If you experience disruptions to your Wi-Fi (5GHz) signal when the microwave is turned on, it could be an indication of electromagnetic interference (EMI) caused by the microwave. Microwave ovens emit electromagnetic waves in the 2.4GHz frequency range, which can potentially interfere with Wi-Fi signals operating in the same frequency band.
Here are a few things you can try to mitigate the interference:
Reposition your devices: Try repositioning your Wi-Fi router and microwave oven. Keep them as far apart as possible, preferably in different rooms, to minimize the potential for interference.
Use the 5GHz band: Most modern routers support both the 2.4GHz and 5GHz bands. The 5GHz band is less prone to interference from household appliances like microwaves. Connect your devices to the 5GHz network if possible to reduce the impact of microwave interference.
Check your router settings: Some routers have settings that allow you to automatically select the least congested Wi-Fi channel. Ensure that your router is set to choose the best channel to avoid overlapping with the microwave frequency.
Upgrade your microwave or router: Older microwave ovens may emit stronger interference than newer models that comply with updated regulations and standards. If your microwave is particularly old and causing significant disruption, replacing it with a newer model that offers better shielding could help reduce interference. Similarly, upgrading your Wi-Fi router to a newer model with improved shielding and better performance might also help.
It's important to note that occasional interference from the microwave is relatively common, and it doesn't necessarily indicate a faulty microwave. However, if the interference is severe and persistent, it may be worth considering replacing the microwave to see if the issue improves. If you're unsure about the microwave's shielding or have concerns about its safety, it's recommended to consult a professional or contact the manufacturer for further guidance.
