Start with the devices and apps slowing you down

The fastest internet speed means nothing if your devices are clogged with background tasks. Before you call your provider or buy new equipment, spend ten minutes closing what you are not using. On Windows, open Task Manager (press Ctrl+Shift+Esc), click the Processes tab, and look at the CPU and Memory columns. Anything using more than 10 percent that you did not open yourself — software updaters, cloud sync programs, antivirus scans — can be paused or closed. On Mac, open Activity Monitor (search for it in Spotlight), click the CPU tab, and do the same.

Browser tabs are a second culprit. Each open tab uses memory and can run scripts in the background. Close tabs you are not reading. If you have more than fifteen open, your browser is likely slowing down your whole machine. Streaming video in one tab while you work in another will cut your speed noticeably — the video player is consuming bandwidth even if you are not watching it.

Restart your computer and your router. This sounds basic because it works. A router that has been on for weeks accumulates temporary files and gets warm. Unplug it for thirty seconds, plug it back in, and wait two minutes for it to fully restart. Then restart your computer. This clears out the junk that slows both devices down.

Key Takeaways

  • Close background programs and browser tabs before testing your speed, because they consume bandwidth and memory even when you are not using them.
  • Move closer to your router or remove physical barriers like walls and metal objects between you and it, since distance and obstruction cut wireless speed in half or more.
  • Switch to the 5 GHz band on your router if your device supports it, which is faster than 2.4 GHz but does not travel as far through walls.
  • Update your router's firmware through its settings page, and check that your device drivers are current through Windows Update or Mac Software Update.
  • If your speed is still far below what you pay for, contact your provider to check for line problems or service issues in your area.

Move closer to your router and remove obstacles

Wireless speed drops sharply with distance and physical barriers. If you are testing your speed from another room, move your device to the same room as the router. You should see an when ready improvement. Walls, especially those with metal studs or pipes, block the signal. Microwaves and cordless phones also interfere with the 2.4 GHz band that most routers use by default.

Position your router in a central, elevated location — on a shelf or wall mount rather than on the floor or inside a cabinet. Routers broadcast in all directions, so height helps the signal reach other rooms. Keep it away from the microwave and away from metal objects like filing cabinets. If your router is in a closet or behind a door, moving it to an open area can double your speed.

If you cannot move the router, move yourself. Sit closer to it while you work, or use a wired connection (see below). This is the fastest troubleshooting step and costs nothing.

Switch to the 5 GHz band if your device supports it

Most routers broadcast on two bands: 2.4 GHz and 5 GHz. The 2.4 GHz band travels farther through walls but is slower and more crowded — your neighbors' routers are also on it. The 5 GHz band is faster but does not travel as far. If you are in the same room as your router, switching to 5 GHz can noticeably speed things up.

Check your router's settings page. Open a web browser, type 192.168.1.1 or 192.168.0.1 into the address bar, and log in (the default password is usually on a sticker on the router itself). Look for a Wireless or WiFi section. You should see two network names listed — one ending in 2.4G or 2.4 GHz, and one ending in 5G or 5 GHz. Disconnect from the 2.4 GHz network and connect to the 5 GHz one instead.

If you do not see a 5 GHz option, your router does not support it, or it is turned off. Older routers only have 2.4 GHz. If your device does not show the 5 GHz network even though it is listed in the router settings, your device may not support it — check your device's manual or search for its model number plus "5 GHz support".

Use a wired connection instead of wireless

Ethernet cable is always faster than WiFi. If your device is near your router, plug in an Ethernet cable. You will see an when ready speed increase, sometimes double or triple. This is the single most reliable way to get the speed your provider promises.

If your device does not have an Ethernet port (many laptops and tablets do not), you can buy an adapter. For USB-C devices, search for "USB-C to Ethernet adapter" on any retailer site — they cost ten to twenty dollars. For older USB ports, search for "USB to Ethernet adapter". Plug the adapter into your device, plug the Ethernet cable into the adapter, and plug the other end into your router.

