“Is the arris sb8200 compatible with spectrum 300 mb internet service.”

1-3 of 3 Answers

• The Arris SB8200 is overkill for a 300 MB service and it is not listed on the authorized list from Spectrum. https://www.spectrum.net/support/internet/compliant-modems-charter-network/ An appropriate DOCSIS 3.0 device should be more than adequate and save you significantly. Avoid anything with the highly problematic Puma 6 chipset such as the SB6190 or CM7000

  I would recommend:

  • 
    NETGEAR - 24 x 8 DOCSIS 3.0 Cable Modem - Black

• They will provision it if you call in, but the firmware is not going to work 100% of the time so you will risk random downtime/outage. Reseting the unit typically fixes this. Spectrum does not support the 3.1 (blue light indicator) on this in all areas, does not work where I live.

• We don’t have Spectrum in Colorado but is compatible with Xfinity. It seems faster and more stable than the modem they used to charge for.
