One of my bugbears is the widespread overuse of Wi-Fi. While Wi-Fi is convenient, there’s generally a price to be paid in terms of performance. Wi-Fi is responsible for a substantial proportion of broadband problems. I strongly recommend that, when you have devices that do not move (such as a set-top box or TV), connect them with an Ethernet cable rather than via Wi-Fi. As well as improving performance, you will potentially free up Wi-Fi spectrum and capacity that can be used to deliver better performance for mobile devices that do need Wi-Fi, such as tablets, laptops and mobile phones.
