微波炉怎么干扰 WiFi？家用干扰源与影响

There are a variety of household devices and electronics that can interfere with your Wi-Fi signal, but most don’t have the ability to do so quite so spectacularly as a microwave oven. Read on as we explore how a microwave can wreak havoc on your wireless network.

有各种各样的家用设备和电子设备会干扰您的Wi-Fi信号，但是大多数设备都无法像微波炉那样具有如此出色的功能。 在我们探索微波如何对无线网络造成严重破坏时，请继续阅读。

问题 (The Question)

SuperUser reader Ohlin wants to know why his microwave is slaying his Wi-Fi connectivity:

超级用户读者Ohlin想知道为什么他的微波会破坏Wi-Fi连接：

Every time I start the microwave in the kitchen, our home Wi-Fi stops working and all devices lose connection with our router! The kitchen and the Wi-Fi router are in opposite ends of the apartment but devices are being used a little here and there. We’ve been annoyed by the instability of the Wi-Fi for some time and it wasn’t until recently we realized it was correlated to microwave usage.

每次我在厨房里打开微波炉时，我们的家庭Wi-Fi都会停止工作，所有设备都将与路由器失去连接！ 厨房和Wi-Fi路由器位于公寓的两端，但是到处都是使用一些设备。 Wi-Fi的不稳定一直困扰着我们，直到最近我们才意识到它与微波的使用有关。

After some testing with having the microwave on and off we could narrow down the problem to only occurring when the router is in b/g/n mode and uses a set channel. If I change to b/g mode or set channel to auto then there is no problem any more…but still!

经过一些有关打开和关闭微波的测试，我们可以将问题缩小到仅当路由器处于b/g/n模式并使用设置的信道时才发生。 如果我更改为b/g模式或将通道设置为auto ，则再也没有问题了……但是！

The router is a Zyxel P-661HNU (“802.11n Wireless ADSL2+ 4-port Security Gateway” with latest firmware) and the microwave is made by Neff with an effect of 1000W (if this information might be useful to anyone). There is an “internet connection” light on the router and it doesn’t go out when the interruption occurs so I think this is only an internal Wi-Fi issue.

该路由器是Zyxel P-661HNU (“ 802.11n无线ADSL2 + 4端口安全网关”，具有最新固件)，微波由Neff制造，功率为1000W(如果此信息可能对任何人有用)。 路由器上有一个“互联网连接”指示灯，当中断发生时它不会熄灭，所以我认为这只是内部Wi-Fi问题。

Now to my questions:

现在我的问题是：

• What parts of the Wi-Fi can possibly be affected by the microwave usage? Frequency? Disturbances in the electrical system?

  微波的使用可能会影响Wi-Fi的哪些部分？ 频率？ 电气系统故障？

• How can setting Auto on channels make a difference? I thought the different channels were just some kind of separation system within the same frequency spectrum?

  如何在channels上设置Auto会有所不同？ 我以为不同的通道只是同一频谱内的某种分离系统？

• Could this be a sign that the microwave is malfunctioning and slowly roasting us all at home? Is there any need to be worried?

  这是否表明微波炉出现故障并在家里慢慢地烧烤我们所有人？ 有什么需要担心的吗？

Since we were able to find router settings that cooperate well with our microwave’s demand for attention, this question is mainly out of curiosity. But as most people out there…I just can’t help the fact that I need to know how it’s possible 🙂

由于我们能够找到与微波需求引起关注的路由器设置，因此这个问题主要是出于好奇。 但是，就像大多数人一样……我实在不由得需要知道这是怎么可能的事实:-)

Typically it’s the Wi-Fi router causing trouble for other electronics (e.g. the Wi-Fi interferes with the baby monitor) and not, usually, the other way around. What’s going on here?

通常，这是Wi-Fi路由器给其他电子设备造成麻烦(例如，Wi-Fi干扰了婴儿监护仪)，而通常不会引起其他麻烦。 这里发生了什么？
