1. Android 安卓 Google Play 下載 Wi-Fi 分析儀
2. 掃描目前 Wi-Fi 環境現況, 查看您的Wi-Fi目前頻道。
3.以下圖為例，頻道1~3目前就佔有三個Wi-Fi ，其中2.4G WiFi AP 訊號最強。別以為家裡訊號最強就沒事了，三個Wi-Fi的網路訊號都會受到彼此干擾
所以播放影片或是傳送文件速度也會變慢，要怎麼改善問題？這時就要手動調整您家裡的路由器頻道了。

3.打開後開啟Airport APP 按下首頁右上方的「Wi-Fi 掃描」- 「掃描」
4.等待約兩三分鐘後即可停止掃描，如下圖所示越往下的訊號越弱，RSSI是強弱的數值。
5.接著點擊畫面右下角的 i 進入 頻道用量 畫面，可參考數據將Wi-Fi調整至裝置少的頻道，讓家裡網路順暢一些喔！
