Is your Wi-Fi acting up lately? Maybe your devices are connecting just fine in the living room but drop the signal in that cozy upstairs office or back bedroom. Before you invest in expensive boosters or call your internet provider, here’s a surprising DIY trick that could actually help: aluminium foil. Yes, it sounds strange—but this simple kitchen staple might be the solution to your home’s Wi-Fi dead zones.
