I dont understand what you are asking?

Tere are 32 different MCS (modulation coding schemes) in 802.11n. The data rate shown on your laptop depends on a lot of factors.

Security if you dont use wpa2-aes or open then you only see legacy data rates.

If you have a long guard interval you get 130Mbps

It appears you are only seeing a single channel with short gaurd interval MCS 15.

If you have 40MHz wide bonded channels it may be the client capabilities.
