Internet Trouble

Hi, Im new to this site. Recently, I've been having trouble with my Internet. It just shuts down on it's own. Also, my Itunes do the same thing. When I reboot my computer i always have a system32/services error as well. My Internet works decent right now, I just don't want it to get worse. Here is my log.
