I misread your post at first. I thought you were connecting one Roku device and two Roku TVs but now I think the two TVs are non-Roku models that you wish to have sharing input from your one Roku.
The Roku has only one output which connects to the TV via a direct HDMI cable. It has no provisions for outputting anything via WiFi.
You could run the HDMI output onto a 3-way HDMI splitter and then run separate HDMI cords to all three TVs, but all would receive exactly the same program. Plus these splitters sometimes have problems if the TVs don't all support the same resolutions.
Generally it's both easier and better for each TV to be connected to its own streaming device.
