how did you setup your mangle? did you set your game ports priority?

yes sir I did it, but latency still high

No answer at all ? Need advice to solve this

The reason you did not get much response is you did not make your researches and did not ask specific questions.
"It does not work please tell me what to do without making me educating myself at least a bit" is not what encourage people to help.

WiFi for gaming is a bad idea in general and should only be used if there is really no other way. The air is a shared medium by nature, whereas a cable connection is dedicated.
If you still want to use WiFi you want to inform yourself on multi SSID setups, channel distribution and especially WMM. Checkout what is usually done for VOIP over WiFi. You need something similar for your game traffic.
If you are not ready to do so, MT is the wrong device for you.

In that case, go for one of the commercial "Gaming WiFi Routers", Yes, they are more expensive, but I think you just discovered the reason for that: They do not need you to know your stuff.
