I'm not able to stream anything in HD without buffering. I've also experienced some minor connectivity issues on my new PS4 as of late too (party drops, could be PS4 isolated).
Setup: Motorola SB 6141, Doc 3.0 - Asus AC66R
Here's my results all with the same device taken in the same exact room that the router is located.
Router 2.4ghz band
Router Hardwired
Motorola SB6141 Hardwired directly

The "Mason HP" is the laptop I was using the test
I just recently updated to Merlin's latest file RT-AC66U_3.0.0.4_374.35_4
Have had issues since, and even before that sometimes while running the latest official Asus firmware
Any insight?
Thanks
