I'm looking at getting the AC68U. My main need is streaming video and internet access to the living room. There, I'll need a device that I will hook to a switch and then feed the HTPC, TV, DVD, etc. with cables from the switch. What device should I get for the living room gear? I'm not clear (I've read and read) on whether I need an access point, another router or what? I know I don't want (or need) a range extender because I understand that will reduce my connection speed. Any comments and help would be appreciated. Specific brand and model advice would be welcome. Thanks in advance folks.
