Many have issues achieving the speed.
Client hardware plays a role too to achieve the speed.
You want amazing WiFi speed. .change your router...there is a reason why in the market they have wireless router which cost more than 2K...if a RM200 router can give u gigabit WiFi...what's the point of manufacture selling those high end wireless router and wireless cards.
So far the bes I've experienced is Killer WiFi..
