While most people set up their routers in the corner of a room (given that is how most homes are designed), it is best advised to have the router placed centrally so that it covers the entire home. However, it is also advisable to place it in a place where you use the internet the most.Moreover, it is also a good practice to avoid keeping metal objects around your router as metal dissipates electromagnetic signals. Having concrete or brick walls near your router will also be bad for the signal strength as concrete absorbs these signals. Moreover, keeping your router near a microwave is also ill-advised. You may notice that your internet will slow down every time you turn your microwave on! This is because Microwave operates at the same frequency as a WiFi router. It is best advised to set it up at a high place.
