Microwave ovens operate on the same frequency range (2.4 GHz) as many wireless networks, which can cause significant interference in network performance especially when the oven is in use. Other electrical devices and physical barriers generally cause different types of issues such as signal attenuation or physical obstructions, but not interference of the RF signals. Poor signal strength is more of a symptom of interference rather than a cause.
