Home Network Fixes, Step by Step

Network problems fall into three layers: the line coming into your home, the router, and the Wi-Fi between the router and your devices. Testing each layer in turn tells you where to focus.

Step 1: Test the line

Plug a laptop directly into the router with a network cable and run a speed test. If the wired result is far below your plan, the problem is likely the line or the provider. Restart the router and test again before calling them.

Step 2: Test the Wi-Fi

Run the same test over Wi-Fi next to the router, then in the problem room. A big drop between the two points to coverage, not the line. See why Wi-Fi is slow.

Step 3: Improve coverage

• Move the router to a central, raised, open spot.
• Keep it away from microwaves, fish tanks and thick walls.
• Add a mesh system or a wired access point for larger homes.

Step 4: Tidy the settings

• Install router firmware updates.
• Try a less crowded channel if neighbors’ networks overlap.
• Let newer devices use the faster band when available.

Step 5: Secure it

Change default passwords, use modern encryption and remove devices you do not recognize. Walkthrough in securing your router.

When it is not you

If wired speeds stay low after restarts, or the connection drops at the same times daily, record your test results and contact your provider. Evidence speeds up the conversation.
