Description

I have an Linksys e8450 with mt7915 up and running. The AC performance is in general very good. If I am very close to the router I can receive up to 650 Mbits/sec and send up to 600 Mbits/sec. As soon as I move a bit further away the sending rate goes dramatically down. About 5 meters away RX on my MacBook Pro (AC2x2) is still 450 Mbits/sec, while TX goes down to 170 Mbits/sec.
Is there anything I can tweak? With my old R3P (mt7615) the TX performance was always better than RX, so I am wondering whether its the mt7915 driver/hardware limitations or anything in the settings I can optimize?

Research direction

Start by reproducing the reported TX/RX difference with the Linksys E8450, mt7915, and MacBook Pro at the stated distances. Compare the behavior with the older R3P/mt7615 and review available wireless settings; done means identifying a driver or hardware limitation, or a concrete setting that improves TX performance.
