In October our new Gen 5 modem with built in wireless was having problems connecting with my printer. I called Tech support and was on the phone HOURS with different Techs trying different solutions....
I had to enable WPS in the modem's settings in order for WPS to work. I don't know if this is the default, but once I did the WPS button worked and things would connect to it, though the button requires a bit of effort to press enough to work. With that said, it was only for a test, so I turned the WPS option back off, as I don't normally connect using that method.
With this said, if you would like to have the billing issue looked at you should post in the "myAccount and Billing" section, as the section this post is in (General Discussion) is not for support.
