Mirroring Android to Roku

[Android Central Question]

I'm trying to mirror my phone to my Roku TV, but my Android won't let me have the cast & Mobile hotspot on at the same time. It worked once,but when I tried it again, it just kept shutting off the cast & vice versa.

Mirror to Roku requires the phone and Roku being on the same WiFi connection. Mobile Hotspot requires the phone to generate its own WiFi network. The phone can't generate a WiFi hotspot AND connect to another WiFi network at the same time and if the phone is generating the WiFi hotspot it can't cast to a device connected to that hotspot.
