Check what speed you are actually getting

Before you change anything, measure your current speed so you know whether the problem is real or perceived. Visit speedtest.net or fast.com in a web browser on the device that feels slow. These sites measure how fast data moves to and from your connection. Write down the download speed (measured in Mbps) and upload speed — you will need these numbers if you contact your provider.

Run the test at different times of day. Internet speed often drops during evening hours when more people in your area are online. If your speed is consistently lower than what you pay for, you have a legitimate complaint. If it drops only at certain times, the problem may be network congestion rather than your setup.

Test on a device connected by ethernet cable if you have one. If the wired speed is much faster than your wireless speed, the problem is your WiFi, not your internet connection itself. This distinction matters because the fixes are completely different.

Key Takeaways

  • Restart your modem and router by unplugging them for 30 seconds — this fixes slow speeds about half the time and costs nothing.
  • Move your router to a central, elevated location away from walls and metal objects, because physical obstacles block WiFi signals significantly.
  • Check how many devices are connected to your network, since each one shares your available bandwidth and background apps drain speed without you noticing.
  • Contact your internet provider with your speed test results if your measured speed is consistently lower than your plan promises.
  • Upgrade your router if it is more than five years old, because older models cannot deliver the speeds that modern internet plans provide.

Restart your modem and router

This is the first step because it works roughly half the time and takes two minutes. Unplug your modem (the device that connects to the wall outlet and your internet line) and your router (the device that broadcasts WiFi). Wait 30 seconds. Plug the modem back in first and wait for all its lights to stop blinking and settle into a steady pattern — usually 2 to 3 minutes. Then plug in the router and wait another 2 to 3 minutes for it to fully start.

During this restart, the modem clears out temporary data that can slow your connection, and the router resets its WiFi broadcast. Many internet slowdowns are caused by these devices getting stuck in a confused state, especially if they have been running continuously for weeks.

After the restart, run your speed test again. If your speed improved noticeably, you are done. If nothing changed, move to the next step.

Move your router to a better location

WiFi travels in straight lines and bounces off hard surfaces, so placement matters more than most people realize. Move your router to a central location in your home rather than tucking it in a corner or closet. Elevated placement works better than floor level — a shelf or wall mount is ideal. Keep it away from metal objects (filing cabinets, refrigerators, microwave ovens) and away from thick walls or concrete, all of which block the signal.

Distance also matters. WiFi signal strength drops significantly beyond 50 feet, and walls between you and the router weaken it further. If your router is in a back bedroom and you use the internet in the front of the house, you are fighting physics. Moving it to a hallway or central room often produces a noticeable improvement without spending any money.

If your home is large or has thick walls, a single router may not reach everywhere. In that case, a mesh WiFi system (multiple units that work together) covers more area than one router alone, but that is an upgrade decision, not a free fix.

Reduce the number of devices and background activity

Every device connected to your network shares your available bandwidth. If you have 10 devices online and only one person is actively using the internet, the other nine are still consuming speed through background updates, cloud syncing, and automatic backups. Check how many devices are actually connected by logging into your router's settings (usually accessible at 192.168.1.1 or 192.168.0.1 in a web browser — your router's manual has the exact address).

Disconnect devices you are not using. Turn off WiFi on phones and tablets when you are not actively browsing. Disable automatic updates on computers during times when you need speed — Windows and Mac both allow you to schedule updates for specific hours. Close browser tabs you are not reading; each open tab can run scripts that consume bandwidth in the background.

On your main computer, check what programs are running in the background. Open Task Manager on Windows (Ctrl+Shift+Esc) or Activity Monitor on Mac (Applications > Utilities) and look for programs using the network. Cloud storage services like OneDrive, Google Drive, and Dropbox often sync files in the background without you noticing. Pause them while you work, then resume later.

Contact your internet provider with your speed test results

If you have restarted your equipment, optimized your router placement, and reduced background activity but your measured speed is still significantly lower than what you pay for, the problem is likely on your provider's side. Call or chat with your internet provider's support line and tell them your plan speed (the speed you pay for) and your measured speed (the number from speedtest.net). Have your account number ready.

Providers sometimes throttle speeds during peak hours, but if your speed is consistently 30 percent or more below what you pay for, they should investigate. They may ask you to restart your modem again while on the call, or they may send a technician to check the line coming into your house. Some providers offer to replace your modem if theirs is old or faulty.

Document the dates and times you ran your speed tests. If the problem is intermittent, note when it happens — evening hours, weekends, specific days. This information helps the provider narrow down whether the issue is network congestion in your area or a problem with your specific connection.

Upgrade your router if it is more than five years old

Routers have a practical lifespan. A router from 2019 or earlier may not support the faster speeds that modern internet plans deliver. If your modem is new but your router is old, the router becomes the bottleneck. You can have a 500 Mbps internet plan, but an old router might only deliver 100 Mbps to your devices.

Check your router's model number (usually on a sticker on the back) and look up its specifications online. Compare the maximum speeds it claims to support against your internet plan speed. If the router's maximum is lower than your plan speed, upgrading will help. A modern WiFi 6 router (also called 802.11ax) costs between $100 and $300 and can handle speeds up to 1 Gbps or higher, depending on the model.

When you buy a new router, keep your old one as a backup. Set up the new one by following the manufacturer's instructions — most modern routers have a setup app that walks you through the process. After setup, run your speed test again to see whether the upgrade made a difference.

Consider your internet plan itself

Sometimes the real problem is that your plan speed is too low for how you use the internet. If you have five people in your household all streaming video, attending video calls, and gaming simultaneously, a 100 Mbps plan will feel slow no matter how well your equipment is optimized. Video streaming alone uses 5 to 25 Mbps depending on quality, so multiple streams add up quickly.

Check what speeds are available in your area by visiting your provider's website or calling them. Faster plans usually cost more, but the price difference is often smaller than people expect. Some areas have multiple providers competing for customers, which can lower prices. If you are in an area with only one provider, your options are limited, but it is worth asking what faster plans cost.

Before upgrading your plan, make sure your current equipment can actually deliver those speeds. A new plan is wasted money if your router cannot handle it. Upgrade your router first, test your current plan's actual speed, and then decide whether a faster plan is necessary.

Frequently Asked Questions

Why is my WiFi slow but my ethernet connection is fast?

Your WiFi signal is being blocked or weakened by distance, walls, or interference. Move your router closer to where you use it, place it in a central location, and keep it away from metal objects and thick walls. If that does not help, your router may be old or faulty and need replacement.

Does restarting my modem really help, or is that just what tech support says?

Restarting genuinely fixes slow speeds in many cases because modems can get stuck in a confused state after running continuously for weeks. The restart clears temporary data and resets the connection. It costs nothing and takes a few minutes, so it is always worth trying first.

What speed do I actually need for normal internet use?

For one person browsing, email, and video calls, 25 to 50 Mbps is usually enough. For a household with multiple people streaming video or gaming, 100 to 200 Mbps is more comfortable. The more people and devices using the internet simultaneously, the higher your plan speed should be.

Can I improve my speed by changing my WiFi channel or password?

Changing your WiFi channel can help if you live in an apartment or dense neighborhood where many routers are broadcasting on the same channel and interfering with each other. Log into your router settings and try switching to a less crowded channel. Changing your password does not affect speed but does prevent neighbors from using your bandwidth.

Is my internet provider throttling my speed on purpose?

Some providers throttle speeds during peak hours when the network is congested, but this is usually temporary. If your speed is consistently 30 percent or more below what you pay for at all times of day, contact your provider with your speed test results. They can investigate whether the problem is on their end or with your equipment.
