I have 1 gigabit supported internet bundled with my rent, and I need to buy my own router and modem that support and take advantage of the 1 gigabit network. What router and modem or combo router/ modem would you recommend? I'm looking at the Motorola MG7540 and MG7550. Will either of these suffice?
