How to increase target capacity?

Hello!
I have bought Wi-Fi the adapter TP-LINK TL-WN7200ND, but its target capacity is lowered, from for regional restrictions in my country.

Whether it is possible as нибудь to lift target capacity of the adapter with 20dbm (capacity at present) to 27dbm?

The adapter is collected on the basis of chip Ralink RT3070.

sir you need to contact with some one expert their, in the forum no one can guide you about that,

thanks
