Most "slow internet" complaints turn out to be a Wi-Fi coverage problem, not a plan problem. Here's where to start.

1. Move the modem to a central, elevated spot

Wi-Fi signal degrades through walls and floors. A modem tucked in a cupboard or corner will always underperform compared to one in an open, central location.

2. Check for interference

Microwaves, baby monitors and older cordless phones can all interfere with the 2.4GHz band. If your devices support it, switch to 5GHz for less congestion.

3. Restart it occasionally

Modems and routers benefit from an occasional restart, clearing memory and reconnecting to the best available channel.

4. Update your modem's firmware

Manufacturers regularly patch performance and security issues. Check your modem's admin page for available updates.

5. Add a mesh point for larger homes

If you've got dead zones in back bedrooms or garages, a single router often isn't enough — a mesh system extends coverage without the drop-off you get from traditional Wi-Fi extenders.

6. Confirm it's actually a Wi-Fi issue

Run a speed test with a laptop plugged directly into the modem via ethernet. If that's fast but Wi-Fi is slow, the problem is coverage, not your plan.
