2つのSSIDを設定しようとしていますhostapd。私ができることの1つは2番目に不可能であることが証明されました。
私の最近の仮説は、最初にその中に現れる他のものを作成し、それをファイルに追加してからip a使用する必要があるということです。私が思いついたコマンドと現在経験している問題は次のとおりです。intefaeshostapd.conf
# iw dev wlx00e032800384 interface add ap2 type managed addr 02:e0:32:80:03:81
command failed: No such device (-19)
アダプタはeBayで安く購入され、rtl8821CUドライバは動作しています。
アップデート：設定hostapd
hostapdそれ自体は同じことをしようとしますが、同じ理由で失敗しているようです。

答え1
Wi-Fiカードでサポートされている場合は、物理インターフェイスに2番目の仮想インターフェイスを追加する必要があります。使用しているiwコマンドは、仮想インターフェイスに2番目のマネージドインターフェイスを追加しようとします。最後に、phyに接続された2番目のAPインターフェイスが必要です。カードにMACが残っている可能性があるため、MACを割り当てないでください。
iw phy0 interface add ap0 type __ap
"__ap" には 2 つのアンダースコアがあり、ap0 は仮想インターフェイスのランダムな名前にすぎません。
