My internet speed is a true 300-320 Mbps. My Fire stick 4K Max is getting 3-5 Mbps. I've rebooted both the router and the Fire Stick. Wifi connection. Tried both 2.4 and 5G. It's 3 feet from the router, a NETGEAR Nighthawk Wifi 6 capable router. It's not blocked by the TV, as used my phone's NETGEAR scanning app and it works fine when held right beside the fire stick, no significant decrease in signal. It is indeed in a wall outlet with the included power block. My phone is getting 300+ up and down, don't understand why the stick is getting damn near dial-up speeds.
