一樣是懶人用結論

2.4G開11n之後非常地不穩定...
就算緊鄰放置可以瞬間衝上150M的理論頻寬，有時候掉到剩下5.5M
實測數據有時候比只用11g還糟糕(11g整體上穩定)

相對來說，5.2G在低距離就很穩定的跑在270~300M，低也不會低於150M
如果限制20M頻寬(最大速度144M)，有時跑得比40M頻寬還快...

但是個人很大程度的懷疑很多特性跟100M有線網路阻塞嚴重有關

整體來說最佳的設定方式是
2.4G(自動頻道) 802.11 Mixed(g/b)
5G(自動頻道) 802.11n only 20/40MHz


==========================================================

將來源&接收端都改成100M Full
2.4G則啟用11n模式
