It reads like you think you can control her feelings through your actions. "If I connect her Internet, she will feel loved."
You can't control how she feels. Maybe she will think that you think she's incompetent (as you said in this thread multiple times). Maybe she will feel smothered. Or trapped. Who knows.
I think that you have a LOT of expectations. That if you act like ABC, she will respond like XYZ. Your focus is so squarely on her.
As I asked above, if she has a problem with the Internet her first night away, is she going to call you for tech support? What about after a week. Or a month. Or a year. If any of those are "no" then why are you doing it now?
