Very attractive pricing! I'm kinda new at SME products but consumer ones just don't cut it for me anymore.

I want to ask:
What is the advantages RB2011UiAS has over RB915 ?
Does it support DHCP out of the box ?( read somewhere guy was having problems configuring)

Want to pull the trigger but kinda noob so need some after sales support. I'm assuming I still need the TM junk to act as a modem ?

Nothing crazy just home use <15 devices. My goal is streaming 1080 from a nas wirelessly.
