1. Check Whether Your Internet Connection Is Actually Slow

Before changing any settings, confirm that your internet connection is slower than expected. Sometimes a website or application is the problem rather than your entire connection.

Open your browser and run an internet speed test using a reputable service such as Speedtest by Ookla or Fast.com.

Check these three measurements:

Download speed: How quickly your device receives data. This affects video streaming, downloads, and loading large files.
Upload speed: How quickly your device sends data. This matters for video calls, cloud backups, and uploading files.
Latency or ping: How long data takes to travel between your device and a server. High latency can make gaming and remote meetings feel slow, even when download speed looks good.

For example, if your internet package offers 50 Mbps but your computer consistently receives only 5 Mbps under similar testing conditions, there may be a connection problem.

However, Wi-Fi results can vary depending on your distance from the router, interference, network congestion, and the speed of the test server. Run the test two or three times before drawing a conclusion.

Also test another device. If your phone and laptop are both slow on the same Wi-Fi network, the router or internet service may be responsible. If only your Windows 11 computer is affected, focus on its software, adapter, or Wi-Fi connection.

2. Restart Your Router and Computer

Restarting your equipment is one of the simplest ways to resolve temporary network problems. A router can develop connection issues after running for a long time, while Windows may retain a network state that is no longer working properly.

Follow these steps:

Save your work and restart your Windows 11 computer.
Turn off your router using its power button, if available.
Unplug the router from its power source.
Wait approximately 30 seconds.
Reconnect the power and allow the router a few minutes to reconnect to your internet provider.
Connect your computer again and run another speed test.

If you use a separate modem and router, restart both devices. Follow your provider’s instructions if the equipment has a specific restart sequence.

Avoid pressing the router’s Reset button. A factory reset is different from a normal restart and may erase your Wi-Fi name, password, and provider-specific settings.

If the internet becomes fast again after restarting but slows down repeatedly, check for router firmware updates or contact your provider. Frequent restarts should not be necessary for a healthy connection.

3. Check Whether Background Apps Are Using Your Internet

Your internet may feel slow because another application is downloading or uploading data in the background.

Common examples include:

Windows updates
Steam, Epic Games Launcher, or other game downloads
OneDrive or other cloud storage synchronization
Large file transfers
Video streaming applications
Backup software

Windows 11 lets you check which applications are using system resources through Task Manager.

Press Ctrl + Shift + Esc.
Open the Processes section.
Look for applications showing significant network activity, if the Network column is available.
Close or pause downloads that you recognize and do not currently need.
Test your internet speed again.

You can also open Settings > Network & internet > Advanced network settings > Data usage to review data usage by application. The exact information available may vary by connection and Windows version.

Remember that an application’s total data usage does not necessarily mean it is using bandwidth at that moment.

Do not end unfamiliar system processes just because their names look unusual. If an application is downloading an update, pausing the download is safer than disabling system services.

4. Improve Your Wi-Fi Signal

A weak Wi-Fi signal is a common reason for slow internet on a Windows 11 computer.

Your internet package may be fast, but your computer cannot take full advantage of it if the wireless signal is weak or unstable.

Try these changes:

Move closer to the router.
Place the router in an open, central location.
Avoid placing it behind a television, inside a closed cabinet, or next to large metal objects.
Keep it away from devices that may cause wireless interference.
If possible, reduce the number of thick walls between the router and your computer.

You can check your Wi-Fi signal by selecting the network icon on the Windows taskbar and looking at the wireless signal indicator.

If your connection improves significantly when you move closer to the router, the issue is likely related to signal strength, interference, or the router’s coverage.

For a desktop computer, also check whether its Wi-Fi antennas are connected properly. Some desktop wireless adapters perform poorly when their external antennas are missing or positioned incorrectly.

If the router is far away, consider relocating it or using a properly configured access point or mesh Wi-Fi system rather than immediately purchasing a faster internet package.

5. Switch Between 2.4 GHz and 5 GHz Wi-Fi

Many modern routers broadcast Wi-Fi on both 2.4 GHz and 5 GHz bands. Some also support 6 GHz.

Each band has different characteristics.

