  1. I am looking at an ARRIS SURFboard SBG6900-AC to use when in Arizona for the winter with sudden link and use in Montana with century link the other half of year. Will this work?

          1. Update: Suddenlink says the ARRIS SURFboard SBG6900-AC “should” work with their network, but the modem does not appear on their official compatibility list.

  2. I’m in the process of buying my own equipment I have suddenlink internet, Netgear CM500 is all I need or I need something else? Thank you.
