The Q60T 4K TV is only getting 26 Mbps down over WiFi on our gigabit speed fios using a Nighthawk router. Speed tests were no better on wired connection (20 Mbps down). In comparison, other WiFi connected devices got speeds well above *300Mbps* up and down. The Samsung Q50R did the same thing and we brought it back thinking it was defective. Internet research seems to have no answers. Is there any solution to this issue? Please help!
