Mengapa Menjalankan Microwave Saya Bunuh Konektivitas Wi-Fi Saya?

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.

After some testing with having the microwave on and off we could narrow down the problem to only occurring when the router is in

mode dan menggunakan saluran yang ditetapkan. Jika saya berubah menjadi

mode atau mengatur saluran ke

maka tidak ada masalah lagi … tapi tetap saja!

Router adalah Zyxel P-661HNU ("80211n Wireless ADSL2 + 4-port Security Gateway" dengan firmware terbaru) dan microwave dibuat oleh Neff dengan efek 1000W (jika informasi ini mungkin berguna bagi siapa saja). Ada lampu “koneksi internet” di router dan tidak padam ketika gangguan terjadi jadi saya pikir ini hanya masalah Wi-Fi internal.

Sekarang pertanyaan saya:

• Bagian apa saja dari Wi-Fi yang mungkin terpengaruh oleh penggunaan microwave? Frekuensi? Gangguan dalam sistem kelistrikan?
• Bagaimana pengaturannya

  Auto

  di

  channels

  membuat perbedaan? Saya pikir saluran yang berbeda hanya semacam sistem pemisahan dalam spektrum frekuensi yang sama?

• Mungkinkah ini pertanda bahwa microwave rusak dan perlahan-lahan memanggang kita semua di rumah? Apakah ada yang perlu dikhawatirkan?

Karena kami dapat menemukan setelan router yang bekerja sama dengan baik dengan permintaan microwave untuk perhatian, pertanyaan ini terutama karena ingin tahu. Tetapi karena kebanyakan orang di luar sana … Saya hanya tidak dapat membantu fakta bahwa saya perlu tahu bagaimana mungkin:-)

Biasanya router Wi-Fi menyebabkan masalah untuk elektronik lainnya (misalnya Wi-Fi mengganggu monitor bayi) dan tidak, biasanya, sebaliknya. Apa yang terjadi di sini?

Jawabannya

Kontributor SuperUser, Bob, menawarkan beberapa wawasan mengapa microwave menyebabkan masalah seperti itu:

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.

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.

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.

Addressing your [question about] different channels, microwave ovens (which should label the output frequency somewhere) should use ~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.

[*] 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. 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.
