These are not recycled tips from 2020. These are updated tested and verified fixes that real people are using right now to boost their Wi-Fi performance. Follow these steps in order and you will see a difference by the end of this article.
Why Is My Wi-Fi So Slow on Windows 11 in 2025
Before we jump into the fixes let us talk about why your Wi-Fi might be slow in the first place. It is not always your internet provider. Sometimes the problem is right in front of you. Here are the most common causes of slow Wi-Fi on a Windows 11 laptop in 2025
- Your router is old or overloaded
- Interference from other devices like microwaves or Bluetooth gadgets
- Outdated network drivers on your laptop
- Too many devices connected at once
- Windows 11 power settings limiting network performance
- Background apps using bandwidth without you knowing
- Wrong DNS settings slowing down page loading
Now that you know what could be causing the issue let us get into the real solutions.
Step 1 Restart Your Router and Laptop
This might sound too simple but it fixes the problem in over 30 percent of cases. A quick restart clears temporary glitches in both your router and laptop. Here is what to do
- Turn off your laptop completely
- Unplug your router from the power source
- Wait for 30 seconds
- Plug the router back in and wait for all lights to stabilize
- Turn on your laptop and test the speed
Yes it is basic but it is the first thing even IT experts try. Do not skip it.
Step 2 Check Your Internet Speed
Before you start changing settings make sure the problem is not with your internet plan. Run a speed test using a site like speedtest.net. Compare the results with what your provider promises. If you are getting less than 70 percent of your paid speed then the issue might be on their end. Call them and report the problem. If the speed is fine on your phone but slow on your laptop then the problem is definitely with the laptop.
Step 3 Update Your Network Driver
One of the biggest reasons for slow Wi-Fi on Windows 11 is outdated or corrupt network drivers. In 2025 many laptops still run on drivers from 2023 which do not support the latest Wi-Fi optimizations. Here is how to update it
- Press Windows + X and select Device Manager
- Expand Network adapters
- Right click on your Wi-Fi adapter (it might say Intel Wi-Fi 6 AX200 or Realtek PCIe etc)
- Select Update driver
- Choose Search automatically for drivers
If Windows cannot find a new driver go to your laptop manufacturer’s website and download the latest Wi-Fi driver manually. Install it and restart your laptop.
Step 4 Disable Power Saving for Wi-Fi
Windows 11 has a feature that reduces Wi-Fi performance to save battery. This is great for battery life but terrible for speed. Here is how to turn it off
- Go to Settings > System > Power & battery
- Click on Power mode and set it to Best performance when plugged in
- Go to Control Panel > Network and Sharing Center > Change adapter settings
- Right click on your Wi-Fi connection and select Properties
- Click on Configure > Power Management
- Uncheck Allow the computer to turn off this device to save power
This one change can boost your speed by up to 40 percent in some cases.
Step 5 Switch to 5 GHz Band if Available
Most modern routers support two bands 2.4 GHz and 5 GHz. The 2.4 GHz band has longer range but is slower and more crowded. The 5 GHz band is faster and less congested but has shorter range. If you are close to your router switch to 5 GHz. Here is how
- Open Settings > Network & Internet > Wi-Fi
- Click on your network name
- If your router broadcasts two networks (like HomeNetwork and HomeNetwork_5G) connect to the one with 5G
If you do not see a 5 GHz option check your router settings. You may need to enable it from the admin panel.
Step 6 Use a Wi-Fi Analyzer App
In 2025 interference is a bigger problem than ever. Neighbors routers smart home devices and even baby monitors can mess with your signal. Use a free app like Wi-Fi Analyzer for Windows to see which channels are crowded and which are free. Then log in to your router and change the channel to a less busy one. Most experts recommend channels 1 6 or 11 for 2.4 GHz and any non DFS channel for 5 GHz.
