WiFiを遮断する†

先日購入した中古のThinkPadX61、Bios画面でWiFiをoffにしても認識されてしまう。
WiFiは邪魔なので次のように対策。（Biosの更新をすれば良さそうなのだが面倒なので）

/etc/udev/rules.d/70-persistent-net.rulesを見ると、

# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.

# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.

# PCI device 0x8086:0x1049 (e1000e)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:16:d3:c6:41:9c", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x168c:0x1014 (ath5k)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:4c:03:1a:18", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0"

WiFiはwlan0、ドライバはath5kで自動認識されている。

/etc/modprobe.d/blacklist.confを開いて末尾に、

blacklist ath5k

と追記。

/etc/udev/rules.d/70-persistent-net.rulesを

# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#

# line, and change only the value of the NAME= key.

としてrebootする。

reboot後の/etc/udev/rules.d/70-persistent-net.rulesを見ると、

となり、WiFiは認識されなくなった。
