[Yokuutsu]

The network works, they were at my house last night. My tablet, my mom's computer, everything else connects (including their phone) but not the laptop. (They're not over here right now, but I thought I'd try to find possible solutions....and they don't have internet at home).

It's wifi.
And I used the diagnosis tool Windows provides. It was useless....even used this one scanner that finds worms, viruses, etc....it found nothing.
