ubuntu10.04でGW-US54GXS

使えるようになったので作業メモ
- ただし、アドホックモードのみ。
- ドライバがマスターモードに対応していないのでアクセスポイントとして使うのはこの時点ではできない。

- Ubuntu日本語フォーラム / Ubuntu 9.10 でPLANEX GW-US54GXSが使えないを参考に。
- Ubuntu Edgy で無線LAN を WPA-PSK で使う - shag の日記
- Community Documentation - Community Ubuntu Documentation の "Network, wireless, and internet devices"
- NetworkDevices - Community Ubuntu Documentation
- WifiDocs/WirelessAccessPoint - Community Ubuntu Documentation
- Ubuntu 無線LAN設定メモ - Bird-Soft Weblog

- GW-US54GXS刺したときの状態
