WiFi boosters, also known as WiFi extenders or repeaters, receive your existing WiFi signal, amplify it, and transmit the boosted signal. This process occurs in three steps:
For example, if your router is in the living room but you struggle with connectivity in the bedroom, a WiFi booster placed halfway between the two rooms can improve the signal strength in the bedroom.
WiFi boosters come in several forms, each suited to different needs:
| Type | Description | Best For |
|---|---|---|
| WiFi Extender | Plugs into a wall outlet and connects to your router wirelessly. | Small to medium homes. |
| Powerline Adapter | Uses your home's electrical wiring to extend the network. | Homes with electrical outlets near dead zones. |
| Mesh WiFi System | A network of nodes that work together to cover a large area. | Large homes or offices. |

To determine if you need a WiFi booster, check for areas with weak signals using tools like speed tests and signal strength meters.
