Here is my test result, i achieved this performance in my room, but i think this is very nice performance:
There is a wireless connection between the devices, and running OSPF between them.
Proftp running on my Ubuntu 12.04 server, so this speed is 158 Mbit/sec TCP speed, and CPU load is around 60%.

Yes, It is possible with NV2.
It is even possible to reach 200 Mbps.
you have ROS 6.11
Try to upgrade to 6.12 also with wireless-fp package and repeat test.
What is wireless-fp package ?
It’s new wireless package with capsman.
I will try out
I tried with new 6.14 and with new wireless package, the speed is the same.
But i think this is perfect.
I am using new wireless since 6.12 and it works fine for me. I am not going to use capsman soon as it is still not boiled well.
