C7000 Won't Update via TW/Spectrum

For the most part I agree with your post....certainly the conclusion that we are S.O.L.  However, I don't believe the TW tech person I spoke with about a month ago now was untruthful in saying they had made attempts to update the Firmware and they had failed.  He made multiple attempts while I had him on the line...and each one would show up on my event log as T3 or T4 timeouts and other critical errors.  It was a copy of that log that resulted in Netgear sending me a replacement C7000.  However, as mentioned the replacement had exactly the same out of date firmware!  I DO agree that TW/Spectrum no longer updates a product they do not sell...and that is a recent decision.  Since June 16 there have been NO events on my log that reflects errors and/or timeouts so I think they have, indeed, quite trying.  The fact that they quit trying has improved my original problem which was signal drop outs on the C7000.  The tech had told me that when the Firmware is updated you can and usually do lose connection afterwards until the modem reboots.  I believe, but don't know, that each attempt ultimately took me off-line and there were MANY attempts....at all hours.  So, my problem with drop outs is minimal even though my firmware is out of date.  I have favored Netgear products for years and rarely had a problem.  I started in the old days when the router had a life time warranty.  Now the life of it is unpredictable but when it is over...it's over.  I would not likely buy another Netgear product as a result but right now I don't know which product I would buy.   

Thanks to all for replying.
