How to Fix Slow Internet: 12 Practical Steps
8 min read
Slow internet is one of the most frustrating everyday problems — and most of the time you can fix it yourself in a few minutes, without calling your provider. This guide walks through the fixes in order, starting with the quickest wins. Work down the list and run a speed test after each change so you can see what actually made a difference.
Start here: measure before you fix
Before changing anything, run a speed test and write down your download, upload, and ping. Compare the result to the plan you pay for. If you pay for 100 Mbps and get 90, that is normal. If you get 12, something is wrong. Having a baseline tells you whether your fixes are working.
1. Restart your router and modem
It sounds like a cliché, but power-cycling genuinely fixes a large share of slowdowns. Routers run for months without a reboot and slowly accumulate memory leaks, overheating, and congested connection tables. Unplug both the modem and router, wait 30 seconds, plug the modem back first, wait for it to come online, then the router. Give it two minutes and test again.
2. Test with a cable to rule out Wi-Fi
Plug a laptop directly into the router with an Ethernet cable and test. If the wired speed is good but Wi-Fi is slow, your problem is the Wi-Fi — not your internet plan. That narrows things down enormously and points you to steps 4–7.
3. Check who (and what) else is using the connection
A single large download, a cloud backup, a game update, or someone streaming 4K can saturate your connection. Pause big downloads and updates, then retest. Smart TVs, consoles, and phones often update in the background without you noticing.
4. Move closer to the router
Wi-Fi weakens fast with distance and through walls. If you are two rooms and a concrete wall away, your speed can drop by half or more. Test in the same room as the router. If that fixes it, the issue is coverage, not speed.
5. Reposition the router
Place the router high, central, and out in the open — not inside a cabinet, behind the TV, or on the floor in a corner. Keep it away from microwaves, cordless phones, and thick metal objects, which all interfere with the signal.
6. Switch to the 5 GHz band
Modern routers broadcast two bands. The 2.4 GHz band reaches further but is slower and more crowded; the 5 GHz band is much faster over short distances. If your network shows two names (often with "5G" in one), connect to the 5 GHz one when you are near the router.
7. Change your Wi-Fi channel
In apartments, dozens of nearby networks can crowd the same channel and slow everyone down. Most routers have an "Auto" channel setting; sometimes manually choosing a less congested channel (1, 6, or 11 on 2.4 GHz) helps. You can change this in your router's admin page.
8. Update the router firmware
Manufacturers release firmware updates that fix bugs and improve performance and security. Log into your router's admin page (usually 192.168.0.1 or 192.168.1.1) and check for updates. Many newer routers do this automatically.
9. Scan for devices you don't recognise
If neighbours are on your Wi-Fi, they are eating your bandwidth. Check the connected devices list in your router settings. If you see anything unfamiliar, change your Wi-Fi password to a strong one and reconnect your own devices.
10. Clear up your device
Sometimes the "slow internet" is actually a slow device. Close unused browser tabs and apps, restart the computer or phone, and check that a background sync or antivirus scan isn't hammering the network. Test on a second device to confirm.
11. Consider your hardware's age
If your router is more than five or six years old, it may not support the speeds you now pay for. An old router can cap a gigabit plan at a fraction of its potential. Upgrading to a modern Wi-Fi 6 router — or adding a mesh system for larger homes — often delivers the biggest jump.
12. Call your provider (with evidence)
If wired speeds are still far below your plan after all of the above, the problem is on your provider's side — a line fault, congestion, or throttling. Call them with your recorded speed tests and the times you ran them. Concrete numbers get problems taken seriously far faster than "my internet is slow".
The bottom line
Most slow-internet problems come down to Wi-Fi coverage, an overloaded connection, or ageing hardware — not your actual plan. Work through this list top to bottom, retesting as you go, and you will usually find the culprit. When you are done, run a final speed test to confirm the improvement.
