I am not sure what's wrong with my Roku as it isn't connecting to WIFI. There is no problem with the internet as other devices connected to it are working. Do anyone came across this scenario? If so, what were the fixes you carried out?
Yes. I, too, have faced this problem on my Roku TV. Every router has a device limit. If you have exceeded the limit and intend to connect the Roku to WiFi, you can't do it. This is the main reason for the Roku device not connecting to WiFi. I am sure you can resolve this problem by disconnecting the WiFi on other devices that are not in use. Then, try to connect the Roku to WiFi again. If the problem continues, try moving the router closer to the TV or restarting both devices. Then, connect the Roku TV to WiFi.
