Question Wifi issue with firestick plugged into a ruko tv

Dec 30, 2020
I just got a new rca 4k roku tv, I am using a 4k firestick. But for some reason the wifi signal is less then 10 mbps. My plan is 500 mbps. My wifi signal on my phone is over 100 mbps so I know it's not a wifi problem. I had the same firestick plugged into my sony 1080p tv and got amazing wifi. Is it something with the roku I need to fix? Because the wifi on the roku tv has bad wifi signal too? Please help. Thanks
