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?
No, this will not work. Suddenlink requires a cable modem and CenturyLink requires a DSL modem (two different technologies).
The ARRIS SURFboard SBG6900-AC is a cable modem, but not currently compatible with Suddenlink. You will need two different modems for your use (please refer to each company’s approved modems page).

Not true I am currently with Suddenlink and am using the 6900AC
Thanks for the reply, Aron. Contacted Suddenlink – waiting for a response on this.
Update: Suddenlink says the ARRIS SURFboard SBG6900-AC “should” work with their network, but the modem does not appear on their official compatibility list.

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.
You are correct, you will only need the NETGEAR CM500 modem to connect to the internet.
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.
