SB 6190 Not approved by Spectrum

Although Spectrum/Charter has previously approved this modem, they will no longer facilitate new activations for this model. We suggest returning it to your place of purchase and exchanging it for our SB8200 or S33. We apologize for any inconvenience this may cause.

Had it for 2 years so no receipt. Had to buy new. Not  happy with the blindside

The SB6190 typically comes with a 2-year warranty. If your device is still under warranty, I recommend visiting www.arris.com/consumersupport to contact Arris technical support for further assistance.

If the modem is out of warranty, I would suggest purchasing a new modem that supports DOCSIS 3.1 for better performance and compatibility.
