@MrXs-spiritgen7 If that guy has a router then I don't think that most of his communication will be UNICAST. Although it could be because of this too. I'll ask my IT head.
Take a full breath; hold if for one second. Then, with your mouth open, blow out as hard and fast as you can. Your lungs should be completely emptied – meaning that you can blow no more air out even though you try– in no more than 4 to 6 seconds.
