C3700 Firmware Update
I have a C3700-100NAS N600 Cable Modem with firmware version V1.01.11. I can not establish a PTPP VPN connection to my office. It appears that there is a newer firmware version (2.02.08) that suppo...
You know its bad when I explained my bouncing around between companies to the most recent (rep number 6 I think I'm on now (doesn't caout the 10 Comcast reps I've also talked with)) Netgear rep, and he said we get this all the time... Wait really? So you guys are just ok sending customers around and around looking for answers??? At that point I've had it, told the rep Netgear has lost a customer and his response was just "ok that is fine" So I guess Netgear just really doesn't care at all.
I even got both the Comcast rep and the Netgear rep on a conference call together, and not only is the issue not solved, but the Netgear rep was rude to the Comcast rep. Really? We are trying to solve problems, not make more.
Good bye Netgear, I'm moving on to a company that actually cares about its products and customers
I probably spoke with 10 reps from Comcast before I found one that knew how to upgrade my firmware, and he did it right away. It seems to be a lottery. You just have to keep calling. When someone says that Comcast can't help and it must be done by Netgear, politely say thanks, hang up, and call again. I spent way too long on hold, and this is a terrible system, but it eventually worked for me.
Very strange issue observed with C3700. Today (06/29/17) at approx. 1:30 PM The C3700 lost its settings and defaulted back to its factory settings without My intervention. I purchased this unit couple years back, and use it with TWC service. I contacted TWC and the technician I spoke with indicated they did not push out any new firmware and that they do not have the ability to push it out because its not a supplied unit. I informed the technician that I had no way to perform the firmware update myself, as I was informed by Netgear Tech. Support that only ISP can perform the update and push it out. The TWC technician still clamed no updates were performed on thier end. So, it appears that either the technician is mistaken and un-aware of some other TWC process that is performing the update, or My C3700 was expoited by unknown actor. I decided to take the unit offline to perform a manual reset to factory defaults, and re-initialize the settings. All appears OK now, however I still have concerns that the router has suffered a breach. Circumstances like this, and not having ability to perform own firmware flash to ensure integrity of the unit is a cause of concern. Remember, I was informed no updates were pushed out by ISP technician, and I certainly do not have access to the firmware, even though I bought the unit Myself. So its anyones guess who performed the push. One thing is for sure, the C3700 rebooted itself back to factory settings, and lost all configuration. And Yes I did make a backup, but thats not the point. If some unknown actor performed the update, who knows what actually is in the firmware? Remember, the ISP Tech. indicated they did not perform the push of firmware, so who did?
Hello sysatek
The ISP CMTS server pushes the firmware to the modem typically in the middle of the night it will push it and then cause the modem to reboot and it will be up to date. So yes the iSP does the update but the Tech himself can not do it typically it is just uploaded on there server and pushed automatically during maintenance periods.

I understand that the Tech does not push the firmware updates, however the issue I described relates to the router reverting back to factory defaults without My intervention. The ISP Tech indicated they did not push out update, and I certainly do not have the flash image to perform the update Myself, so the point I was making was that either the Tech was unaware of an update process inside the ISP or the update was pushed by unknown actor, or possibly even no flash was pushed at all, and might imply a breach in the products security, and hence they left it freshy tainted for me to see. The unit is not an ISP provided unit, as I purchased the unit and initally setup the config and passwords and such. So finding the unit defaulted to factory settings is a real cause of concern. Imagine if it was your device on your LAN and the ISP indicated they performed no intervention. Would you have any confidence is the security of the device?
