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.

## 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.

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？

## 答案 **(**The Answer**)** ##

SuperUser contributor Bob offers some insight into why the microwave is causing such problems:

超级用户贡献者Bob提供了一些有关微波为何导致此类问题的见解：

> 802.11 (b/g/n) typically operates on the 2.4 GHz band. This is conveniently the same/very close to the band that your microwave oven emits. It’s also an [ISM band][], which can be freely used at low power without licence – it was originally supposed to be used for non-communication purposes, but the lack of a licence requirement makes it very attractive.
> 
> 802.11(b / g / n)通常在2.4 GHz频段上运行。 这很方便，与微波炉发出的波段相同/非常接近。 它也是一个[ISM频段][ISM band] ，无需许可证即可在低功率下免费使用-最初应将其用于非通信目的，但是由于缺少许可证要求，因此非常有吸引力。
> 
> Most microwave ovens tend to be very well shielded and will not emit enough radiation\[\*\] to interfere with wireless communications. It is possible that your unit has a damaged shield. You could look into replacing it.
> 
> 大多数微波炉的屏蔽效果都很好，并且不会发出足够的辐射\[\*\]来干扰无线通信。 您的设备的屏蔽层可能已损坏。 您可以考虑更换它。
> 
> A better thing to do would be to upgrade your wireless networking equipment and devices (note that many, especially older, devices are 2.4 GHz only) to be 5 GHz compatible (used with 802.11 a/n). This is the other major band WiFi networks can operate in (though 2.4 is far more common), and should not suffer interference from microwave ovens.
> 
> 更好的做法是将无线网络设备和设备(请注意，许多设备，尤其是较旧的设备仅2.4 GHz)升级为5 GHz兼容(与802.11 a / n配合使用)。 这是可以在其他主要频段内运行的WiFi网络(尽管2.4更为常见)，并且不应受到微波炉的干扰。
> 
> Addressing your \[question about\] different channels, microwave ovens (which should label the output frequency somewhere) should use ~2.450 GHz.
> 
> 为解决有关不同频道的问题，微波炉(应在某处标记输出频率)应使用〜2.450 GHz。
> 
> WiFi (b/g/n) channels typically range from 2.412 GHz to 2.472 GHz, with a bandwidth of 20 MHz and a 2 MHz band gap. If you pick a channel from the upper or lower end, and *assuming* your microwave oven is precise enough with its frequency, you could sidestep it entirely. This is, however, just a guess.
> 
> WiFi(b / g / n)通道的范围通常为2.412 GHz至2.472 GHz，带宽为20 MHz，带隙为2 MHz。 如果从上端或下端选择一个通道，并*假设*微波炉的频率足够精确，则可以完全避开它。 但是，这只是一个猜测。

> \[\*\] I must point out that 2.4 GHz is far from ionising radiation, which is at least 2400000 GHz (the type that can harm human tissue and/or cause cancer). Even *if* the shield is faulty, it [will *not* cause any harm][will_not_cause any harm]. Any (very slight) damage would be caused by heating (and not directly by ‘radiation’), which you most definitely *will* feel before any real damage. Also, just don’t stand in front of it for hours a day. That always helps.
> 
> \[\*\]我必须指出，2.4 GHz离电离辐射很远，电离辐射至少为2400000 GHz(会伤害人体组织和/或导致癌症的类型)。 *即使*屏蔽故障，它[*不会*造成任何伤害][will_not_cause any harm] 。 任何(非常轻微的)损坏都是由加热(而不是直接由“辐射”引起)造成的，您在任何实际损坏之前肯定*会*感觉到。 此外，只是一天不要站在它前面几个小时。 这总是有帮助的。