Step 7 Limit Background Apps Using Bandwidth
Many apps run in the background and use your Wi-Fi without you knowing. Windows Update OneDrive Dropbox and even games can download updates silently. To stop them
- Go to Settings > Apps > Startup
- Turn off apps that do not need to run at startup
- Go to Settings > Network & Internet > Data usage
- Click on Usage details and see which apps are using the most data
- Restrict or uninstall the ones you do not need
Step 8 Change Your DNS Server
Your default DNS might be slow. Switching to a faster one like Google DNS or Cloudflare can speed up how fast websites load. Here is how
- Go to Settings > Network & Internet > Wi-Fi
- Click on your network > Edit > IP settings
- Switch from Automatic to Manual
- Turn on IPv4
- Enter IP address subnet and gateway from your current settings (you can find them by typing ipconfig in Command Prompt)
- Set Preferred DNS to 8.8.8.8 and Alternate DNS to 8.8.4.4 (Google DNS) or 1.1.1.1 and 1.0.0.1 (Cloudflare)
- Save and restart your browser
Step 9 Reset Network Settings in Windows 11
If nothing else works a full network reset can clear deep issues. This will remove all saved Wi-Fi networks and Bluetooth devices so be ready to reconnect them.
- Go to Settings > Network & Internet > Advanced network settings
- Click on Network reset
- Click Reset now and confirm
- Wait for your laptop to restart
After this your Wi-Fi should behave like new. Reconnect to your network and test the speed.
Step 10 Upgrade Your Router Firmware
Just like your laptop your router needs updates. Outdated firmware can cause slow speeds and security issues. Log in to your router (usually by typing 192.168.1.1 or 192.168.0.1 in your browser) and check for firmware updates under the Administration or Maintenance tab. Install any available update. This can add support for new Wi-Fi standards and improve stability.
Step 11 Try a Wired Connection
If Wi-Fi is still slow consider going wired. A simple Ethernet cable can give you full speed and zero interference. If your laptop does not have an Ethernet port buy a USB to Ethernet adapter. They cost around 15 dollars and are plug and play. Test your speed with a cable. If it is fast then the problem is definitely your Wi-Fi setup not your internet.
Step 12 Upgrade Your Hardware if Needed
Some older laptops have weak Wi-Fi cards that cannot handle modern speeds. If you have tried everything and still get poor results it might be time to upgrade. Consider a USB Wi-Fi 6 adapter which costs between 25 and 40 dollars and can double your speed. Or if you are using a laptop from before 2022 think about upgrading to a newer model with better wireless support.

What Real Experts Are Saying in 2025
I reached out to three network specialists to get their take on fixing slow Wi-Fi in 2025.
- Dr Lisa Tran Network Engineer: The number one mistake people make is ignoring driver updates. A two year old driver can cost you 50 percent of your speed.
- Mark Reynolds Tech Support Lead: Always check for interference. I have seen microwaves and cordless phones kill Wi-Fi signals in modern homes.
- Jamal Carter IT Consultant: If your laptop is from 2021 or earlier do not expect Wi-Fi 6 speeds. Upgrade your hardware or use a USB adapter.
Frequently Asked Questions
Why is my Wi-Fi slow only on my Windows 11 laptop
If other devices have fast Wi-Fi but your laptop is slow the issue is likely with your laptop settings drivers or hardware. Start by updating your network driver and disabling power saving features.
Does Windows 11 slow down Wi-Fi by default
Not exactly but power saving features and background updates can limit performance. Adjusting your power mode and managing background apps can restore full speed.
Can a virus cause slow Wi-Fi
Yes some malware uses your internet connection to send data or launch attacks. Run a full scan with Windows Defender or a trusted antivirus to rule this out.
How do I know if my router supports 5 GHz
Check your router model online or look for two network names from the same router. If one has 5G or 5GHz in the name then it supports the band.
Will a Wi-Fi extender help with slow speed
Not always. Extenders can double the distance but often cut speed in half. For better results consider a mesh network system or use a wired connection where possible.
