What router do you really need?
Most Internet Service Providers (ISPs) will give you a modem-router to get you online when you sign up, and many to these come with Wi-Fi built in, making it easy for you to get online or shuttle files around your home without plugging in.
The problem, sometimes, is that some of these free modem-routers offer only basic functionality and may not always work happily with your Mac. So, features such as Back To My Mac may not work as expected, for example, and the Wi‑Fi network that’s broadcast may not support the faster 802.11ac protocol that the latest Macs and iOS devices are capable of using.
Tune in to better Wi-Fi
The antennas in 802.11ac routers, such as the Linksys EA7500 Max-Stream AC1900 (£150, amzn.to/1OYw4tN) support beamforming, which enables your router to actively direct Wi-Fi signals towards your connected 802.11ac device, making a reliable and robust connection more likely.
The latest AirPort Extreme is a great example of this. It contains three internal antennas for broadcasting its network in the 2.4GHz band and another three for simultaneously broadcasting in the 5GHz band, helping your devices to latch on to the best one. Most third-party routers use external antennae for the same job.
Also consider how many people in your home or office actually need Wi-Fi access, and whether you want to be able to share other devices; AirPort Extreme’s USB port lets you can share a printer or storage, too.
