My older gen white macbook is connecting fine, my mom's newer gen isn't.

I'm at mom's visiting her for the weekend. She has free wi-fi in her building. Whenever I come over here with my computer, her internet doesn't connect while mine connects just fine. After I disconnect though, her's continues to not work. I'm guessing the landlord needs to reset the router, but I'm wondering if there's a way to keep this from happening in the future.

If she creates a new user account, does it connect using the new account?