Wi-Fi band	Main advantage	Main limitation
2.4 GHz	Better coverage through walls	Often more crowded and may offer lower speeds
5 GHz	Often faster at shorter distances	Signal generally weakens more quickly through obstacles
6 GHz	Can offer high speeds and less congestion	Requires compatible equipment and usually has more limited range

If your router provides separate network names for 2.4 GHz and 5 GHz, try connecting to each one and comparing the results.

For example, a computer in the same room as the router may perform better on 5 GHz. A computer several rooms away might get a more stable connection on 2.4 GHz.

If your router combines the bands under one network name, it may automatically select a band. You might need to change the router’s configuration to test them separately.

Do not assume that 5 GHz is always better. The best option depends on your distance from the router, the walls in between, interference, and the capabilities of your devices.

6. Disable Your VPN Temporarily

A virtual private network (VPN) routes your internet traffic through another server. Depending on the VPN service, server distance, encryption overhead, and network congestion, it can reduce your internet speed.

To check whether your VPN is responsible:

Open your VPN application.
Disconnect from the VPN temporarily.
Run another speed test.
Compare the results with your VPN connected.

If your speed improves significantly when the VPN is disconnected, try selecting a server closer to your location or choosing a less congested server.

Some VPN applications also include options such as split tunneling or different connection protocols. These may help, depending on the service.

Only disconnect your VPN for testing if it is safe to do so. If your workplace requires a VPN, follow your organization’s security rules.

If the connection remains slow with the VPN disconnected, continue to the next step.

7. Stop Unnecessary Windows Background Downloads

Windows 11 may download updates and other content while you’re using your computer. These downloads can compete with your other applications for available bandwidth.

You do not need to permanently disable Windows Update to solve this problem.

First, check whether an update is currently downloading:

Open Settings.
Select Windows Update.
Check whether updates are downloading or installing.
If necessary, allow the process to finish or use the available pause option temporarily.

You can also configure Delivery Optimization:

Open Settings.
Go to Windows Update.
Select Advanced options.
Open Delivery Optimization.
Review the options for downloading updates from other PCs.

Depending on your Windows version, you may be able to disable downloads from other PCs or adjust bandwidth limits.

If your connection has a limited data allowance, you can also consider setting your Wi-Fi connection as metered. Go to Settings > Network & internet > Wi-Fi, open your connected network’s properties, and enable Metered connection.

A metered connection can reduce certain background data activities, but it may also affect how Windows and some applications download updates. It is not a general internet speed booster.

8. Forget and Reconnect to Your Wi-Fi Network

Windows may occasionally have trouble with a saved Wi-Fi profile. Forgetting the network and reconnecting creates a fresh connection using the network’s current settings.

Before starting, make sure you know your Wi-Fi password.

Open Settings.
Select Network & internet > Wi-Fi.
Open Manage known networks.
Find your Wi-Fi network.
Select Forget.
Return to the available networks list.
Select your network and reconnect using the password.

Once connected, run another speed test.

This step is especially useful if your computer connects to the network but experiences unusual performance, repeated connection problems, or trouble after a router configuration change.

It will not fix an overloaded internet connection or a weak signal by itself, so compare the results rather than assuming the problem is solved.

9. Run the Windows Network Troubleshooter

Windows 11 includes network troubleshooting tools that can identify some common connection problems.

To start:

Open Settings.
Select System > Troubleshoot > Other troubleshooters.
Find the available network or internet troubleshooter, if listed.
Select Run and follow the instructions.

Windows 11 versions differ in their troubleshooting interface. You can also open the Get Help application and search for internet connection troubleshooting.

The troubleshooter may identify problems involving the network adapter, gateway, or connectivity configuration. However, it cannot fix every cause of slow internet.

If Windows reports that your connection is working normally but your speed remains low, continue with the next steps.

10. Change Your DNS Server

DNS translates website names, such as example.com, into IP addresses that computers use to communicate.

If your DNS server responds slowly or fails to resolve a domain, websites may take longer to begin loading. However, changing DNS usually does not increase the raw download speed of an otherwise healthy connection.

You can test a different DNS provider if websites take unusually long to start opening or if you suspect a DNS issue.

For example, Cloudflare offers the public DNS addresses 1.1.1.1 and 1.0.0.1. Google Public DNS offers 8.8.8.8 and 8.8.4.4.

