“无法连接到此网络”故障排除

经过大量研究和测试在 SuperUser 和网上找到的其他答案后，我无法解决：

  • 除一台电脑外，我连接到路由器的所有设备均正常连接/工作。
  • 这些设备包括 3 部 Android 手机、1 部 MacBook、1 部笔记本电脑和两部 Android 平板电脑。全部运行正常，没有任何问题。
  • 无法连接的 PC 甚至不会触碰路由器，我无法解决这个问题，这真是让我很恼火。
  • 我尝试过重置 winsock、更新驱动程序、尝试过使用 wifi 加密狗，但都没有成功。

问题

  • 因此，一切似乎都正常，但是尽管信号非常强（RSSI：255），系统似乎也看不到路由器，并拒绝继续连接。

什么有效

  • 所有其他设备都运行正常，没有理由怀疑路由器有问题。同时，笔记本电脑连接到任何其他网络也没有任何问题。

这两者之间似乎存在某种特殊的仇恨。问题与系统无关，因为我正在运行 Win 7 和 Win 10 双启动，情况完全相同。

答案1

查看您的日志，似乎您的 RSSI 为 -68（这很好）。您似乎还使用 WEP 作为安全机制。一些较新的无线驱动程序不再支持 Wi-Fi 联盟规定的 WEP。请将您的安全性更改为 WPA2-PSK，看看您的笔记本电脑是否与接入点（或用您的话来说，路由器）关联。让我知道进展如何。

答案2

您是否偶尔会出现蓝屏？我遇到了同样的问题，路由器无法连接，偶尔会出现蓝屏。有一天我的硬盘出现故障。将硬盘从系统中取出后，蓝屏问题就消失了，我的路由器连接上了，PC 启动和关闭的速度也快了很多。这只是我的想法。

您可能需要运行 HDD 诊断程序。Western Digital 提供免费的基本智能驱动器信息测试器。这是链接。您需要单击适用于 Windows 的软件，然后单击适用于 Windows 的 Data Lifeguard Diagnostic。我知道有更高级的程序可以做到这一点，但我不知道它们在哪里。希望这对您有所帮助。

答案3

经过两天的搜索和查看日志后，我放弃了，并打电话给技术支持。他只是在 Windows WiFi 设置中启用了随机硬件地址，然后就成功了![这个技巧对我有用
