re: What router should I buy?

I did say that client to client can benefit from a better router. I guess my explanation was bad. Still, ac is overkill unless you are doing a lot of HD streaming from a lot of devices simultaneously. You can do full 1080p, 3D, with Dolby surround streaming with less than 20 Mbps.

Plus, most people that stream via Plex or something like that would benefit from hardwiring their devices anyway. 99% of people who ask for a router recommendation on this board would see no appreciatible difference from a N600 to a AC1900 router.

There are some exceptions, but most will never even use the N600 to full capabilities.
