer a new generation of wireless routers. These routers feature the latest 802.11x technology; 802.11ac—a step up from, 802.11n as it offers higher throughout speeds and better range. Sounds great, but does 802.11ac currently deliver any gains over 802.11n? Do you need a lesser expensive single-band router or a more expensive dual-band? Do you need to upgrade or purchase an 802.11n router? Does a higher-end router mean better Internet connectivity? What about IPv6—is it best to get a router that supports IPv6? These questions as well as factors like security, parental controls and extra features such as the ability to connect USB printers and external storage drives to a router for sharing in your personal network, are all considerations to weigh when deciding to purchase or upgrade a router. It's best to get familiar with what you in particular need from a wireless router before you shop rather than relying on anecdotal customer reviews on websites such as Amazon. While you can get a general feel for other customers' experiences with a particular router, Wi-Fi is so fickle and performance can vary from one home to another. Just because someone had a terrific (or miserable) experience with a particular router does not necessarily mean you will have the same experience. Professional reviews in controlled environments, like those I perform in PCMag's labs, are a better source for help in deliberating over which router to choose.
