I just moved in to a new apartment. I had CenturyLink at my old place for a few years, and the cable modem I purchased before that was never used (SB6120).
Ordered 50mbps Blast HSI, then tried to set it up myself. Receive->Solid. Send->Solid. Online->Blink..then eventually it power cycles itself and tries again.
It has the SB6120-1.0.1.8-SCM02-NOSH firmware still on it from April 2009, which Comcast's CMTS apparently has a problem registering
I had a SB5101 lying around too, which syncs up right away. I temporarily had comcast register the old SB5101's MAC and it works fine, except I do not get full speeds obviously since it is DOCSIS2.
Is there any way to get my SB6120 FW updated? It is long out of warranty and right now is completely useless and I really want full speed instead of 30mbps
