Windows 7: My Windows 7 has lost its internet connection

My Windows 7 has lost its internet connection

My Windows 7 desktop PC has lost its internet connection. It is connected over wi-fi.

I tried doing this in CMD:

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
NETSH winsock reset catalog
NETSH int ipv4 reset reset.log
NETSH int ipv6 reset reset.log

This did not work.

I also get an error dialog on startup that says:
The program can't start because DNSAPI.DLL is missing...

Yet dnsapi.dll is in the Windows/System32 folder.

Is there any software that can fix this?

Can anyone suggest ways to restore the connection?

Thank you for your help.

I changed from wireless to an ethernet wire.

I cannot ping my router.
