  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.

  3. Anyone know if the Arris SB8200 is approved by Suddenlink yet ? This is a DOCSIS 3
    .1 Modem but fully backwards compatible. Thanks. What is up with the Intel Puma Chip set ? Gee whiz folks.

    1. The ARRIS SB8200 may work in your local area. You can contact Suddenlink on their site to find out – give them your address.

      Yes, the Intel Puma chipset is an absolute mess for the modem industry – made worse by continuing to sell these defective products on the market years after the defective discoveries.
