Bcz now is holiday, many of my relative come to my house and use my wifi. These made my dota 2 become spiky and laggy. The ping boost up to 400ms, ussually its 15ms...

I want to use QOS to priority my connection. But the setting of my router is so "abnormal" compared to other router.

Can anyone help me to fill them up o.O?

i only know that the dota 2 port is 27015-28999 and my computer port is 27005.

My lan network is 192.168.1.0 255.255.255.0.

Below is the screenshoot of my router's QOS
