■Squeezeに無線LANドライバを導入する
動的IP(DHCP)と静的IP(固定IP)の設定方法。
環境は以下。
Aspire One(AOA150)にSqueezeを導入
http://d.hatena.ne.jp/labunix/20130301
■Windowsドライバの取り込み準備
ドライバの確認とndisgtkのインストール。
$ sudo lspci -v | grep Wireless
03:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)
$ sudo apt-get install -y ndisgtk
$ sudo shutdown -r now && exit
■Windowsで動作実績のあるドライバファイルをコピーする。
※32bit/64bit版があるので、要注意。
netathw.cat
netathw.inf
athw.sys
■Windowsの無線LANドライバをインストール
※上記3ファイルを同じディレクトリに保存し、以下を実行。
$ sudo ndiswrapper -i netathw.inf
$ sudo ndiswrapper -l
WARNING: All config files need .conf: /etc/modprobe.d/hostap-utils, it will be ignored in a future release.
netathw : driver installed
device (168C:001C) present (alternate driver: ath5k)
■モジュールの読み込みと関連付け
$ echo "ndiswrapper" | sudo tee -a /etc/modules
ndiswrapper
$ cat /etc/modules
vga16fb
ndiswrapper
$ sudo modprobe ndiswrapper
WARNING: All config files need .conf: /etc/modprobe.d/hostap-utils, it will be ignored in a future release.
$ sudo ndiswrapper -m

adding "alias wlan0 ndiswrapper" to /etc/modprobe.d/ndiswrapper.conf ...
$ sudo depmod -a
■WARNING対応
$ cd /etc/modprobe.d/
$ sudo mv hostap-utils hostap-utils.conf
$ sudo ndiswrapper -l

■ESSIDをスキャン
$ sudo iwlist wlan0 scan | grep ESSID
ESSID:"SWS1day"
ESSID:"0001softbank"
ESSID:"MYHOME"
■手動で設定してみる。
$ sudo iwconfig wlan0 essid "MYHOME" key "s:MYHOMEPASS"
$ sudo iwconfig wlan0
