From reading through your manual

you can't just change the password in any way without knowing the previous password. There is no "forgot password" option.

So, you can try and figure out the info for your ISP if you need it, and then do the reset to factory settings and write the password down somewhere if you may end up forgetting it.

Depending on the ISP, you may not need any additional information. For example, my ISP sets everything up to go to a ethernet connection port in my wall and that is it. There is no additional info or anything for my connection.
