How to disable TCP Auto-Tuning

[Anikait]

hie,
I am facing certain network connection issues relating slow network loading due to which I am not able to open and load some websites or webpages using Internet Explorer or Firefox, where the blue loading bar keeps running for a long time, but the pages fail to load. The problem is likely due to TCP auto-tuning settings. I need to disable TCP auto-tuning. How can I do this ?
plz help....

First, you will need to check the current status of TCP Auto-Tuning settings
For this,

• open elevated command prompt with administrator’s privileges.
• type the following command : netsh interface tcp show global
• press Enter

The system will display the following text, where you can check on the Auto-Tuning settings:

———————————————-
Receive-Side Scaling State : enabled
Chimney Offload State : enabled
Receive Window Auto-Tuning Level : normal
Add-On Congestion Control Provider : none
ECN Capability : disabled
RFC 1323 Timestamps : disabled

To disable TCP Auto-Tuning

• open elevated command prompt with administrator’s privileges.
• type the following command : netsh interface tcp set global autotuning=disabled
• press Enter

To re-enable TCP Auto-Tuning

• open elevated command prompt with administrator’s privileges.
• type the following command : netsh interface tcp set global autotuning=normal
• press Enter

To disable TCP/IP auto-tunning, in the "elevated" command prompt, type:
netsh interface tcp set global autotuning=disabled

In order to verify that TCP/IP auto-tunning is disabled, in the "elevated" command prompt, type:
netsh interface tcp show global. This will result the current TCP/IP Auto-tunning settings. You can check and confirm the disability of TCP/IP auto-tunning from here.

However, to restore the default, type netsh interface tcp set global autotuningl=normal
