I'm getting ready to purchase a DSL modem and return the one issued (Arris NVG443B) by my DSL provider Frontier Communications as I am currently having problems that they refuse to address. My main concern is how it will be able to authenticate & connect to their service? I once asked for the PPP password on a tech support call due to a recurrent issue with a NetGear modem they provided losing all the config info, and they refused me that info. I'm 60 years old and know only a bit about networking. Can someone point me to a step by step doc for this process or give me a semi-simple answer? TIA
