Your Wi-Fi router is the unsung hero in your computer setup. It’s probably the thing you think about the least -- and in many ways it’s the most important link in your electronic chain. After all, your router is what keeps your iMac, MacBook, iPhone, and iPad connected to the internet, not to mention all the other stuff you’ve got sipping bits, like game consoles, TiVo boxes, and internet radios. Apple’s latest AirPort Extreme and Time Capsule are essentially minor updates, but if you’re a Mac user in need of a new router, both are extremely good options.
