NANDへのインストール

USBメモリにファイルを準備

Firmware selectorから、ファイルを全てダウンロードします。

nand0.png

FAT32もしくはext4でフォーマットしたUSBメモリのルートに、ファイルをすべて配置します。

インストール

ディップスイッチを 1111 （全て上側）にして、起動します。最初は3秒でタイムアウトするので、↓キーなどを押してタイマーを止めます。

ディップスイッチを 0110 もしくは 0111 にして、電源を切り、再度起動します。

ブートメニューに [eMMC] と表示されていれば成功です。
このまま 1. Run default boot command を選択します。（時間経過でもOK）
メッセージの流れが止まったところで、Enterキーを押すとシェルが起動しています。

eMMCから起動すると、SDカードへはアクセスできません1ので、SDカードは抜いても大丈夫です。

動作確認

LAN側へ有線接続して、Webインターフェイス（LuCI）を見てみましょう。
初期のIPアドレスは 192.168.1.1 、ユーザー名 root 、 パスワードはなしです。

パスワード未設定なので、画面の指示に従って作成しておきます。

Screenshot 2025-08-29 16.44.04.png

起動できました。
ここまでくれば、（壊さない限り）SSHでの作業も可能なので、USB-UART基板を外して、蓋をしてアンテナを取り付ければ組み立て完了です。

アンテナ8本は圧巻ですね。

今のネットワーク周りは大変にカオスなので、これがどれだけマシになるか見ものです。

ファン

今回買ったキットには、PWMファンがありますが、OpenWRTのバグなのか正常に動作しないようです。
そこで、起動時にファンを動かすようにします。

System → Startup → Local Startup にあるテキストボックス`に以下を入力します。

echo 40 > /sys/devices/platform/pwm-fan/hwmon/hwmon1/pwm1

exit 0

OpenWRTの設定

次は、OpenWRTの設定をしていきます。

  • PPPoE
  • Wi-Fi
  • LTE
  • MultiWAN Manager
空き領域の拡張（失敗）

※諦めました

ディップスイッチを 1010 （NANDモード）にして再起動します。
