如何编写一个脚本，如果它很弱，它将重新启动我的互联网连接？

Question

我住在宾馆，房东好心让我使用他的 WiFi，但是，我的连接强度不断地从好（5 格）切换到坏（2 格）。此外，似乎我的浏览器在达到 2 小节时就会冻结，这真的很奇怪（或者可能是更奇怪的巧合），解冻它的唯一方法是断开笔记本电脑上的连接并重新连接。

我知道这可能不是最好的或永久的解决方法，但出于好奇，有没有办法编写一个脚本来在我的 WiFi 连接变弱时自动关闭和打开我的连接？如果是这样，我该怎么做？

如果重要的话，我的操作系统是 Windows 8.1。

我在网上找到了一个不错的batch script to automatically repair LAN connection，分享给大家，希望对你有帮助！
