CM600 firmware not upgraded by Time Warner Cable
I wanted to upgrade the existing firmware (V1.01.05) of my cable modem (CM600). Netgear website says that for Time Warner Cable (TWC) I should have V1.01.12 and that I cannot upgrade manually. I h...
Hi Sponger -
Sorry to hear you are in the same boat as me. But, it does give me some satisfaction that I'm not the only one who fell into this Netgear-TWC quagmire. I don't know why TWC would say they can't update our modems because they can't access them. If they can't send a signal down the line to update the firmware then I would be more than happy to bring my modem into any TWC office for a hands-on update. Seems like two companies throwing a lot of B.S. That's why I say DO NOT BUY. If Netgear will not update their equipment and their directions to get updated from our ISP doesn't work then why buy or use Netgear equipment?
I did actually talk to "advanced support" on the phone yesterday, a very nice rep I might add. The rep asked the reasons why I wanted to update the modem and I stressed to her the importance of keeping a modem upgraded for security and performance, also offering to give TWC temporary access to my modem's admin page to perform the upgrade if necessary. She asked if I was having issues with the modem and I did mention to her that every once in a while the modem would lose signal and have to be rebooted. At this point I am waiting to hear back, but I figured I would not get a reply until the work week.
Hi Sponger - you're right about the signal dropping out. That's what got me started with all this "updating" nonsense. At first, I updated my Intel, Microsoft and Dell drivers and that helped a lot in stopping the dropouts. But, I'm still having problems and wanted to finish the project by updating my new store-bought modem. That's when I found out about the firmware updating nightmare. Keep posting. You have a keener mind than I and you expressed yourself and the problem in a concise and clear manner. You've also made it to Tech Support which no one else has managed to do.
I will keep you updated once I receive a call from Time Warner ... I guess I am not that confident in a solution at this point based on everyone's response and experiences.
Hello sponger85
With all modems on cable internet none of them can be manually updated the ISP updates all the modems and the manufacturers of the modems all send there FW to the ISP to approve and make changes and the ISP pushes it via there servers when they are ready to. But if you are having disconnect issues you should check your power levels and snr. Another thing to check is the modems logs if you are seeing T4 and T3 timeouts show up when you are losing internet this says there is a line issue of some sort and you should get the ISP to check the lines. Also if you have cable splitters on the modem try to remove them and connect the modem directly to the outlet see if the connection improves.

Hi Darren -
What you say is the same as the Netgear website - BUT IT ISN'T TRUE. Read the complaints. Netgear won't update our modems and Time Warner Cable says they can't update them either. As for my power levels, about the same time that I bought the modem, I had a TWC technician out to check on another problem. He replaced all my cable from the street and into my house. He even installed a 0db amplifier to make sure my levels were strong and consistent. You cannot escape the fact that Netgear is selling a product that can soon become obsolete as the cable companies update their drivers and the Netgear modem can't keep up. It's the same as if we were running Windows XP and trying to surf the Internet. There are too many updates security and otherwise that would make us vulnerable to poor service.
One other point from the Netgear website, I haven't checked specifically but I think SOME modem models CAN be updated by Netgear. It's just that THIS CM600 model cannot. They should tell customers upfront which models can and cannot be updated before we waste $100.
