「Wi-Fiミレル」は、ご自宅やオフィスなどのWi-Fi環境を計測することができるアプリです。 現在接続されているインターネットの速度、Wi-Fiの速度を数値やヒートマップで“見える化”することで、より快適なWi-Fi環境を実現するお手伝いをします。 光回線などのインターネット側の速度とWi-Fi通信のみの速度とそれぞれのスピードがわかりますので、Wi-Fiの速度が遅いなどのお悩み時に回線の問題か、Wi-Fiルーターの問題かの区別をつけるときに大変便利です。 弊社Wi-Fiルーター以外をご利用の場合でも、本アプリを使って計測することができます。 ・速度測定 インターネットのダウンロード、アップロードの速度と、Wi-Fiのネットワーク速度を計測します。数字が小さいほど遅く、大きいほど快適であることを示しています。 ・ヒートマップ 場所ごとにWi-Fi速度を計測することで、ご自宅やオフィス全体のWi-Fiの速度をわかりやすく把握できるヒートマップを作成できます。 間取り図も読み込みできますので、場所ごとの計測結果が一目でわかります。 ・Wi-Fi情報の表示 現在接続しているWi-Fiについての各種情報(SSID、IPアドレス、サブネットマスク等)を表示します。 また、ルーターの設定画面を開くことができます。 ※以前は電波強度測定機能もありましたが、iOS16以降利用できなくなったため、機能を削除しています。
