当电脑无法上网,显示电脑连不上wifi的时候怎么办呢?很多网友都遇到过这种问题,不知道为什么连不上wifi?导致出现这个问题的原因很多,下面小编就教下大家常见的电脑连不上wifi的原因和解决方法.
一、查看家里的路由器是否在正常运行，wifi上的执事信号灯是否是绿灯，如果有变成红灯，或者不亮的情况，那么试试重启路由器。
二、检查WiFi开关是否打开。有些笔记本电脑会有无线网络的硬件开关。如果关闭，则可以打开。当然，笔记本电脑也有控制无线网络的快捷键。我们可以检查电脑上的F功能键是否有WiFi图标或飞行模式。编辑是F5。按FN F5启动无线网络。
三、检查网卡驱动程序和WiFi服务是否有问题。
1、右键单击计算机图标并选择管理。
2、打开窗口，选择设备管理器，然后检查网络适配器是否有黄色图标。如果是，则需要重新安装网卡驱动程序。
3、如果驱动程序没有问题，请展开服务和应用程序，单击服务，找到WLAN自动配置，然后单击左上角启动服务。
四、检查网络是否被禁用
1、【win+i】打开设置，点击网络和Internet。
2、单击右侧的“更改适配器”选项。
3、在“打开”窗口中，右键单击使用的WiFi连接，然后选择“启用”即可。
以上就是详解为什么电脑连不上wifi，希望能帮助到大家。
