Wrong CM1100 Firmware

Netgear says the CM1100 current firmware should be V6.01.07. The modem reports that the installed firmware version is V7.01.01, which is the correct firmware for the CM1000. I have done the factory reset. I have occasional network drops from Comcast, otherwise near claimed speed and "clean" signals.

 

Question: should I expect problems running V7.01.01 on the CM1100? 

My hardware version is V2.02, from the Admin info page.

Thanks for any help.

    Then you need to contact CC and have them double check your modem to be sure they have pushed the right version to the CM1100:

    They need to check on these conditions and logs your seeing aswell.

    If only I could reach them...

     

    i've just spent 2 hours, first with Comcast, then at the end with a Netgear rep.

     

    The Comcast people at five different levels said they couldn’t do it, and referred me to a Netgear rep “expert” who wanted to sell me a year Tech Support subscription. The most helpful person was the on-line chat person (level 2) who responded after navigating the Comcast chatbot. He checked signal levels, etc., said it looked good from his end but couldn’t help with the firmware provisioning. He scheduled a call-back with the next level. Unfortunately, the call-back was identified by Verizon as spam and directed immediately to voice mail. After checking voice mail, I reached a Comcast person (level 3) who wanted to send a tech out to help me update my firmware. The next Comcast person level (4) agreed with level 3 that Comcast didn’t control the firmware provisioning. After much protesting, this person sent me to level (5) after another person at level 4 came on the line to tell me that the previous person was wrong, and that the problem was because I was using customer-owned equipment. Since it was a Netgear product, they would send me to a Netgear specialist. She didn’t mention that the person was employed by Netgear; the implication was that she was a Comcast employee who “knew” Netgear products. So I was sent to the subscription salesperson. When I declined, she said she would send an article to “help me update the firmware.” The article was about routers, not cable modems.

     

    Netgear’s info pages state unequivocally that only the ISP can provide (or update to) the correct firmware, and shows V6.01.07 to be the latest version. I  am planning to write a letter to Comcast. I could try the phone tree again, but it seems that the chances of reaching the router-provisioning level are very slim.

     

    Thanks to all who responded, stay well, and Happy Thanksgiving.

  • FYI. Only the ISP updates firmware on your modem. I have Comcast and they have never updated firmware on 3 different Netgear modems I have used. I also never had a modem issue so never felt the need to ask them about it. There is no way for you to update.

      labatt,

       

      Yes, I understand that Comcast pushes the firmware. I was asking if the installed version could contribute to the problem of occasional (days to weeks between) connection drops.

      Thanks for the reply.

        I would more likely suspect an issue with the ISP then the modem with that frequency of failures. Look at the signal values coming from the ISP when logged into modem then do a little research about what they should be. May find you are boderline.
