Up until 2 days ago I was able to screen mirror by connecting to my Roku without using Wi-Fi. The significance of two days ago is that is when I was trying to use my phone's hotspot to connect my PC because my internet was temporarily down. And doing so I must have changed a setting or two and now every time I select screen mirroring my Wi-Fi automatically starts up. this is a problem because the part of the house that I'm trying to screen mirror in does not have a good Wi-Fi signal. If I let it connect and then turn the Wi-Fi off, it turns the screen mirroring off as well. Does anybody have an idea of what setting I may have changed?
