I just replaced a Lynksis product similar to the N600 with the Netgear Nighthawk AC2300. Its a lil pricey, but not bad. However before my wifi speed would only avarage 50Mbps. I could stream ,but it was weak as your saying and would buffer due to the number of devices I had sharing wifi, with the Netgear my speedtest over wifi gets 120 to 130 Mbps. Big difference and worth the extra money. And that was with 8 devices sharing wifi at the time,, i sometimes have 12.
