モデムデバイスは、ルーター本体を完全に断電してから通電させないと、認識しない
※M.2スロットの3.3 V電源ラインはカーネルから制御できず、PCIeリセットピンも露出していない
PCIeモードでは、ATコマンドは送信出来ない

あとがき
-
BPI-R3より、色々進化している
-
ハードウェアアクセレーターは有効
-
Wi-Fi7はまだまだ成熟していないが、逆にどんどん良くなるのが面白いかな
-
購入について、AliExpressが一番安いが、アフターサービスを考えると、Amazonやエレファインの方が安心かもしれない
-
モデム動かすのに、丸１日掛かった。。。
-
Wi-Fi BEはまだ不安定だが、AXの完成度は高い
※BPI-R3より早いね (アップロードはWANチューニングの問題)
-
BPI-BE1900 なんだか値が張りそうな気がするが
-
AdGuardHomeとWebminのメンテついでに掲載した
-
AW7916-NPDを換装してみた
BPI-R4-NIC-BE14より気持ちSNRが良い程度
ボード側の方に問題がありそうだ
このBPI-R4は文字通り机上の検証用だね -

mloが動いた！
が、しかし、、、(6GHz + 2.4GHz)
もとい、、、 (6GHz + 5GHz)
DFSで2Ghz掴んじゃうと、なんかおかしい？
