TCL ROKU tv has really slow download speed.

I have a 55R617-CA TCL tv with a ROKU TV model 7120X. For about a week now I have been experiencing very slow download speed. My internet is 75Mbps. All my other devices, phone, Amazon Fire Stick, PS4 and Surface Pro have tested between 60Mbps and 70Mbps. My TCL ROKU TV has been between 9Mbps and 17Mbps. All devices were tested in the same room on the same network.
