If it happens only on **2.4GHz**, wireless interference may be the cause. If your device supports it, check the 5GHz connection too. If a wired connection also drops, check both your internet connection and router.\n\nThe explanations of the frequency bands are based on sources including an Apple support article published on May 7, 2025.\n\n## In what order should you check a dropped connection?\n\nHave the affected device and your router settings information ready. You can check the connected frequency band in the router’s admin interface. If possible, also have a computer that can connect by cable ready. There are no application eligibility requirements or deadlines for these checks.\n\n1. Check the frequency band in use. Use the connected-device information in the router’s admin interface. On Windows, you can also check the properties of the connected Wi-Fi network. Do not assume the band from the network name alone.\n2. Keep the same device in the same spot and compare the connection before and during operation. Record its status while heating food as you normally would. Do not run the microwave empty for this comparison. Pause large downloads on other devices during the test.\n3. If supported, connect to 5GHz from the same spot. Both the router and device must support that band. After switching, check the actual connected band again.\n4. Check whether other devices have the same problem. If possible, connect a computer to a LAN port on the main router. Turn off the computer’s Wi-Fi during the wired test.\n5. Based on the results, change the location or channel one at a time. After each change, compare again under the same conditions. Changing several settings at once makes it harder to identify the cause.\n\nDo not judge the connection by video playback alone. A video downloaded in advance may keep playing briefly after the connection drops. Check whether a new webpage opens too. A single speed test is not enough to confirm interference.\n\n## Why does a microwave interfere with Wi-Fi?\n\nThe frequency ranges of microwaves used for cooking and 2.4GHz wireless signals overlap. Cisco describes cooking appliances as a source of non-Wi-Fi interference in that band. This means radio waves that are not Wi-Fi transmissions can also disrupt wireless reception.\n\nFood heats because it absorbs microwave energy. Water and other components in the food absorb this energy, producing heat. The same principle is used for defrosting and reheating. Heating does not always occur evenly throughout the food.\n\nWhen interference occurs, data may not be transmitted properly. Speeds may then drop, or the connection may fail to stay up. The symptoms depend on device placement and the surrounding wireless environment. The fact that a problem coincides with microwave operation does not, by itself, confirm the cause.\n\nApple’s “Resolve Wi-Fi and Bluetooth issues caused by wireless interference” gives this advice:\n\n\u003e Move your Wi-Fi device closer to your Wi-Fi router.\n\nYou can find the original on the Apple support site under that document title.\n\n## How to interpret results before and during operation\n\nA problem that occurs repeatedly only on 2.4GHz is a clue that wireless interference may be involved. The table below combines official troubleshooting principles into guidelines for interpreting results. Use each result to narrow down what to check next. It is not a definitive guide to diagnosing equipment faults or internet connection outages.\n\n| Observed result | Possible interpretation | What to check next |\n| --- | --- | --- |\n| Only 2.4GHz is unstable during operation and recovers afterward | Possible interference in that band | Check whether it happens again under the same conditions |\n| 5GHz is stable in the same spot | Switching bands may help | Check the connection in the room where you normally use the device too |\n| The connection is unstable only in a distant room, regardless of whether the microwave is running | The signal may be weakened by distance and walls | Compare the connection closer to the router |\n| Other devices work normally, but one device is unstable | Possible issue with that device’s settings or wireless adapter | Check the manufacturer’s driver and settings |\n| Wi-Fi is unstable, but a wired connection to the main router works normally | Possible problem with the wireless connection | Check interference sources and the router’s wireless settings |\n| Internet access fails on both wired and wireless connections | Possible problem with the router or a connection beyond it | Check the modem’s status and your internet provider’s outage notices |\n\nFor example, suppose only a laptop in the kitchen loses its connection while you are cooking. If 5GHz is stable in the same spot, you can consider switching bands. Do not conclude from this alone that the existing router is faulty. Check whether the same difference occurs the next time you cook.\n\n## Comparing 2.4GHz and 5GHz connections\n\n5GHz can be an option for avoiding 2.4GHz interference. However, its signal must be strong enough where you actually use the device. Intel explains that 2.4GHz generally has a wider range. Compare the effects of walls and distance too.