Didn't work for me even after watching several times. Then by just messing around I discovered the missing step is to select the little nut icon in the upper right. That takes you to the Wifi page to enter our wifi info. Whew. Just goes to show when someone already knows how to do something and tries to teach someone else it's not uncommon that they forget to tell you something (like poor teachers) and then you think you're dumb! No, it's the teacher, not you. Be well.

I will try to do that
