Certain construction materials can cause interference by absorbing or reflecting the radio waves that make up a wireless signal. For example, metals, concrete and ceramics are all known to degrade waves that pass through them, and should be kept out of Wi-Fi signal paths.

Can construction interfere with Wi-Fi?

Everything from building materials like steel and concrete to aquariums and electronics can block and disrupt Wi-Fi signals.

Can construction slow down internet?

Because the 2.4GHz signal has better penetration: it can go through walls and other solid objects more easily and travels further. A thick concrete floor or wall will stop the 5Ghz network entirely.
