一、需求
1、人在公司坐昨晚写的文档放在家中电脑忘记Copy了想要访问家中电脑拿到文档。
2、家中或公司中局域网内有某台电脑或服务器要开机或者批量一键打开局域网内某些电脑
二、必备条件
1、网线连接电脑网口wifi无线网卡无法网络唤醒
2、网卡支持网络唤醒功能
三、设置
1、主板BIOS设置
目前测试过的主板微星PRO Z690-A WIFI DDR4(MS-7D25)、技嘉B75M-D3V、技嘉B85M-D2V
下面以微星PRO Z690-A为例。
主板微星PRO Z690-A WIFI DDR4
系统Windows10
路由器中兴AX5400TPLink5600和7660
发包程序C#下面有源码或者伸手党可以直接从下载链接获取发布好的应用程序
开机狂按Del键进入微星BIOS其他品牌DEL, ESC, F1, F2, F8, F9, F10, F12
- 高级–整合周边设备–网卡ROM启动设置为允许
- 高级–电源管理设置–Eup 2013设置为禁止
- 高级–唤醒事件设置–PCIE设备唤醒设置为允许
2、网卡Windows设置
- 控制面板–所有控制面板项–网络连接
- 在网卡适配器点击鼠标右键–属性弹出的属性对话框中
- 选择网络选项卡–配置
- 选择高级选项卡将
关机 网络唤醒设置为开启将魔术封包唤醒设置为开启 - 电源管理选项卡勾选下面三个选项允许此设备唤醒计算机。
- 切换为电源管理选项勾选允许此设备唤醒计算机。
- 关闭快速启动右击开始按钮点击“电源选项”点击“选择电源按钮的功能”;点击“更改当前不可用的设置”把“启用快速启动”勾选。这条必须做
3、后记
- 电脑网线连接网口处电脑关机状态下有的会有黄灯常量有的电脑不亮都能唤醒
- 在设置网卡的时候发现没有
关机 网络唤醒的选项的时候有可能是网卡驱动或者网卡版本不同没有此选项也能唤醒。

四、 外网远程唤醒方案
- 家中放一台微型迷你低功耗计算机或者网关树莓派、网关、迷你服务器功耗在10W左右保持24小时常开一年电费在一百左右。安装向日葵或者ToDesk设置无人值守支持电脑和手机App连接。随时随地连接到桌面后用远程发包软件文中源码或直接下载打包程序来远程网络唤醒局域网内其他电脑。
- 使用向日葵开机棒参照官方设置即可主要是开机棒开放了mac地址开机。可以使得开机棒不局限于一台计算机开机了。在向日葵的网站上找到开机棒或者在手机就app中找到然后输入mac地址即可。
- 使用路由器例如TP-Link自带的域名解析功能参考文章【超详细】Windows设置远程唤醒WOL+远程连接远程开机_wyouzhi@yyds的博客-CSDN博客_远程开机与远程唤醒bios设置
