Please confirm the following:
* Your broadband hardware is powered-up and plugged in
Unless your hardware is powered up and connected, the checks will fail. If you are not able to set up your broadband connection right now, you can return to this point within 48 hours to begin the tests.
* You have disabled hardware and software firewalls
A firewall is a feature that blocks other Internet users from accessing your network. If you connect with a router, check the router settings to confirm that if it has a built-in firewall, it is currently disabled. If you are not sure, check the router documentation.
WTF? Are you drunk? Oh sure, I'll just switch off my firewalls. Hang on while I drop my pants and bend over too.
