Now what follows is likely to only benefit you if you have noticed the Internet running slower since you updated. If things seem no different then you don’t need to proceed beyond this point. If you suspect that your internet should be faster than it is, then it might still be worth investigating the potential cause.
The problem, if it exists, could be down to a feature called Window Auto-Tuning which Microsoft first introduced in Windows Vista and has included in every version of its operating system since, including Windows 10.
Window Auto-Tuning improves performance for programs which receive TCP data over a network, and it’s enabled by default.
Ghacks points out that while it may be beneficial for some users, for others it can cause slower connections and data transfers.
To manage the Window Auto-Tuning feature, check that it’s on by following these steps:
- Go to Start, type cmd, right-click the Command Prompt entry and select Run as administrator.
- OK the UAC prompt.
- In the window, type netsh interface tcp show global
Look for Receive Windows Auto-Tuning Level. If it says Normal that means it’s running.
Once the feature is disabled, try using your internet connection again and see if that’s fixed the problem. If it hasn’t, or things are actually worse, then you should re-enable it.
In the command prompt, type netsh int tcp set global autotuninglevel=normal and hit enter.
