Correlate the interruption with ordinary appliance use and compare a supported alternative band or position.

A kitchen connection that becomes unreliable during microwave use may be affected by local radio interference. Cisco identifies microwave ovens among sources that can interfere with 2.4 GHz Wi-Fi. The timing is a clue to test, not proof that every nearby appliance is faulty.
Record normal behavior
Use the same client in the usual kitchen position and note whether the connection works before, during and after ordinary appliance use. Do not run an appliance empty or modify it for a network experiment. Keep the test limited to normal safe operation.
Identify both wireless links
If the client uses an extender, check the band between client and extender and the band between extender and router. Moving the phone to 5 GHz may not solve the issue if the extender’s upstream connection still relies on the affected 2.4 GHz path.
Compare a supported alternative
Where both devices support it and coverage is adequate, test a 5 GHz connection. Alternatively, move the networking device to a safe position farther from the appliance and large metal surfaces. Change one factor at a time.
Check the wider network
- Does a wired device remain online?
- Does another room lose service at the same time?
- Does the extender report an upstream disconnect?
- Does the symptom stop when normal appliance use ends?
These observations help distinguish a local radio issue from a provider outage or a power interruption.
Choose a lasting placement
Keep networking hardware away from unsuitable kitchen locations, moisture and blocked ventilation. A wired access point path can reduce dependence on the affected upstream radio segment where cabling is practical.
Do not open or alter the microwave to improve Wi-Fi. If the appliance itself shows abnormal behavior, have it assessed through appropriate service. For the network, the goal is a repeatable improvement in the kitchen under normal household conditions, with the relevant wireless path identified and a safe placement retained.
