Slow internet is one of the most frustrating things about modern life. You're trying to watch something, join a video call, or just browse the web — and everything grinds to a halt. But before you ring your provider and spend an hour on hold, there are a few things worth checking yourself.
Here's a plain English breakdown of the most common causes of slow internet — and what to do about each one.
1. Your Router Needs a Restart
This sounds too simple, but it works more often than you'd think. Routers can get bogged down over time, just like computers. Unplugging yours for 30 seconds and plugging it back in can clear a surprising number of issues.
What to do: Unplug your router from the wall, wait 30 seconds, plug it back in, and wait 2 minutes for it to fully reconnect.
2. Too Many Devices Are Connected
Every device connected to your Wi-Fi is sharing the same bandwidth. If you've got phones, tablets, smart TVs, games consoles and laptops all connected at once, your speed is being split between all of them.
What to do: Disconnect any devices you're not actively using. Check your router's app or settings page to see what's connected.
3. You're Too Far From the Router
Wi-Fi signal weakens with distance, and walls — especially thick stone or brick ones — make it worse. If you're using your device in a room far from the router, that could be your problem.
What to do: Move closer to the router to test. If speed improves significantly, consider a Wi-Fi extender or mesh system for your home.
4. Your Wi-Fi Channel Is Congested
If you live in a flat or terrace, your router may be competing with dozens of neighbouring routers all using the same Wi-Fi channel. This causes interference and slows everything down.
What to do: Log into your router settings and try switching the Wi-Fi channel. Channels 1, 6, and 11 are usually the least congested on 2.4GHz.
5. Your Broadband Package Is Simply Too Slow
Sometimes the issue isn't a fault — it's that your broadband speed just isn't fast enough for what you're trying to do. HD video streaming requires around 5Mbps, 4K needs 25Mbps, and if multiple people are streaming at once, you need more.
What to do: Run a speed test at fast.com to see what speed you're actually getting. Compare it to what you're paying for — if there's a big gap, contact your provider.
6. The Problem Is Your Device, Not the Internet
Sometimes what feels like slow internet is actually a slow device. An old laptop or phone may struggle to keep up even on a fast connection.
What to do: Test your internet speed on another device. If the other device is faster, the issue is with your original device rather than your broadband.
Still Slow After Trying Everything?
If you've worked through all of the above and your internet is still crawling, there may be a fault on your line, a problem with your router hardware, or a configuration issue that needs a closer look.
