如何解决 MiFi 路由器 WiFi 频繁断线的问题?

如何解决 MiFi 路由器 WiFi 频繁断线的问题?

在此处输入图片描述

我最近从华为 E153 USB 调制解调器升级到了E583C 移动 WiFi 路由器

该设备允许我的其他设备通过 wifi 完美地访问互联网,直到我回到现在的办公室。五到三十分钟之间,我的相关计算机将失去 wifi 连接。

尝试重新连接将失败。任何尝试注册其 wifi 网络的新设备都将也失败。它需要很长时间才能“恢复”,wifi 适配器才能重新建立连接并重新获得互联网访问权限。我不得不插入 USB 电缆来维持有线网络连接。

我的同事有一个类似的 mifi 型号,华为 E5830,她遇到了完全相同的问题 - 外面很好,办公室里肯定会断线。

首先猜测是大楼里有太多其他 wifi 接入点,所以我尝试切换传输通道 1、6、11 甚至 13,但都没有更好的效果。在展开 Windows 网络诊断日志时,它显示该区域大约有 19 个网络,所以我猜干扰太大了,我的小型 mifi 设备根本无法竞争。即使我安装了延伸天线。

下面是诊断日志,我无法正确识别我可以做些什么来进一步排除故障并可能解决这个办公区域的问题?

答案1

好吧,虽然这不能解决一般问题,但具体到我的情况,我的同事告诉我大楼里有一个无线入侵防御系统 (WIPS) - 它会果酱出现在范围内的未注册的无线接入点。
