Impossible to update Microsoft Security Essentials

I try to manually update Microsoft Security Essentials and it fails and says "Virus and spyware definitions: connection failed." Security Essentials could not complete the virus and spyware definitions update 08/27/2012, 14:04 because of a network connectivity or Internet problem. "I also tried to download the definitions manually in a file and installed, but there is no clear Security Essentials of the error. Windows Update will not work for updating the definitions either. I tried to disable the user account control, but that did not help. I have the "Check for the latest spyware and virus definitions before running a scheduled scan" on. I don't have any other antivirus real-time protection software. I recently had a problem with my internet connection with wireless devices. I turned off the password and then it back on to my router and that fixes the problem. Please and thanks in advance.
