Hi. My name is Lester, and I am an Independent Advisor. I'm sorry that you are experiencing this issue. I'd be more than happy to assist you.
Are there any error messages or codes? When was the last time it worked without any issues? Is this a laptop or a desktop? If possible, please take a screenshot of the settings showing the missing Wi-Fi connection and attach it to your next reply. Please cover any personal or sensitive information.
In the meantime, please try the following methods:
- Run the Network troubleshooter
Click the Start Menu > Settings > Network & Internet > Status.
Select Network Troubleshooter > Click Run.
Follow the on-screen procedure, and see if that fixes the problem.
- Reboot your modem and wireless router.
- Type 'command prompt' on your search bar and right-click the result, then run as administrator
copy and paste each command(one at a time) below and hit enter:
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
Restart your PC then check
- Try network reset
Click Start Menu > Settings > Network & internet > Advanced network settings > Network reset > Select Reset now > Yes to confirm.
I hope this information is helpful. Please don't hesitate to reach out if you have any more questions. Thank you
