Just looking around to try to get a feeling for WTF is going on with this ... situation. I can confirm that as of this post IPv6 with (version 8) of the SB6141 is still not working for TWC - Central New York (Syracuse area). 

 

After my last go-round with the local "tier 3" support I find myself almost ecstatic just to hear someone, somewhere, just maybe, perhaps testing with SB6141 v8.0. When I tried to report this "problem" I was told in differing ways that IPv6 didn't work because I was using a cable modem I had purchased not because anything was in any way lacking on the TWC end of the cable. <sigh />

 

Below is an excerpt from my CM log, mostly just for the heck of it. I noticed that the "SW upgrade Failed after download" error is logged following the CM reboot around 14:54, but does not occur during the 15:58 CM reboot. I wonder why? Smiley Surprised 

 

Is there someplace on this forum where I can watch for further status on the progress of the SB6141 v8 testing?

Joining the list, unfortunately.  New SB6141 in Appleton, WI.  Trying to work through with tech support as we speak.  Will keep my efforts updated here.

Seeing the same - not receiving any IPv6 router advertisements, nor receiving any responses to DHCPv6 requests.

 

To be absolutely clear, this is a recommended modem as per TWC's official page at http://www.timewarnercable.com/en/support/internet/topics/lease-or-buy-modem.html .

 

In case anyone from TWC re-visits this thread (TWC-PhilB seems to be MIA since 5/6) - my open ticket # is TRB6008207 in case we can correlate all of this together for a timely solution.

This is a known problem with no specific date of repair.  If you want native IPv6 now you will have lease/buy a modem that has not had IPv6 disabled.  That list does not include the new (HW v8) 6141 or the 6183.

Ugh.  Just for the sake of trying to progress this, do you have any sources you can provide?  (Was this told to you by someone authorititive by TWC?  Any ticket #'s to reference, etc.?)

For a "known problem" there actually does not seem to be all that much to be learned about it. For example, it would be interesting to learn why there is not even hand waving in the general direction of a date of repair. 

 

What is so  intractable about adding support for for IPv6 with these cable modems?

 

Is there any way to help motivate Time Warner to fix this known problem? Man Frustrated

TWC doesn't make the modems and can't fix the problems.

 

If you look at the Arris SB series changelog (posted over at DSLR)  you might wonder why anyone would buy one.

While I know I will almost certainly regret admitting this, I also might learn something so ...

No - but at long as they have listed support for the modem (as they have) - they have more responsibility and control over it then a user does.  If/as new firmware becomes available, TWC as the ISP gets to push whatever firmware to it they choose, and I as the user don't get a say in the matter.

 

The L3 tech I just spoke to "knows" that they are working deployments of the SB6141 w/ IPv6 in northern Ohio - but is unsure about other markets, which is what the ticket I referenced above was opened for to hopefully help investigate.

 

Fortunately, at least I have the luxury of not being invested in this modem (yet).  Right now my challenge to TWC is to advise as to a modem which has working IPv6 support in this market, and I'll get one of them.  For that matter, I'll go drive over to the retail store and get a modem on a temporary lease to try out - but I'm afraid that I'll end up with no better results after that than I am now.  (I won't be surprised if they send me out of the store with a SB6141 for that matter.)  I know a co-worker has a SB6183 with broken IPv6 support that has a story of its own.  It, at least, is unfortunately marked as "Not IPv6 compatible" on the compatibility list.  Imagine my lack of surprise to find that SB6141 is apparently about to end up in the same boat.

 

Furthermore, TWC has an obligation (including maintaining their FCC obligations) to provide support here - including keeping the list of modems at http://www.timewarnercable.com/en/support/internet/topics/lease-or-buy-modem.html updated and correct.  If there are known issues with the SB6141 or other modems here, it must be disclosed as such.  Otherwise the claims at http://www.timewarnercable.com/en/support/internet/topics/ipv6.html could be construed as false advertising.

No - but at long as  ... blah blah blah ...

 


Don't move the goal post.  The question was "Is there any way to help motivate Time Warner to fix this known problem?" and that's what I responded to.  There was nothing in there about FCC obligations or a question about can the end-user fix it or is an out-of-date web page false advertising.

 

Perhaps you're unaware of the fact that cable operators are among the poorest rated utilities in the US for customer support.

Or that all the major players have been called to explain to congress why they do such a bad job.

 

If you are aware of those things then I don't understand why you posted this rebuttal to an assertion I didn't make.