You do not need to run cable through your whole house. Even plugging in for an hour while you read a large file or stream video will show you what your connection is actually capable of. If your speed is much faster on Ethernet than on WiFi, the problem is wireless interference or distance, not your internet service.

Update your router firmware and device drivers

Router firmware is the software that runs your router. Manufacturers release updates that fix bugs and improve performance. Log into your router's settings page (192.168.1.1 or 192.168.0.1), look for a System, Administration, or Maintenance section, and check for firmware updates. If one is available, install it. The router will restart, which takes a few minutes.

On your computer, check for driver updates. On Windows, open Settings, go to Update & Security, and click Check for Updates. On Mac, open System Preferences, go to Software Update, and install any available updates. Drivers are the software that let your operating system talk to your network card. Outdated drivers can slow your connection.

These updates happen in the background and you do not need to do anything after starting them, but they can take fifteen to thirty minutes. Do this when you are not trying to work.

Check your internet plan against what you are actually getting

You pay for a certain speed — usually measured in Mbps (megabits per second). Your provider should deliver close to that speed during normal use. Run a speed test on a wired connection (Ethernet is important here) when no one else in your house is using the internet. Go to speedtest.net, click Go, and wait for the test to finish. Write down the read speed.

Compare it to your bill. If you pay for 100 Mbps and you are getting 80 to 100 Mbps, that is normal — you will not always hit the exact number. If you are getting 30 Mbps when you pay for 100 Mbps, something is wrong. Check whether your provider is having outages in your area by searching "[your provider name] outage" plus your city. If there is no outage, contact your provider's support line. They can check your line for problems and may send a technician to test the connection at your house.

Before you call, have your bill handy and know what speed you are supposed to be getting. Tell them you ran a speed test on a wired connection and what number you got. This saves time and makes it clear you have already done basic troubleshooting.

Reduce the number of devices connected at once

Every device on your network shares the available bandwidth. If you have ten devices streaming video, downloading files, or running updates simultaneously, each one gets a smaller slice. Disconnect devices you are not using. Turn off WiFi on your phone if you are not actively using it. Pause cloud backup and software updates on computers while you are working.

Some routers let you see which devices are connected and how much bandwidth each is using. Log into your router settings, look for a Devices, Connected Devices, or Clients section, and you will see a list. If something is using a lot of bandwidth and you do not recognize it, it may be malware or a neighbor's device that has your WiFi password. Change your WiFi password in the router settings if you suspect this.

Streaming services, video calls, and large downloads are the biggest bandwidth users. If someone in your house is streaming 4K video while you are trying to work, that is why your speed feels slow. Ask them to pause it, or wait until they are done.

Frequently Asked Questions

Why is my speed test fast on Ethernet but slow on WiFi?

Wireless interference, distance from the router, or too many devices on the 2.4 GHz band. Move closer to the router, switch to 5 GHz if available, or remove obstacles between you and it. If the problem persists, your router may be old or failing.

Does restarting my router really make a difference?

Yes. Routers accumulate temporary files and memory leaks over weeks of continuous use. Unplugging it for thirty seconds clears this out. If your speed is slow every afternoon, try restarting your router at that time — it often helps.

Can I make my internet faster by changing my WiFi password?

Only if someone without permission is using your network. If your password is weak or default, neighbors or passersby may be connected. Change it to something strong in your router settings. This frees up bandwidth for your own devices.

What speed should I actually expect?

You should get 80 to 100 percent of the speed you pay for during normal use. If you pay for 100 Mbps, expect 80 to 100 Mbps on a wired connection with no other devices using the network. Wireless will be somewhat lower depending on distance and interference.

Is my router too old to support fast speeds?

Routers older than five years may not support newer standards. If you have tried all these steps and your speed is still far below what you pay for, your router may be the bottleneck. Check its model number and search for its maximum supported speed, or contact your provider — they may offer a newer router.
