Once you know your problem is coverage, not your internet plan, there are three common ways to fix it. Each has a place.
Range extender
A range extender plugs into a wall outlet partway between the router and the weak room. It listens to your router's signal and repeats it.
- Good: inexpensive and quick to set up.
- Not so good: many extenders cut the speed, because they have to receive and resend on the same radio.
- Not so good: some create a second network name, so devices stay stuck to the weaker one as you walk around.
- Best for: one small dead spot where you only need basic browsing.
Mesh Wi-Fi system
A mesh system replaces or works alongside your router with two or more units placed around the home. They talk to each other and show up as a single network name, handing your devices from one unit to the next as you move.
- Good: one network name, even coverage, usually a simple phone app to set it up.
- Good: better models use a dedicated connection between units so speed holds up.
- Not so good: costs more than an extender.
- Best for: larger homes, multi-story homes, or homes with thick walls.
A network cable
A network cable (often called an Ethernet cable) carries the connection through a wire instead of the air. You can plug a computer, TV or game console straight in, or run a cable to a second Wi-Fi access point or mesh unit in the far room.
- Good: the fastest and most reliable option; walls do not affect it.
- Not so good: running a cable through a home can take some work.
- Tip: many mesh systems can use a cable between units, which gives you the best of both.
How I would choose
- If a cable can reach the room without much trouble, start there.
- If not, and the house is large or has thick walls, go with mesh.
- If it is one small spot and a light need, an extender can be enough.
- Whatever you choose, place units within good range of each other, not in the dead spot itself.