\n\n| Comparison point | 2.4GHz | 5GHz |\n| --- | --- | --- |\n| Interference from the cooking appliance in the band | May be affected | An alternative that avoids this interference |\n| Range | Generally wider | Needs to be checked at longer distances and around obstacles |\n| Connection requirements | A device that supports the band | Both the router and device must support it |\n| Checking suitability | Compare stability before and during cooking | Compare in the same spot and where you actually use the device |\n| Problems it does not solve | Internet connection outages, device errors, and similar problems | Internet connection outages, device errors, and similar problems |\n\nReplacing the router alone does not mean every device will use 5GHz. Check the device’s specifications for its supported bands. Some models of smart appliances and other devices support only 2.4GHz. For these devices, check their location and nearby interference sources first.\n\nThe connected band may differ even when the network name is the same. Some routers select a band automatically. When comparing connections, check the actual band in the admin interface or device information.\n\n## If you use an extender, which connections should you check?\n\nIf you use an extender, check the connection between the main router and the extender too. A device may connect to the extender but still fail to access the internet. That is because the extender must also maintain its connection to the main router.\n\nTP-Link advises checking the extender’s distance and nearby interference sources. Cooking appliances and metal objects are among the things to check. The device’s connection indicator alone therefore cannot tell you whether the entire path is working.\n\n1. In the router’s admin interface, check which device the client is connected to.\n2. In the extender’s admin interface, check its connection to the main router.\n3. Move the client closer to the main router and try connecting directly.\n4. If the problem occurs only through the extender, adjust the extender’s location first.\n\n## How do you distinguish a wireless problem from an internet connection problem?\n\nConnecting to a router and accessing the internet are separate things. The Wi-Fi indicator shows the connection between the device and router. A problem can also occur farther along the path, at the modem or internet provider.\n\nOn a computer, you can use a ping test to check whether the router responds. Ping is a command that checks whether another device responds. Microsoft’s Windows connection troubleshooting documentation also recommends this method.\n\n1. Enter `ipconfig` in the Windows Command Prompt.\n2. Find the default gateway address for the Wi-Fi connection you are using.\n3. Run `ping` followed by a space and the address you found.\n4. Compare the responses before and during cooking.\n\nA response from the router does not mean every internet service is working. If there is no response, also consider whether the router is set to block responses. Compare these results with those from other devices and a wired connection.\n\nIf wired internet access also fails on multiple devices, ask your internet provider to check the connection. If only a particular website will not open, check whether that service has a problem. If the router’s indicator lights suggest it is restarting, record that too. Your model’s manual explains what the lights mean.\n\n## Common mistakes before changing settings or replacing equipment\n\nYou do not need to reset settings or buy a new product before narrowing down the cause. Intel also lists drivers and router settings as possible causes of connection problems. Check for causes that produce symptoms similar to interference.\n\n| Common assumption | What to check |\n| --- | --- |\n| A drop during cooking means the cooking appliance is faulty | Compare repeatedly before and during operation, and across bands |\n| 5GHz will be stable everywhere | Distance and walls in the room where you actually use it |\n| Switching to a particular channel will always fix the problem | Nearby networks and results before and after the change |\n| Installing an extender will also solve interference | The connection between the extender and main router |\n| Brand or the presence of a turntable determines the level of interference | The model’s specifications and its actual placement |\n\nFocus location adjustments on the router and wireless device. Try bringing them closer together while avoiding the area around the cooking appliance. Metal furniture and thick walls are also worth checking. There is no fixed separation distance that applies to every home.\n\nFollow the router manufacturer’s manual when changing channels. A channel is a communications segment within a band. You can also use automatic channel selection. If a change does not help, restore the settings you recorded.\n\n## Assess connection problems and cooking safety separately\n\nA dropped Wi-Fi connection alone cannot tell you the level of electromagnetic radiation leakage or whether safety standards are met. Connection checks and product safety checks measure different things. If the door is damaged or does not close properly, stop using the microwave. Ask the manufacturer’s service center to inspect it.\n\nThe FDA explains that microwave cooking does not cause greater nutrient loss than conventional cooking. It also does not turn cooked food into radioactive material. However, hot food and containers can cause burns.\n\n- Check that containers are marked as microwave-safe.\n- Follow the product manual’s instructions for cooking and defrosting.\n- Do not heat water longer than the time recommended in the manual.\n- Stop using the microwave if it runs with the door open.\n\nWater can become superheated without appearing to boil. Moving the cup may then cause hot water to surge up suddenly. Do not repeatedly heat water for long periods to check for interference.","content_html":"\u003cp\u003eIf your connection drops while the microwave is running, compare it before and during operation from the same spot.

