A common cause of reduced Wi-Fi performance is dense walls and furniture in between routers and wireless devices. In addition to dense walls and objects, conductive materials can block Wi-Fi signals the most, causing Wi-Fi not to work in some buildings.
Everyday Materials that Block WiFi Signal
Yes, Wi-Fi technology allows your home internet connection to pass through walls, but you still need to take steps to optimize your Wi-Fi connectivity. The thickness of a wall can interfere with your internet signal, leaving you with dead zones in your home.
Move your router
For example, it is usually more difficult to get wifi throughout a house with brick internal walls than one with hollow walls. Water, metal and glass also block the signal, so it's better to place your router away from objects like radiators and fish tanks.
While there is no golden rule for fixing wireless network issues, the following tips and tricks may help improve the performance of your network.
Metal: Metal reflects Wi‑Fi signals like a mirror. Whether it's a filing cabinet, fridge, radiator, or even foil-backed plasterboard, metal disrupts your connection by deflecting signals or absorbing them entirely.
Don't keep router behind closed doors or walls
Many may be tempted to place their router behind walls or closed doors during renovations to keep it out of sight. However, that can negatively affect your WiFi signal as walls and doors can weaken or block the signal.

If your neighbors have a Wi-Fi router on the same channel within range of your router or Wi-Fi gateway, it can cause interference.
Most neighbors do not jam WiFi on purpose. Sometimes, their devices or routers cause interference. Placing your router away from shared walls can help reduce problems.
Wi-Fi can be vulnerable to obstacles and interferences including walls and floors, but you can get strong Wi-Fi that isn't affected by walls and floors. With the right devices and Wi-Fi boosters, you can get Wi-Fi in any room on any floor in your home.
WiFi interference is when other wireless signals and devices disrupt or interrupt your WiFi signal. This can happen for various reasons, such as other nearby WiFi networks, microwave ovens, PIRs and Bluetooth devices.
Signs Someone Is Using a WiFi Jammer
Bad signal quality and disconnections: Your Wi-Fi signal strength may significantly drop or disappear altogether, even when you are near your router.
In summary, the performance impact depends on the material of the fan blades, the area spanned by the fan blades, the speed of the fan and the proximity of Wi-Fi device to the fan.
Here are some of the most likely Wifi disruptors to be aware of and mitigate if possible:
The hidden network meaning is simply that the network's name isn't broadcast openly. It doesn't make your data any safer. No one encrypts or protects your info, and anyone with a simple scanner can still find the network.
Use Radio Frequency Detector
If you're looking for a more serious tool than just your phone and a flashlight, an RF (radio frequency) detector is worth having. These small handheld devices are designed to pick up wireless signals that hidden cameras (and other surveillance gear) often emit.
It reflects electromagnetic waves, preventing them from passing through. That's why elevators, metal doors, and even filing cabinets can block your signal entirely. Thick walls made of concrete or brick absorb WiFi signals rather than letting them pass through. The denser the material, the more signal it absorbs.
Although they aren't a problem in the same way that walls and microwaves are, windows can hurt your signal strength. It's easier to lose the signal when your router is placed near a window, so keep this in mind when you choose where to place your router.
Human tissue absorbs and reflects electromagnetic waves, which can lead to signal fading and interference.
Walls made of concrete, brick or metal: These dense materials can block or absorb WiFi signals, making it difficult for the signal to reach different areas of your home or office.
Mirrors: Even tiny mirrors can reflect WiFi waves away from where you want them. Glass: Thick window glass or glazing with metallic coatings can block WiFi signal. Plasterboard: Dense, insulated walls, like ones with metal inside, may block signal.
