How to speed up my internet connection (2026)

General guidance

Quick Answer

To speed up your internet, first work out whether the slowdown is your Wi‑Fi, your broadband line, your device, or the website or app you are using. The most effective fixes are usually restarting the router, testing with a wired connection, moving the router to a better position, reducing interference and congestion, updating router firmware and device software, and checking whether other devices are using most of the bandwidth. If a wired test is also slow and the problem persists across devices, contact your internet provider.

Overview

Slow internet is often blamed on the provider, but the real cause is just as often poor Wi‑Fi signal, interference, too many busy devices, old router settings, or a problem with one device rather than the whole connection. The quickest way to fix it is to separate the problem into parts: test the broadband coming into the property, test Wi‑Fi in the room where you use it, and test whether one device or all devices are affected. A wired test is especially useful because it removes Wi‑Fi from the equation. Once you know where the slowdown is happening, the fix becomes more obvious. If wired speeds are fine but Wi‑Fi is poor, focus on router placement, frequency band, interference, and local congestion. If everything is slow, restart the router and modem if separate, check for service outages, and contact the provider if the line remains poor. If one device is slow while others are fine, look for software updates, background downloads, malware scans, or a weak wireless adapter. You do not need specialist equipment for basic diagnosis, but you do need to test methodically rather than changing lots of things at once.

Who this is for

Home users and small households trying to improve everyday broadband and Wi‑Fi performance without changing complex network settings.

What you’ll need

  • your router and its admin details if available
  • a phone, tablet or computer
  • an Ethernet cable if you can test a wired connection
  • access to your internet provider's service status page
  • time to test when the connection is both good and bad if possible

Before you start

Check whether the problem affects one device, one room, or the whole home. If possible, pause large downloads, cloud backups, streaming, and game updates on other devices before testing, otherwise your results will be misleading.

Step-by-step

  1. 1

    Confirm what is actually slow

    Try a few different websites or apps, and check whether pages load slowly, videos buffer, downloads are slow, or only one service is affected. Then test on at least one other device if you can.

    Why: A single slow app or website does not always mean your internet is slow. Testing more than one service helps you avoid fixing the wrong problem.

  2. 2

    Restart the network properly

    Restart the router, and the modem too if it is a separate box. Let them reconnect fully before testing again. Also restart the device you are using.

    Why: This can clear temporary faults, stale connections, memory issues, and software glitches in both the network equipment and the device.

  3. 3

    Run a wired test if possible

    Connect a computer directly to the router with an Ethernet cable and test the connection again. Compare that with the speed and stability you get over Wi‑Fi in the same location.

    Why: If wired performance is good but Wi‑Fi is poor, the broadband line is probably fine and the problem is local wireless signal, interference, or router placement.

  4. 4

    Improve the router position

    Place the router in an open, central position, raised off the floor, and away from thick walls, metal objects, televisions, cordless phone bases, baby monitors, and similar electronics. Avoid hiding it in a cupboard.

    Why: Wi‑Fi weakens through obstacles and can be disrupted by interference. A better location often improves both speed and stability without spending anything.

  5. 5

    Check Wi‑Fi band and network load

    If your router offers different Wi‑Fi bands, try the one best suited to your device and distance from the router. Also check whether many devices are streaming, syncing, gaming, or downloading at the same time, and pause non‑essential activity while testing.

    Why: Different bands trade range for speed, and heavy simultaneous usage can make the connection feel slow even when the line itself is working normally.

  6. 6

    Update software and firmware

    Install operating system updates on the affected device and check the router manufacturer's or provider's instructions for firmware updates. If you changed advanced settings in the past, consider restoring sensible defaults unless your provider advises otherwise.

    Why: Updates can fix bugs, improve compatibility, patch security issues, and sometimes improve wireless performance and stability.

  7. 7

    Check for local device problems

    On the slow device, close unnecessary apps and browser tabs, disable or remove suspicious extensions, check for background downloads or cloud sync, and run a reputable malware scan if behaviour seems unusual.

    Why: A device can appear to have slow internet when the real cause is local resource use, unwanted software, or a poor wireless adapter.

  8. 8

    Check for service faults or line issues

    Look at your provider's service status page and account messages. If all devices are slow, especially on a wired connection, report the fault to the provider and tell them what you have already tested.

    Why: Once Wi‑Fi and device causes are ruled out, the remaining problem is often the broadband line, outside network, or provider equipment.

Why this works

Internet performance depends on several layers: the provider's connection to your home, the router, the Wi‑Fi environment, and the device itself. Testing each layer separately lets you identify the bottleneck instead of guessing, so you can apply the right fix and avoid unnecessary upgrades or equipment changes.

