MacBook无法连接到WLAN – 怎么办?

by Johannes

如果你的MacBook的wifi不工作,这可能有各种原因。我们为您总结了最佳和最快速的解决方案,。

MacBook wifi不工作–解决方案:重新启动。

有时,只需短暂关闭MacBook上的WLAN,然后再激活它。

  • 如果WLAN仍然不工作,通常可以简单地重新启动你的MacBook,这样WLAN模块就可以再次执行其工作。
  • 因此,保存所有程序,在采取其他措施之前,总是先尝试重新启动。这样就可以避免不必要的改变。

Repair MacBook WLAN – create new IP address

没有WIFI信号或信号不好,可能是由于分配的IP地址不正确,所以你需要获得一个新地址。

  • 打开系统设置,选择 “网络 “字段。
  • 在右边,你可以选择你要更新IP地址的网络服务。点击 “详细信息”。
  • 点击 “更多细节”,在下一个窗口选择 “TCP/IP”,然后选择 “更新DHCP租约”。
  • 用 “OK “确认,你将收到一个新的IP地址。

WLAN不工作-其他可能的原因

这可能根本不是你的MacBook在连接WLAN。要找到并修复其他可能的错误来源,请按以下步骤操作。

  • 如果你也不能与其他设备获得WLAN连接,请重新启动你的路由器。如果路由器缺少更新,你可能需要更新软件。
  • 有时苹果无线直接链接(AWDL)会导致网络连接问题。要关闭这项技术,在你的MacBook上启动终端,并输入 “sudo ifconfig awdl0 down”(不带引号)命令
  • 注意:如果你关闭苹果无线直接链接,AirDrop将不再工作。要重新打开服务,在终端输入命令 “sudo ifconfig awdl0 up”
  • 注意:如果你关闭苹果无线直接链接,AirDrop将停止工作。
