The world is moving fast and one of the main ingredients in this mix is the Internet. From self-driving cars to playing games in real-time is possible because of the fast internet. However, if this ingredient becomes sluggish, we must take action. Therefore, in this article, we will explore some methods to increase your internet speed on a Windows 11 PC.
Increase the Internet Speed on your Windows 11 PC
Follow the following suggestions to improve your Internet Speed:
- Allow your Computer to receive more data
- Add a Default TTL
- Close conflicting applications
- TCP Extension for High Performance
- Scan for Virus & Malware
Let’s examine them in detail.
1] Allow your Computer to receive more data
In this section, we will discuss the I/O Request Packet Stack Size. If you want your computer to receive more data at a single time then you have to modify IRPStackSize. IRPStackSize (I/O Request Packet Stack Size) represents how many 36-byte Receive buffers your system can use simultaneously. This tweak will not be helpful if you have a very slow connection.
To modify IRPStackSize you need to be obedient to the steps that we have mentioned below:-
Hit Win + R, type “regedit” and click OK to launch Registry Editor.
Navigate using the following route:-
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
Right-click on Parameters> New> DWORD 32.

Name it “IRPStackSize” and change the value to 32 (Decimal).

After setting this up, restart your computer to further enhance your internet speed.

2] Add a Default TTL
TTL, or Time To Live, is a feature in Windows that defines the time assigned by your router to a packet to remain in the air. The default time assigned by Windows is 128 milliseconds.
This feature can cause your computer to lag as it waits for packets that it will never receive. Therefore, adding a default TTL can help in making your internet experience lag-free.
To add a default TTL you need to follow the prescribed steps:-
Hit Win + R, type “regedit” and click OK to launch Registry Editor.
Navigate using the following route:-
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
Right-click on Parameters > New > DWORD (32-bit) Value, rename it to DefaultTTL.
Double-click on DefaultTTL and change its value to 64 (or any value between 1-255) Decimal.
After this, restart your computer and see if the issue persists.

3] Close conflicting applications

There are a lot of applications running in the background that can cause strain over your network connection. These applications can be stopped for a while. You need to check which of then could be using the internet connection and then stop them. Security software is, of course, to be excluded. Therefore, in this section, we are going to check the applications and then stop it for a temporary bump up in internet speed.
Hit Ctrl + Alt + Delete and select Task Manager from the security options.
Click the Memory tab> right-click on the task that is eating your memory> End Task.
This will end that task for a bit so that you will be able to enjoy fast internet for a bit. If that task is not important to you then you should uninstall that application.
To uninstall the application follow the prescribed steps:-
- Hit Win + X> Settings.
- Click on Apps.
- Search the app that is consuming your memory, select it, and then click Uninstall.

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
