Error 676 usually occurs when a
Windows PPPoE connection is used when there is a router connected to
your DSL modem (or your DSL modem has a built in router). To fix the
issue:
- Open Internet Explorer and select Tools/Internet Options.
- Click the Connections tab at the top of the Internet Properties windows.
- Place a dot next to Never Dial a Connection.
- Click OK, then close Internet Explorer.
You should now be able to connect to the Internet.
