How to Improve Your Home Wi-Fi Speed and Coverage

10-minute Wi-Fi tune-up
- 1
Test next to the router
Run a speed test (fast.com or your provider's app) within a few feet of the router and note the result.
- 2
Test in the slow room
Repeat in the problem room. Similar result means a plan/provider issue; much slower means coverage.
- 3
Restart modem, then router
Unplug both, power the modem first, wait until its lights settle, then the router.
- 4
Move the router
Central, raised, out of cabinets, away from microwaves and fish tanks.
- 5
Update firmware
Open the router app or admin page and install any update.
- 6
Wire the big devices
Plug TVs, consoles and desk PCs near the router in with Ethernet.

Re-test and decide
Still dead zones after all this? It's time for mesh. See our router guide.
First, find out what kind of slow it is
Run a speed test standing next to the router, then in the room where it's slow. Same slow speed in both? The problem is your internet plan or provider. Fast near the router but slow far away? That's a Wi-Fi coverage problem, and the fixes below help.
Free fixes, in order
1. Move the router. Put it in the middle of the home, up high, out of cabinets, and away from microwaves, fish tanks and thick walls.
2. Restart it. Unplug for 30 seconds. It clears memory problems that build up over weeks.
3. Update firmware. Open the router app or admin page and install updates. They fix bugs and security holes.
4. Use 5 GHz (or 6 GHz) up close. These bands are faster but shorter-range. 2.4 GHz reaches farther but is slower and more crowded.
5. Kick off old devices. Forgotten tablets and smart gadgets still use airtime. Remove what you don't use.
6. Use Ethernet for the big stuff. A TV, console or desk computer near the router should be wired. It frees up Wi-Fi for everything else.
When to spend money
If your router is more than about five years old, it may not support newer Wi-Fi standards. Upgrading can help a lot.
If you have dead zones in a larger or multi-floor home, a mesh system usually beats a single extender. See our mesh vs single router guide to decide.

Common questions
Do Wi-Fi extenders work?
They can help one dead spot, but they often halve speed and create a separate network name. Mesh systems handle whole-home coverage more smoothly.
How often should I restart my router?
Only when things feel slow, or after updates. Some routers let you schedule a weekly restart automatically.
