How to fix Wi-Fi dead zones without guessing
Find the cause and shape of a Wi-Fi dead zone, try the free fixes, then compare the relevant networking options.
Start with the shape of the decision
A dead zone is a local radio problem, not proof that the broadband package is too slow. Mapping where it begins helps distinguish an obstruction, interference, distance or a single device issue.
Free checks first
- Test more than one device in the same place.
- Move the router into the open and change band before changing hardware.
- Compare the problem room with the hallway or doorway immediately outside it.
