Can WiFi Go Through Walls?

In theory, Wi-Fi signals are capable of passing through walls and other obstacles relatively easily.

However, in reality, some walls are thicker or use reinforced concrete and may block some of the signals.

Materials such as drywall, plywood, other kinds of wood and glass can be easily penetrated by wireless signals.

How can I boost my WiFi signal in the wall?

Boost your home wi-fi signal

  • 1) Check the position of your router. Moving your router slightly away from its current position may help, but it’s more likely a wholesale change is in order.
  • 2) Fit a microfilter to your ADSL socket.
  • 3) Change the wireless channel or frequency band.
  • 4) Try the tin foil approach.
  • 7) Turn an old router into a repeater.

Can WiFi signal pass through metal?

Wireless Signal Interference

Wireless signals are degraded as they attempt to pass through dense materials such as concrete, bulletproof glass and metal; signals fare better when passing through wood, regular glass and even brick.

What materials can block a WiFi signal?

Some material suggestions include:

  1. Aluminum foil.
  2. Steel baking pans.
  3. Glass baking pans.
  4. Cardboard.
  5. Plastic.
  6. Large container filled with water.
  7. Human body.

Does 5GHz WiFi go through walls?

Today’s WiFi gear operates at either 2.4GHz or 5GHz. Their higher frequencies make it harder for the signals to maintain their strength as they pass through obstructions. According to the WiFi Alliance, 802.11ah will also achieve nearly double the range of current standards. There’s another bonus, too.
