I am a Mac user who is trying to help my mother figure out an issue with her Compac. Talk about blind leading the blind. Anyways... a few days ago, her internet stopped connecting.

I was on the phone with a tech guy at Mediacom & after he had me perform many steps, he said the problem is found in device manager and Network Connections Sharing Center.

When I go to Device Manager, there is only one item listed & it has a yellow triangle with a ! The guy who was trying to talk me through this had me try to delete & reboot- no luck. Any insight would be greatly appreciated!
