Why is my internet slow? 12 fixes that actually work

Buffering, laggy calls, pages that crawl — slow internet is almost always one of a handful of causes. Before you call your provider, work through this list. Most people fix it in a few minutes, and the first step tells you whether the problem is your Wi‑Fi or the line itself.

First: is it your Wi‑Fi or your line?

Run the speed test twice — once on Wi‑Fi where you normally sit, and once right next to the router (or plugged in with a cable). If the number jumps up near the router, your line is fine and it's a Wi‑Fi problem (fixes 1–7). If it's low everywhere, including wired, it's a line problem (fixes 8–12).

Wi‑Fi fixes (when close to the router is much faster)

1. Move the router

Put it central, elevated and out in the open — not in a cabinet, on the floor, or behind the TV. Every wall and floor cuts the signal, and thick concrete or metal cuts it a lot.

2. Use the right band

Modern routers broadcast 2.4 GHz (slower but longer range, better through walls) and 5 GHz (much faster but shorter range). Connect to 5 GHz when you're near the router; fall back to 2.4 GHz for far rooms.

3. Cut the interference

Microwaves, cordless phones, baby monitors and even your neighbours' Wi‑Fi all crowd the 2.4 GHz band. Keep the router away from them and, if you can, switch to a less congested channel in the router settings.

4. Restart the router

Unplug it for 30 seconds and back on. It clears memory leaks and re-picks the best Wi‑Fi channel. If yours has run for months, this alone often helps.

5. Kick off freeloaders and bandwidth hogs

A neighbour on your Wi‑Fi, or a device doing a big cloud backup or game download, can starve everything else. Change your Wi‑Fi password and pause big transfers during calls.

6. Update the firmware

Router makers ship fixes for speed and stability. Check the admin page or app for an update.

7. Extend coverage for dead zones

If one room is always weak, a mesh system or Wi‑Fi extender — or better, a wired connection to that room — will beat fighting the signal.

Line fixes (when it's slow even wired)

8. You're testing at peak hours

Shared connections legitimately slow down in the busy evening window. Test at a quiet time (early morning) to see the line's real ceiling, and compare.

9. Turn off the VPN to test

A VPN encrypts and reroutes your traffic through a distant server, which lowers speed and raises ping. Test with it off to measure your true connection.

10. Background updates and other devices

Phones, consoles and PCs quietly download updates. Pause them, then re-test.

11. Old hardware or the wrong cable

An ageing router, an old Wi‑Fi card, or a worn Ethernet cable can cap you well below your plan. For gigabit lines, use a Cat5e/Cat6 cable and a device that supports the speed.

12. It really is the line — call your provider

If your best wired result, at a quiet hour, with no VPN, still sits well below what you pay for, that's evidence to take to your ISP. Run the test three times and note the results, connection type and time of day.
