How to Fix Common Wi-Fi Problems at Home

Start with the simple resets

Unplug your router for 30 seconds, then plug it back in and wait two full minutes. Restarting clears memory faults and forces devices to reconnect cleanly — it genuinely solves a large share of home Wi-Fi problems.

• Restart the router, not just your device
• Wait for all lights to settle before testing
• Test speed standing next to the router first

Move the router to a better spot

Routers work best high, central and out in the open. Corners, floors, metal cabinets and fish tanks all weaken the signal.

• Place it centrally, at shelf height
• Keep it away from thick walls and microwaves
• If one room is always dead, that is a placement problem, not a speed problem

Pick the right band and channel

The 2.4 GHz band travels further; 5 GHz is faster at short range. In crowded apartment buildings, switching the channel in your router settings can remove interference from neighbours' networks.

• Use 5 GHz near the router, 2.4 GHz far away
• Try channels 1, 6 or 11 on 2.4 GHz
• Give both bands the same name so devices choose automatically

Know when it is your provider

Run a speed test with a laptop plugged directly into the router. If the wired speed is also far below your plan, the problem is the connection itself — contact your provider with the test results.

Frequently Asked Questions

How often should I restart my router?

Once every few weeks is fine, or whenever speeds drop noticeably. A scheduled weekly restart is harmless.

Will a Wi-Fi extender fix everything?

Extenders help dead zones but halve speed on cheap models. A mesh system is the better fix for larger homes.
