Computer troubles

My cousin phoned me while ago to asked if my brother is at home. She has a problem with her computer and asked my brother if he can fix it. My brother was still at his work that time and I told her that I will just call my brther to drop by at her place after his work. When my brother came home I asked what happen with our cousin's computer. He said just a quiet problem with the its CAT6. The computer is already good functioning and our cousin can continue her pending work.
