Netgear Bug Slows Comcast's IPv6 Push

Today's cable news roundup starts off with a glitch in Comcast Corp. (Nasdaq: CMCSA, CMCSK)'s IPv6 rollout.

  • Comcast has temporarily reversed part of its nationwide IPv6 deployment upon learning that a retail modem from Netgear Inc. (Nasdaq: NTGR), the CMD31T, ships with an "uncertified version of firmware that exacerbates a critical IPv6-related defect," the MSO said on its IPv6 deployment page. Comcast expects Netgear to patch the problem soon. Mike Demler of EE Daily News brought the issue to light, as he was one of the Comcast customers in California that was stymied by the issue. Comcast's IPv6 migration is among the most aggressive; as of last week, the MSO planned to have deployed the technology in half its network by mid-year. (See Cable Giants Get Aggressive on IPv6.)

  • ClearAccess Inc. has tabbed VP of Solution Sales Jeff McInnis to be CEO of SmartRG, the gateway hardware company that will form after Cisco Systems Inc. (Nasdaq: CSCO) completes its acquisition of ClearAccess and its software-based CPE management and monitoring portfolio. Ken Hood, ClearAccess's founder, is among the 22 ClearAccess employees that will join Cisco. (See Cisco to Buy SPIT Specialist .)

  • Cisco's not getting all the set-top spoils for Videotron Ltd. 's new digital video platform. Samsung Canada is also pitching in with HD clients and HD-DVR boxes to help power the service. (See Cisco, Alticast Box Up Videotron Deal .)

  • Comcast has launched two new features for Xfinity Voice -- text messaging and readable voice mail -- as it seeks new ways to sustain subscriber growth in the category. Comcast Executive Vice President of Data and Communications Services Cathy Avgiris recently discussed the new products with Light Reading Cable, acknowledging that it's time for the MSO "to change things up" with respect to its digital voice service.

  • Comcast has promoted D’Arcy Rudnay to the newly created post of chief communications officer. Rudnay, who joined Comcast in 2003, will retain her title of senior VP of corporate communications and report to Executive VP David Cohen, and work "closely on special projects" with Comcast Chairman and CEO Brian Roberts.

  • Visible World secured a targeted advertisement patent called "Dynamic Bandwidth Allocation for Addressable Content" that describes a technique designed to converge bandwidth when multiple commercials are packed into the same ad spot on a linear TV feed simultaneously.

    No ETA yet from Netgear with respect to how soon they'll get the fix done.  In meantime, here's the rest of  Comcast's statement on the situation:

    <h4>Statement Regarding NetGear CMD31T Devices
    Thursday, March 29, 2012</h4>

    Comcast is in the process of deploying IPv6 nationally, as noted on this site in great detail. We recently identified that the retail NetGear CMD31T device ships with and runs an uncertified version of firmware that exacerbates a critical IPv6-related defect. To ensure Comcast customers with these devices will continue to have uninterrupted Internet service, we have rolled back IPv6 temporarily in some parts of our network to give NetGear more time to address the issue. Comcast anticipates NetGear will soon address the issue for their retail devices, which we will test and deploy on an emergency basis.

    Netgear's confirming that it's working on that patch. There's no ETA on when it will be done, certified and pushed to the subs who were affected (less than 1K, it's believed).&nbsp; but a source familiar with this says the MSO will expedite the process of testing Netgear's new firmware and&nbsp;that both parties are working closely together to get it done as quickly as possible.

    Here's the Netgear statement:

    &ldquo;Recently, some Comcast customers lost their internet connection due to an IPv6 compatibility issue we have with the NETGEAR CMD31T high speed cable modem. We are providing a firmware upgrade to Comcast for certification to make these devices IPv6 capable. As soon as the upgrade is certified, it will be pushed out by Comcast across their network. Resolving this issue for customers in a timely fashion is our number one priority and we are working closely with Comcast on the solution. We apologize for any inconvenience we have caused our customers.&rdquo;
