MY wife has a mic 2012 non retina MBP. For the last few access points and routers this unit doesn't connect above 300 Mbps. So my question is what card is in this unit? And if it is indeed a 450 card what couldI do to try and get above this limit? Currently I have an Unifi Ac pro (2nd gen) Access point. I also have a nether R6300v2 for testing and neither has the MBP connecting at that rate. Ive tested different channels and even for testing stood 5-10ft away from the units just to see if it could be done. I'm aware if walls and other outside noise come into play then the link rate will drop. But I was hoping at some point i would see the connection tip above 300. O yes I have the 5Ghz set to 80. I believe IO read somewhere that Apple does't connect that high on the 2.4 band.
