  • N-6300を無線LAN親機(AP)として動作させてみる(再チャレンジ)
前回、N-6300を無線LAN親機(AP)にしてみようとして失敗。前回の最後に考えたこと。
①そもそもN-6300ってAPモード対応してるのか?
②カーネルコンフィギュレーションのPrism AP、有効にしないとダメ?

まず①。Intel N6300 wireless card doesn't support AP modeを読んだ。Wi-FiデバイスがAPモードをサポートしているかが重要みたい。次にソフトウェアアクセスポイント - ArchWikiを読んだ。iw listと打ち込むとAPモードに対応しているかわかるみたい。

iw listと打ってみたところ、APモードは対応してなかった...。というわけで、一旦仕切りなおし。先日購入した無線LANチップたちを試してみることにします。
