Try to remove the legacy connection settings in the registry and check if you have the same error as mentioned below in the Sylink log:

********************
Locate and backup this registry key:
Locate HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Connections
Then, remove these two entries:
HKEY_USER\.DEFAULT\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Connections\DefaultConnectionSettings
HKEY_USER\.DEFAULT\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Connections\SavedLegacySettings
Reboot and see if it makes any difference.
