Cox did not bother to send out notices to its customers as I am certain comcast doesnt either -
When they updated their systems the cable modem I had while only 2 years old basically became obsolete - My speeds were down below 512 and I kept calling screaming daily ~ until finally I got someone on the phone who knew wtf he was doing and he asked me for the modem model # I gave it to him and he said theres your problem you need a new modem I went right down and bought one had them provision it and right away up to 12 mbps downloads amazing a dated modem did that but not surprising to me:nobody:
