Most WiFi routers come with small, weak antennas. If you have any of these appliances at home, keep your WiFi router as far away from them as possible to boost WiFi signal. Other problematic appliances are washing machines, tumble dryers, televisions, cordless phones, and radiant heaters. The biggest emitters of electromagnetic waves tend to be found in the kitchen, and they include stoves, microwave ovens, and dishwashers. Strictly speaking, all household appliances emit electromagnetic waves to some degree, even fluorescent lightbulbs, circuit breakers, and electric razors. When in doubt, use a handheld stud finder or at least a stud finder app on your smartphone. Keep in mind that many buildings use metal studs (rather than 2x4 wood) for the particle board mounting, and placing your router close to them would be a bad idea. Other materials, including glass, wood, plastics, foam, and cardboard, can also disrupt a WiFi signal but their influence of WiFi signal strength tends to less severe. Metal is the top disrupter of a WiFi signal, and its presence close to a WiFi router can easily create a large dead zone. To start with, you want to avoid placing your router close to metal objects and appliances that emit electromagnetic waves.

Not all places are equally suitable for your router.