Cisco and Intel describe cooking appliances as sources of interference in the 2.4GHz band. Compare the connection in the same location before and after operating the appliance to see whether the problem recurs."},{"question":"Will switching to 5GHz solve the problem?","answer":"It may help avoid 2.4GHz interference. Both the router and your device must support 5GHz. Check the signal where you use the device, too."},{"question":"Where can I check which frequency band I'm connected to?","answer":"Check the connected device information on the router's admin page. In Windows, the properties of the connected Wi-Fi network show the band. The menu for checking it varies by device and operating system."},{"question":"How should I check a device that only supports 2.4GHz?","answer":"Try adjusting the positions of the router and the device. Move them closer together while avoiding placement near the cooking appliance. You can also compare the connection before and after changing the channel, following the router's manual."},{"question":"How far should I move the router?","answer":"It's hard to specify a fixed distance that works in every setting. The results vary depending on walls, metal objects, and the device's position. Each time you move it, compare the connection under the same conditions."},{"question":"If wired internet disconnects too, is interference the cause?","answer":"Wireless interference alone is unlikely to explain it. If a wired connection through the main router's LAN port also has problems, check the router and modem. If the problem recurs on multiple devices, ask your internet service provider to investigate."},{"question":"Can the internet disconnect when I'm connected to an extender?","answer":"Yes. Even if your device is connected to the extender, there may be a problem between the extender and the main router. Compare the results with those from connecting directly to the main router."},{"question":"Should I replace the cooking appliance if the connection drops?","answer":"Connection problems alone are not enough to determine whether it needs replacing. First, check the connection band and placement. If the door is damaged or does not close properly, stop using the appliance and contact the manufacturer."},{"question":"Does a turntable-free model avoid wireless interference?","answer":"The presence or absence of a turntable alone is not enough to determine whether wireless interference occurs. Compare the connection before and after operating that model with it and the router in their current positions."},{"question":"Can a single speed test confirm interference?","answer":"A single test cannot establish the cause. Traffic from other devices and the status of the service also affect the results. Under the same conditions, check whether the difference before and after operating the appliance recurs."}],"sources":[{"url":"https://support.apple.com/ko-kr/102319","title":"Apple Support, Resolve Wi-Fi and Bluetooth issues caused by wireless interference","type":"source"},{"url":"https://www.intel.com/content/www/us/en/support/articles/000005493/wireless.html","title":"Intel, Quick Checks to Improve or Fix Wi-Fi Connection Issues","type":"source"},{"url":"https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/technical-reference/wireless-rf-reference-guide.html","title":"Cisco, Wireless RF Reference Guide","type":"source"},{"url":"https://www.intel.com/content/www/us/en/products/docs/wireless/2-4-vs-5ghz.html","title":"Intel, 2.4 GHz vs. 5 GHz vs. 6 GHz: What's the Difference?","type":"source"},{"url":"https://support.microsoft.com/en-gb/windows/experience/connectivity-networking/fix-wi-fi-connection-issues-in-windows","title":"Microsoft Support, Fix Wi-Fi connection issues in Windows","type":"source"},{"url":"https://support.microsoft.com/en-us/windows/experience/connectivity-networking/faster-and-more-secure-wi-fi-in-windows","title":"Microsoft Support, Faster and more secure Wi-Fi in Windows","type":"source"},{"url":"https://www.tp-link.com/us/support/faq/3585/","title":"TP-Link, TP-Link Range Extender Not Working?
