1.git clone https://github.com/oblique/create_ap.git
2.cd create_ap
3.sudo make install就這樣安裝好了
4.接下來安裝依賴庫sudo apt-get install util-linux procps hostapd iproute2 iw haveged dnsmasq
5.就這么簡單幾個命令就能安裝好全部環境
6.接下來保證你的網線插在pi3上並且能上網就行了。輸入下面的命令啟動無線AP：
sudo create_ap wlan0 eth0 熱點名 密碼
接下來就去打開手機wifi看看有沒有上面命令中設置的熱點名吧，有的話輸入密碼即可連接上，enjoy your PI3 wireless AP！
可以把上述的啟動命令添加到/etc/rc.local就可以開機自啟動了。
是不是很簡單，這個AP的局域網無線傳輸速度居然比我原來那個老AP還快一倍，也算是驚喜了，從此我的樹莓派3又增加了一個功能。
