A router by itself isn’t the most exciting piece of technology. It’s utilitarian. But when it’s the odd one out in a column devoted mostly to laptops and desktops, it’s a welcome change. And Linksys’ N600 app-enabled router isn’t that boring to start with. It’s got simultaneous 2.4Ghz and 5Ghz band support, as well as 4 Gigabit ports at the back. And the “app-enabled” part means it’s ready to connect to the cloud and back your files up. Normally selling for $119, it’s a ridiculous $42 now after a $77 rebate.
