    Cox Cable problem

    For the past several months, things have been super. About 4 weeks ago an odd problem started cropping up.

    The cable modem lights would be all green. I'd even have the yellow activity light blinking. However, I would no longer be able to get to the internet. Not from any of my computers. My vonage phone would also go down. However, if I power cycled the modem, it would usually fix itself. Often if I just waited for a few minutes, it would recover on its own.

    On my own, I went ahead and did all the standard diagnostic stuff... replacing wiring, bypassing my firewall and jacking a computer directly into the cable modem.

    None of that worked. It came down to either a failing modem, a bad cable connection, or faulting gear on Cox's side. I figured it was most likely the modem, especially as Cox had ripped up and replaced the majority of the gear from the pedestal out to the street for me about a year ago.

    So, I had the modem replaced. The problem has not gone away. In the past 2 weeks, I have had had 5 Cox technicians (including one "tech supervisor") out. None of them could figure it out. All of them wanted to blame my gear, the cable lines in my apartment, etc etc. Anything but their own gear.

    However, I've already ruled out my gear. And they've certified that my connection strength is excellent.

    Their technicians are badly undertrained, and I'm hoping someone here may have some idea what these cable modem logs mean.

    If it helps, I have a Motorolla SB5101 and live in Phoenix. I am a Cox Cable subscriber.

    do you have splitters that you lines connect into does the line for the internet hook into any splitters in anyway? the splitter itself can be bad replacing the spliter is easy but you want the cable guy to do it
