Qualcomm Atheros ar5bwb222 wifi card delivers extreme game lag

Hello fellow members, I have been experiencing this problem ever since i bought the PC.

When I am playing a video game, I experience fine ping(less than 80. But I am teleporting back to where i was 5 seconds ago or everything on the screen freezes and I can only move my head.
Games I have tested so far: BF4 Beta , TF2 and Planetside 2
All games run smooth, but with the teleporting issue or freezing in game

I am currently using a USB adapter to solve the solution ( it runs fine, so its not my ISP nor router)
But I would like to use the wifi card as it is faster. ( Speedtest.net testing)

This problem only occurs in games, internet and testing showed nothing wrong. Windows is saying the wifi card is fine as well.

I have updated my drivers to the newest one available (10.0.0.256) Downloaded unofficially because gateway has the original drivers still last time I checked (From Atheros.cz or something like that) Problem is still present with the original and new drivers.

If anyone has a way to solve this, please tell me ASAP. Thank you

I fixed it! All I had to do was use windows to diagnose

Nope, only reduces the time it takes to lag
