A:AnswerThis is a cable modem only. For compatibility with DSL you need a modem that has a phone line port. Centurylink should provide that to you for a small rental fee.
A:AnswerWow discontinued support for DOCSIS 3.0 4×4 or 8×4 channel bonded cable modems, so this would not work, but please check with the customer service for a list of approved modems.
A:AnswerThis modem does not have VPN software included with this modem and I have purchased this model twice. When it comes to the Netgear brand I encountered VPN software with one of their routers.
