如何用指令停用及啟用網卡

[1]中提到數種方法，其中

netsh int set interface name="Local Area Connection 3" admin=disabled
netsh int set interface name="Local Area Connection 3" admin=enabled

看來最簡短，但實際執行失敗，會出現如[2]fcretusys所說的情形，[2]中亦提及Win2003可正常運作。

One or more essential parameters not specified

The syntax supplied for this command is not valid. Check help for the correct sy
ntax.

Usage set interface [name = ] IfName
[ [admin = ] ENABLED|DISABLED
[connect = ] CONNECTED|DISCONNECTED
[newname = ] NewName ]

Sets interface parameters.

IfName - the name of the interface
admin - whether the interface should be enabled (non-LAN only).
connect - whether to connect the interface (non-LAN only).
newname - new name for the interface (LAN only).

Notes:
- At least one option other than the name must be specified.
- If connect = CONNECTED is specified, then the interface
is automatically enabled even if the admin = DISABLED
option is specified.

[1][3][4]中提到用devcon工具[5]，為一指令式的裝置管理員

使用下列指令可得到網卡資料，需注意事項" hwids 空格 =net"

devcon hwids =net

輸出結果如：

選擇網卡資料之Compatible ID's:的第一筆資料，如下指令可成功停用及啟用網卡。

停用：

devcon disable "PCI\VEN_10EC&DEV_8167&REV_10"

啟用：

devcon enable "PCI\VEN_10EC&DEV_8167&REV_10"