To configure DNS in Windows 11:

Open Settings > Network & internet.
Select Wi-Fi or Ethernet, depending on how you’re connected.
Open your connection’s hardware properties or DNS settings.
Find DNS server assignment and select Edit.
Choose Manual configuration.
Enable IPv4.
Enter the primary and secondary DNS addresses from your chosen provider.
Save the changes.

The exact settings screen may vary by Windows version.

If the change causes problems, return to the same menu and restore the previous or automatic DNS settings.

For a broader DNS troubleshooting process, read Hammrly’s guide on how to fix DNS server not responding on Windows 11.

11. Update Your Network Adapter Driver

Your network adapter driver allows Windows to communicate with your Wi-Fi or Ethernet hardware. An outdated, incompatible, or faulty driver can cause poor performance, unstable connections, or other network problems.

To check for driver updates:

Right-click the Start button.
Select Device Manager.
Expand Network adapters.
Find your wireless or Ethernet adapter.
Right-click it and select Update driver.
Choose Search automatically for drivers.

Windows may report that the best available driver is already installed. That does not always mean the manufacturer’s latest version is installed.

If the problem started after a Windows update or driver change, open the adapter’s Properties > Driver tab. If the option is available, Roll Back Driver may help restore the previous version.

You can also check the computer manufacturer’s support website for your exact model and download its recommended network driver.

For a laptop, use the manufacturer’s model-specific driver where possible. For a custom-built desktop, check the motherboard or wireless adapter manufacturer’s website.

Avoid downloading drivers from unfamiliar websites or using random driver-updater utilities.

12. Check Your Network Adapter Settings

Some network adapters have power-saving options that may affect connectivity on certain systems.

You can inspect these settings without changing everything at once.

Open Device Manager.
Expand Network adapters.
Right-click your Wi-Fi adapter and select Properties.
Open the Power Management tab, if available.
If the option to allow the computer to turn off the device to save power is present, test disabling it.
Select OK and check your connection again.

Not every adapter has this tab, and changing this setting may increase power consumption.

You may also see an Advanced tab containing adapter-specific options. Their names and effects depend on the manufacturer. Avoid changing settings you do not understand, particularly options related to wireless standards, roaming, or transmit power.

If the problem occurs mainly when the laptop is running on battery power, compare its performance while plugged in. This may help identify whether power management is involved.

13. Reset Windows Network Settings

If your internet remains slow after trying the previous fixes, Windows network settings may be misconfigured.

Windows 11 includes a network reset feature that reinstalls network adapters and restores many networking settings to their defaults.

Before using it, be aware that you may need to reconnect to Wi-Fi, reconfigure some networking software, or set up a VPN again.

To reset the network:

Open Settings.
Select Network & internet.
Open Advanced network settings.
Select Network reset.
Review the warning and choose Reset now.
Restart your computer if prompted.
Reconnect to your network and test the speed.

Network reset is more disruptive than restarting your router or forgetting a Wi-Fi network. Use it after simpler troubleshooting steps, not as the first solution.

You can also try refreshing the network configuration from an administrator Command Prompt. Open Start, search for cmd, select Run as administrator, and execute the following commands one at a time:

ipconfig /flushdns
ipconfig /release
ipconfig /renew

The first command clears the DNS resolver cache. The other two request a new IP configuration from the network.

Your connection may temporarily disconnect while these commands run. If you are using a static IP address or a specialized work network, check with your administrator before making changes.

14. Test Your Connection Using an Ethernet Cable

If possible, connect your Windows 11 computer directly to the router using an Ethernet cable.

Run the same speed test over Ethernet and compare the results with Wi-Fi.

This comparison is useful because it helps separate wireless problems from broader internet issues.

If Ethernet is fast but Wi-Fi is slow: The likely causes include wireless interference, poor signal strength, router placement, or a problem with your computer’s wireless adapter.

If both Ethernet and Wi-Fi are slow: The issue may involve your internet provider, router, modem, background traffic, or computer configuration.

Make sure the Ethernet cable and ports support the speed you expect. A damaged cable or a port negotiating at a lower link speed can also restrict performance.

If you do not have an Ethernet port, a compatible USB-to-Ethernet adapter may allow you to perform this test.

15. Check Your Browser for Performance Problems

Sometimes the internet seems slow because a particular browser is struggling.

For example, a website may load slowly in your usual browser but open normally in another browser. This can happen because of extensions, cached data, browser settings, or website-specific issues.

