How to Keep a Microwave From Interfering with WiFi

There are a few things you can try to stop a microwave from interfering with a wireless router’s signal.

Switch to 5 GHz

  1. If your microwave does include wireless features to interact with a smartphone app and the like, it is likely the oven uses the 2.4 GHz band for wireless signals.
  2. Switch to 5 GHz frequencies on your wireless router by following the instructions that originally accompanied your router.
  3. You can typically check which wireless GHz frequency you are using via your settings app on your smartphone.

Isolate Your Routers

  1. If you use multiple routers throughout your home, make sure they are isolated from one another.
  2. If multiple routers are in the same room, a microwave can easily cause interference across all wireless routers and any Wi-Fi connection or WiFi signal.
  3. Simply move any errant routers to rooms situated far away from the microwave oven.

Keep Microwave Away from Devices

  1. Another thing you should try is to separate the microwave oven from any other wireless devices, such as radio frequency transmitters and even computers.
  2. Make sure routers are close enough to a microwave to allow transmission but far enough away so as to discourage interference to a WiFi signal.

Grin and Bear It

  1. If none of these solutions work for your setup, you can always choose to simply accept the interference and move on.
  2. A microwave will likely only cause interference while it is being used.
