Good night. If you've factory reset your DSL modem then you'll need to log in and setup the connection again. You will have to get in touch with FLOW so that they may provide you with the various settings as they are not set in stone. You will also need your DSL username and password to get back on. Once you have your bill they will be able to provide you with the details using your CIS PIN which is on your printed bill. I'm assuming you have a modem like the one below.

Post back your results once you get through. If you have a FLOW mobile just dial 100 and follow the instructions. If you don't have a FLOW mobile then use your land line by calling 1-888-225-5295.
Knowing the solution doesn't mean knowing the method. Yet answering correctly and regurgitation are considered "learning" and "knowledge".
