NKBMobile のメモ: obs600-09 GW-US300MiniSでAP化

無線LAN USBアダプタをアクセスポイントにすることが、可能となっている方がいらっしゃるようなので、同じようにやってみました。

おおもとのネタは、http://wireless.kernel.org/ から頂きました。前回のDebian環境 kernel 2.6.36にて試しました。

(1) make oldconfigでの表示
初めは、linux-2.6.36/ツリーにカブせて、make oldconfig しようとしました。「Support for 802.11n」にて 11nサポートも始まりつつあるようです。しかし引き続きmakeすると、とてもうまくいきそうにないのでこれは断念します。

無事にhostapdで "handshake completed (WPA)"が出ており、deannaにWifi接続良好です。hostapd起動後6時間くらいスマホ3台接続して様子をみてますが、問題なくWifiネットワーク動作しています。さらに次は、手持ちの無線LANのUSBアダブタで他にも動作するものがあるか試してみたいです。
