A:Answer Yes, you can configure this unit as a wifi hotspot and get all the additional features (including dual band) not available from your unit from AT&T. One word of warning: this does not support more than 100 mb/s on it's inbound WAN port, same as your current unit. It says it supports gigabit speeds, but that's only between devices connected to it, and does not apply to the incoming speed from your ISP. So if you ever upgrade to higher speeds from AT&T (or any other provider), this will be a bottleneck for any wired or wifi devices connecting through it.
