  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?

  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.

    • 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.

  4. I too am shopping for my own modem/wifi combo and I will also need voice for Suddenlink service. Will the Motorola MT7711 work?
