Mesh Wi-Fi systems have become a staple of the modern home, and small businesses have embraced them as well. In fact, they provide an excellent solution to a real problem: Wi-Fi "notspots". The Tenda Nova MW3 Mesh Wi-Fi System won't suit everyone; there are only two satellites instead of three, and it uses the slower AC1200 wireless protocol. Still, at just £67.29 (around £50 / AU$100) from Amazon, it's the most affordable mesh Wi-Fi system on the market, though you do have to factor in the cost of Plus shipping. Tenda says its system allows you to create a Wi-Fi network that covers up to 200 square meters and eliminate dead zones in your home or office. There's only one SSID and password to remember, which means moving from one area to another should be painless.
