Answer 1

Your design is failing due to a common misconception with WiFi speeds. With 802.11n the number 300mb/s is the link speed, not the actual bandwidth available for user data or even the IP layer. The effective bandwidth is closer to 40mb/s best case, have a look at the FAQ on SmallNetBuilder.com that discusses this in further detail.
