Hi,
try to reset network connections: Open PowerShell or CMD and run as administrator, copy and paste the following commands by pressing enter at the end of each command line:
netsh winsock reset
netsh int ip reset
netsh advfirewall reset
ipconfig /flushdns
Restart the computer at the end of all commands.
If that doesn't work, try deleting all WiFi network profiles:Start>Settings>Network and Internet>Wi-Fi>Manage known networks,select all network profiles and click Cancel or Forget.
Then reconnect by re-entering the WiFi password correctly.
