Wi-Fi signal has a hard time going through walls

The Wi-Fi signal is an electromagnetic wave, subject to interference and signal weakening along the way. Choose well your router’s position. In addition to keeping it far from other electronic devices that may interfere with your signal and placing it in a high place, you need to consider your house floor plan, since walls and doors can also make it difficult for the Wi-Fi signal to reach every room.

When you put your router in the living room, some of the rooms may have worse Internet signal. This is because the signal is weaker due to distance and obstacles in the way (such as walls, doors, and objects). One way to try to reduce this effect is to put your router in a central area in the house, to shorten the distance between the router and the rooms.

Buying a more powerful antenna for the router (or a router with a better antenna), using signal repeaters, and removing objects that are in the way can also help improve signal range.
