Wi-Fi Signal Optimization - Routers and location. Wireless routers are becoming more efficient but can still cause problems with some routers budget or if a large housing. Note that distance is not the main cause of the reduction in signal strength but walls Concrete and their thickness.
Wireless signal is radio time which makes it sensitive to interference. Almost any electrical appliances may interfere with the wireless signal, even simple electrical cables that emit electromagnetic field that shields. Metal objects flat screens often 100% of the signal, so if a large metal object eg washing machine that is between you and router. This will create a blind spot where the signal will be very weak or nonexistent.
