Start with what's actually slowing you down

Before you change settings or buy new equipment, find out whether the problem is your internet connection itself or something on your computer. Open a speed test site like Speedtest.net or Fast.com on your PC and run the test. Write down the read and upload numbers. Then run the same test on your phone using the same WiFi network.

If your phone gets much faster speeds than your PC, the problem is your computer or how it connects to the network — not your internet service. If both devices get slow speeds, the problem is your internet connection or your router, and you may need to contact your internet provider or replace the router before PC-level fixes will help.

This one step saves you hours of troubleshooting. Many people spend a weekend changing PC settings when they actually need a new router or a call to their provider.

Key Takeaways

  • Run a speed test on your PC and your phone to tell whether the problem is your computer or your internet connection itself.
  • Close background programs that use the network — especially cloud storage apps like OneDrive, Dropbox, and Google Drive, which sync constantly.
  • Move closer to your router or switch from WiFi to a wired Ethernet cable, which is faster and more stable than wireless.
  • Restart your router by unplugging it for 30 seconds, which clears its memory and often restores speed without any other changes.
  • Update your WiFi drivers and your router's firmware, both of which can improve connection speed and stability.

Close programs that are using your network in the background

Cloud storage apps like OneDrive, Google Drive, Dropbox, and iCloud are the biggest hidden speed killers. These programs sync files constantly — even when you are not actively using them — and they can consume most of your available bandwidth. Check your system tray (the icons in the bottom right corner on Windows, or the menu bar on Mac) for these apps and pause them while you work.

Open your Task Manager on Windows by pressing Ctrl+Shift+Esc. Click the Network column to sort by network usage. Any program showing consistent activity is eating your bandwidth. On Mac, open Activity Monitor (search for it in Spotlight), click the Network tab, and look for programs with high Sent or Received numbers. Close or quit the ones you do not need right now.

Streaming apps, torrent clients, and backup software also run in the background. Windows Update and macOS updates can read in the background too. Pause these while you need speed, then restart them later.

Switch from WiFi to a wired connection

WiFi is convenient but slower and less stable than a wired Ethernet cable. If your PC is near your router, plug an Ethernet cable directly into both your computer and your router. Run a speed test again. You will almost always see faster speeds and lower ping times, which means more responsive browsing and video calls.

If your PC is far from the router, a long Ethernet cable is still worth it — you can run it along baseboards or through walls. If that is not practical, move your router to a more central location in your home, or buy a WiFi extender or mesh network system to improve the signal where your PC sits.

Even if you keep using WiFi, moving your router away from walls, metal objects, and other electronics can improve speed. Routers work best when they are elevated and in an open space, not hidden in a cabinet or corner.

Restart your router and check for firmware updates

Unplug your router for 30 seconds, then plug it back in. This clears the router's memory and often restores speed without any other work. Many people skip this step, but it fixes slow internet more often than any other single action.

While your router is restarting, check whether it needs a firmware update. Log into your router's admin page by typing 192.168.1.1 or 192.168.0.1 into your browser address bar (check your router's label if neither works). Look for a Settings or Administration section and search for Firmware or Software Update. If an update is available, install it. Firmware updates improve speed, security, and stability.

After the update finishes, restart your router again by unplugging it for 30 seconds. Run another speed test to see whether the update helped.

Update your WiFi drivers on Windows or Mac

Your PC's WiFi driver is the software that lets your computer talk to your router. An outdated driver can slow your connection. On Windows, right-click the Start button, select Device Manager, and expand Network Adapters. Right-click your WiFi adapter (usually called something like Intel Wireless or Realtek), select Update Driver, and choose Search automatically for updated driver software. Windows will read and install the latest version.

On Mac, drivers usually update automatically when you run macOS updates. Open System Preferences, click Software Update, and install any available updates. After updating, restart your computer and run a speed test.

If your WiFi adapter is very old, updating the driver may not help much. In that case, a USB WiFi adapter (which plugs into a USB port) or a wired Ethernet connection will give you better speed.

Check your WiFi channel and band settings

WiFi routers broadcast on different channels, and if your neighbors' routers are using the same channel, they interfere with each other. Log into your router's admin page again (192.168.1.1 or 192.168.0.1) and look for WiFi Settings or Wireless Settings. You will see options for Channel and Band.

For the 2.4 GHz band, try channels 1, 6, or 11 — these do not overlap with each other. For the 5 GHz band, you have many more channels and interference is less common. If your router supports WiFi 6 (also called 802.11ax), use that band if your PC supports it — it is faster and handles more devices better than older standards.

Change one setting at a time, save, and run a speed test. If the new channel is slower, try a different one. Some routers have an auto-select feature that picks the best channel automatically — that is usually a good choice if you do not want to experiment.

Disable bandwidth-heavy features you do not need

Windows and Mac both have features that use bandwidth in the background. On Windows, open Settings, go to Privacy & Security, and scroll down to find Diagnostics & usage data. Set it to Required diagnostic data (the minimum). Also check Settings > System > Storage > Storage Sense and turn off automatic cleanup if you do not need it.

Disable Windows Update from downloading updates automatically while you work. Open Settings > Update & Security > Windows Update, click Advanced options, and set Active hours to the times when you use your PC most. Windows will not restart during those hours and will not read updates then.

On Mac, open System Preferences > General and uncheck Automatic updates if you want to control when updates run. You can also disable Siri suggestions and reduce visual effects, though these have smaller impacts on speed than background updates.

Frequently Asked Questions

Why is my WiFi fast on my phone but slow on my PC?

Your PC may have an older WiFi adapter, outdated drivers, or too many background programs running. Try switching to a wired Ethernet cable to test whether the problem is WiFi itself. If the wired connection is fast, update your WiFi drivers and close background programs. If it is still slow, your WiFi adapter may need replacement.

Does closing browser tabs actually make the internet faster?

Closing tabs frees up RAM and can make your computer feel more responsive, but it does not directly speed up your internet connection unless those tabs are actively loading content or playing video. Closing programs that sync files (like OneDrive) has a much bigger impact on internet speed.

Will a WiFi extender or mesh network actually improve my speed?

A WiFi extender or mesh system can improve the signal strength where your PC sits, which may improve speed if you are far from your router. However, they do not increase your total available bandwidth — they just spread the same connection over a wider area. A wired Ethernet cable is always faster if you can use one.

Should I change my DNS settings to speed up the internet?

Changing DNS (to services like Google DNS or Cloudflare) can sometimes make websites load slightly faster, but the difference is usually small — a few milliseconds. It is worth trying if you have already done the other steps, but it is not a primary fix. Your internet provider's DNS is usually fine.

How often should I restart my router?

Restart your router whenever you notice speed dropping, or once a month as routine maintenance. You do not need to restart it daily. If you find yourself restarting it more than once a week to fix slow speeds, the router may be failing and you may need to replace it.
