如果我在楼上，Wifi 就无法连接

我发现当我在客厅时，WiFi 可以连接，因为互联网路由器等就在那里。但是如果我尝试在楼上连接，就无法连接。在 Windows 7 中启动（双启动 :D ）我发现 WiFi 可以连接。我觉得这很令人困惑，并且从安装开始就有这种情况。请帮忙！

亲切的问候。

希望能帮助到你！

大家好，我刚刚尝试在楼上连接互联网，令我惊讶的是，它确实连接上了。不知道具体原因。我最近唯一做的事情就是输入 bij Oli 的代码并安装 Jupiter 和 laptop-mode-tools。我真的不知道这是否会影响我的互联网，但这是我唯一能想到的办法。感谢大家的帮助，真的很感激 :)

PS 如果有人认为这可能对其他人有帮助，我愿意帮助找到这个问题的“真正”解决方案。只需在此处发布我需要发布的内容，我将尽力提供帮助。

grep "Sensitivity" -B2 也没有带来任何结果

发现一件奇怪的事情：它确实连接到楼上，但只连接到我门附近。我房间的其他地方都无法连接，而窗户可以连接。

答案1

通常，您可以从楼上看到更多邻居的路由器。您可能需要选择一个更不常用的频道。
