Household interference ~~with Wi-Fi signals~~ and router placement issues

Common household items and environmental factors can significantly degrade Wi-Fi signal quality and stability. Key sources of interference include metal surfaces, such as steel cabinets, and various electronic devices like landline phones, refrigerators, and baby monitors. Microwave ovens are a notable cause of disruption because they operate on frequencies near the 2.4 GHz Wi-Fi band. While the Federal Office for Radiation Protection (Bundesamt für Strahlenschutz) indicates that microwave leakage radiation typically remains below safety limits, it can still interfere with ~~routers~~ routers, repeaters, and other wireless devices. Beyond general electronics, the improper placement of hardware can further hinder performance. Placing routers on the floor, in enclosed spaces like TV cabinets, or behind large metal objects obstructs signal propagation. Furthermore, placing a power adapter directly behind a router can cause electromagnetic interference and heat buildup. This heat can lead to thermal throttling, causing the device to slow down or disconnect. To mitigate these issues, experts and industry associations like Bitkom recommend positioning routers in central, ~~elevated~~ elevated, and open locations away from metal objects and other electronics. It is also advised to keep power adapters separated from the router. Additionally, managing bandwidth consumption from smart home ~~devices~~ devices, such as vacuum robots, and maintaining up-to-date firmware can help improve network stability.
