Hi,
Thank you for writing to Microsoft Community Forums.
I understand that you are facing high ping issues after Windows updates. For further clarity on the issue, please respond to the questions below.
- Which Windows updates were installed recently?
- What is the build version of Windows 10 are you using currently?
- What happens when you try to connect to 2.4GHz network? Do you receive any error?
To check which updates were installed recently go to Settings > Update & Security > Windows update > View installed update history
Refer the article Which version of Windows operating system am I running?
Meanwhile, I would suggest you to try resetting the network settings and see if that helps.
- Press Windows + S key together and type CMD.
- Now right click on it and select Run as administrator.
- Accept the UAC prompts.
- Type in the following commands one by one and hit enter: netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns 5. Restart the PC.
You can also refer the article Fix network connection issues in Windows and see if that helps.
If the issue persist, please get back to us with the results of the troubleshooting steps to assist you further.
