I purchased my SB6121 from an authorized retailer (Staples).  Recently while talking to my internet provider (Comcast), they claimed that it needed a firmware upgrade and asked me if I would allow them to do it.  They did not tell me at the time that they would be stealing control of my personally owned hardware from me.  After installing the firmware upgrade, they proceeded to tell me that there is a problem with the hardware and tried to sell me their modem.  When I log into my modem (at IP 192.168.100.1), there is no longer a “Reset All Defaults” button.  This is unacceptable and I want control of my hardware back.

Is there a way I (or you) can roll back the hacked firmware they installed and return control of my hardware to me?

Arris supports only the retail products that are available on surfboard.com but not the ISP lease products. Please contact your Internet Service Provider for further assistance.
