Wifi very slow on laptop, but ok on other devices - Windows 10

Hi,

Welcome to Microsoft Community. Your interest in Windows 10 is much appreciated. 

Try the below methods and check if the internet connection works fine on laptop:

Method 1:

I would suggest you to run the “Internet Connection and Network Adapter troubleshooter” to diagnose the exact issue.
Follow the steps mentioned below:

1. Open Control Panel.
2. Type “Troubleshooting” in the search box and hit enter.
3. Select “Network and Internet” option.
4. First select “Internet connections” troubleshooter.
5. Follow the on-screen instructions.
6. Then select “Network Adapter” troubleshooter and then follow the on-screen instructions.
   
   

Method 2:
If the issue persists, I would suggest you to disable security software temporarily and check.

Note: Once you are done with the troubleshooting, ensure that you have checked the option Turn on security software under settings tab.

Hi Annu

I've had the same problem as Panayiotis1984. Upgraded to Windows 10 on my Lenovo from windows 8.1 - now the wifi is painfully slow. The wifi still works fine on my other devices (smartphone etc).

I tried the steps that you suggested but they did not bring an improvement.

Any other suggestions?

Michael