Try the following:

Open the same website in another browser.
Test it in a private or incognito window.
Temporarily disable unnecessary extensions.
Close tabs that are using substantial resources.
Update your browser to its latest supported version.

If the website works properly in another browser, investigate your original browser before changing your network settings.

Be careful with extensions that promise to accelerate browsing, block network activity, or route traffic through their own servers. Some may introduce additional delays.

Also remember that a slow website does not always indicate a slow internet connection. The website’s own servers may be overloaded or experiencing an outage.

16. Check Whether Your Router or Internet Plan Is the Limitation

If several devices are slow, your computer may not be the problem.

Routers have limits on how much traffic they can handle, and internet connections can become congested when many people stream videos, download games, or upload large files simultaneously.

Try testing your connection when fewer devices are active.

You can also check your router’s administration page for connected devices and usage information, if your model provides it. Change the router password if you discover devices you do not recognize, and use WPA2 or WPA3 security where supported.

Next, compare your speed-test results with the speed included in your internet package. Keep in mind that advertised speeds are often maximum or typical rates under specified conditions, not a guarantee that every Wi-Fi test will reach the same number.

If your speed is consistently far below the expected range, record a few test results at different times and contact your internet service provider. Ask whether there is an outage, line fault, signal issue, or congestion affecting your connection.

Do not upgrade your package until you have checked whether the existing connection is delivering the performance you already pay for.

17. When Should You Scan for Malware?

Malware is not the most common explanation for slow internet, but suspicious software can sometimes consume bandwidth or interfere with networking.

Consider a security scan if you also notice unfamiliar applications, unexpected pop-ups, unexplained uploads, or other unusual computer behavior.

To perform a basic scan:

Open Windows Security from the Start menu.
Select Virus & threat protection.
Choose Quick scan.
Follow any recommendations provided by Windows Security.

If the symptoms continue or you have a specific reason to suspect infection, consider a more thorough scan.

Avoid installing multiple antivirus applications that run real-time protection simultaneously. They can create conflicts and consume system resources.

Frequently Asked Questions

Why is my internet slow on Windows 11 but fast on my phone?

Your computer may have a weak Wi-Fi signal, an outdated network driver, a power-management issue, or background applications using bandwidth. Compare both devices in the same location and on the same Wi-Fi band before changing settings.

Why is my internet slow even though the Wi-Fi signal is full?

Signal strength does not measure your internet speed. Your router may be congested, your provider may be experiencing problems, or an application may be consuming bandwidth. Run a speed test and compare results across devices.

Does changing DNS make internet faster?

It can improve the time needed to resolve website names in some situations, but it generally does not increase download or upload throughput. If large downloads are slow, investigate your Wi-Fi, router, adapter, and internet service first.

Can Windows updates cause slow internet?

Yes. Updates and other background downloads can temporarily compete for bandwidth. Check Windows Update and other download applications, but do not permanently disable security updates to improve speed.

Why is my internet slow only at night?

Your provider’s network may become congested during busy hours. Home network usage can also increase when several people stream or download content. Test at different times and share the results with your provider if the slowdown is consistent.

Should I reset my router to fix slow internet?

Try a normal restart first. A factory reset erases configuration and may require you to set up the router again. Only perform a factory reset when simpler troubleshooting fails and you know how to restore the necessary settings.

Will upgrading my internet package fix slow Wi-Fi?

Not necessarily. A faster package will not solve a weak wireless signal, faulty adapter, damaged cable, or overloaded router. Confirm that your existing connection is delivering the expected speed before paying for an upgrade.

Final Thoughts

Slow internet on Windows 11 can have several causes, so the best solution depends on what your tests reveal.

Start by checking your actual speed and comparing it with another device. Restart your router, pause unnecessary downloads, improve your Wi-Fi signal, and check whether a VPN or browser extension is affecting performance.

If the problem continues, investigate your network adapter driver, DNS configuration, and Windows network settings. Testing through Ethernet is particularly helpful because it can show whether the slowdown is limited to Wi-Fi or affects your broader internet connection.

You do not need to apply every fix. Work through the steps in order, test after each meaningful change, and keep track of what improves the connection. That approach makes it easier to identify the real cause without changing settings unnecessarily.
