Computer kicks everyone off of the Wi-Fi

[BatSloth]

Me and my friends put together a PC for our other friend. He has been playing on it since Christmas with no problems, but here recently when he gets on TeamSpeak and PUBG while his dad is playing the XBOX, the Wi-Fi just kicks him and everything else except his own PC off of the internet.