Common mistakes to avoid

  • Only testing one website or app and assuming the whole internet is slow
  • Moving the router next to interfering electronics or hiding it in a cupboard
  • Skipping a wired test and blaming the broadband when the real issue is Wi‑Fi
  • Running speed tests while other devices are streaming or downloading
  • Changing lots of settings at once so you cannot tell what helped
  • Ignoring one slow device when all other devices are working normally

Troubleshooting

Wi‑Fi is slow in one room but fine near the router

Reposition the router more centrally, reduce obstacles and interference, and consider a mesh system or additional access point if the property is large or has thick walls.

Everything is slow, including on Ethernet

Restart router and modem, check the provider's outage page, inspect cables for obvious damage or loose connections, and contact the provider if the issue continues.

Only one device is slow

Restart that device, update its software, check for background downloads or malware, forget and rejoin the Wi‑Fi network, and test it close to the router.

Internet is fast at some times and slow later

Look for peak-time congestion in your home first, such as streaming or backups, then ask the provider whether there are local capacity issues if it also happens on a wired connection.

Video calls keep freezing but browsing seems acceptable

Move closer to the router, reduce other uploads such as cloud backups, use Ethernet if possible, and restart the video app and router.

The router disconnects or needs frequent rebooting

Check ventilation and placement, update firmware if supported, inspect cables and power connections, and ask the provider about replacement equipment if the fault continues.

Compare your options

Reposition the router

Best for: Weak signal, dead spots, patchy speeds around the home

Pros: Usually free, quick, and often effective

Cons: Will not fix a poor broadband line or provider outage

Use Ethernet for key devices

Best for: Gaming, video calls, work computers, smart TVs

Pros: More stable, lower interference, easier diagnosis

Cons: Less convenient and may require cabling through the home

Upgrade to mesh Wi‑Fi or extra access points

Best for: Large homes or properties with thick walls

Pros: Better coverage across more rooms

Cons: Costs more and setup quality matters

Upgrade broadband package or provider

Best for: Homes that are consistently limited by the incoming line rather than Wi‑Fi

Pros: Can improve whole-home capacity

Cons: Won't help much if the real issue is poor Wi‑Fi or one faulty device

Alternatives

  • Use a mobile data connection or mobile hotspot temporarily if your fixed broadband is down
  • Use powerline networking or Ethernet where Wi‑Fi coverage is unreliable, though results vary by wiring and layout
  • Schedule large downloads, backups, and updates for quieter times

Pro tips

  • Test in the same place before and after each change so results are comparable
  • Keep a note of which devices are active when the internet feels slow
  • If your router combines networks automatically, try standing closer to it before assuming the broadband is poor
  • For important calls or work, a wired connection is usually the most reliable option
  • If you live in a block of flats or a dense area, interference from neighbouring Wi‑Fi may be a factor

Safety notes

  • Do not open the router or provider equipment casing unless the manufacturer says it is user-serviceable
  • Keep routers ventilated and away from heat sources to avoid overheating
  • When moving equipment, unplug power carefully and avoid straining cables or sockets

What this guide does not cover: This guide covers practical home troubleshooting for slow internet and Wi‑Fi. It does not provide advanced enterprise network tuning, provider-specific router menus, or exact speed expectations for a particular package or property.

Cost considerations

Most first-line fixes cost nothing. Costs usually arise only if you choose to replace an old router, add mesh Wi‑Fi, install cabling, or move to a faster broadband service. Before spending money, confirm whether the bottleneck is the broadband line, the Wi‑Fi environment, or one device.

Frequently asked questions

Does restarting the router really help?+

Yes, sometimes. It can clear temporary faults and reconnect the device cleanly to your provider, but if the slowdown keeps returning there is probably an underlying Wi‑Fi, hardware, or line issue.

Why is my internet fast on one device and slow on another?+

That usually points to the slow device rather than the broadband line. Common causes include outdated software, weak Wi‑Fi hardware, background downloads, browser extensions, or malware.

Should I buy a Wi‑Fi extender?+

Only if you have confirmed the problem is poor wireless coverage rather than a slow broadband line. In many homes, better router placement helps first; in larger or awkward layouts, a mesh system or properly placed access point is often a better long-term solution.

Can too many devices slow down my internet?+

Yes. Even if idle devices are not using much, several devices streaming, backing up files, downloading updates, or gaming at once can consume bandwidth and make the connection feel slower for everyone.

When should I contact my provider?+

Contact them if multiple devices are slow, a wired test is also poor, the router frequently drops the connection, or there is visible line trouble or a known service issue that does not clear.

The basic troubleshooting method changes slowly, but router features, provider tools, and network hardware options change over time.
