Fenvi bcm94360ng 5Ghz slow speed

[Rok Murn]

Hello, Im using Fenvi bcm94360ng card in my 7590 and 5ghz (40mhz max) speed is capped at 200mbps and there is no country code. Using the AirportBrcmFixup kext i was able to get 5Ghz (80 mhz) but speed is still not rated 800mbps.

Any help is appriciated.
