  • I have two NCS devices (WCB-3000N) and am wondering if they are susceptible to KRACK. If so, when will there be a firmware update for them? If not, could you please post a similar explanation to that on the WCB6200Q article?

  • Jeff,

    The WCB3000N does not support repeater mode or 802.11r FT. So it is not affected by the KRACK vulnerability. So no firmware update is required. But you will need to make sure that your wireless devices themselves are not vulnerable to the KRACK vulnerability. For that, you will need to check with the manufacture of all your wireless devices.

  • How can I downgrade firmware?
    They have Firmware v0.16.8.6 on them now. We want to re flash to version
    Can you provide this firmware version and MOP for re-flashing?

  • Curtis,

    Where did you get those devices with that firmware? Also, where did you hear there was a firmware?

  • I have a customer with a large qty of units with but will not work for them. they are asking me if I can reload to which will work for them.

  • Curtis,
    You are trying to flash the unit with a firmware made for one specific ISP with one made for a completely different ISP. Doing this will cause you to ruin those units. Since those devices were made for a specific ISP the ISP would be the only one you would be able to get the firmware from. Downgrading a firmware on a unit is also something we DO NOT support.

  • I just bought a WCB3000N off Amazon and it has a firmware of v. I am currently setting it up on Cox internet provided Arris TG1682G.
    Am I okay? Or do I need to send this WCB unit back?

  • Gautham,
    That firmware is an ISP specific firmware and programmed to work with that specific ISP. It may be used with other ISP's however, you may experience connection issues requiring the units to be power cycled or reset periodically to connect. That series was also discontinued and the replacement series is the WCB6200Q/ECB6200 MoCA 2.0 adapters.

  • where can I get a download of the latest NCS Firmware to reinstall in my WCB3000N.
    What's in there seams to be corrupted?

  • Joseph,

    There is no way to flash the unit with its original firmware.

  • I bought a few of these off Amazon.  They have firmware v0.16.8.5 and have a Firmware Auto Upgrade button that has a TWC address on it.    In what way would these be a problem to use on a home network that isn't TWC?  I have non-ISP WCB3000Ns in my home and these work just fine with them. 

  • Jeff,

    The problem that you would have is there is no way for you to get the firmware upgrade file if any security updates where released.
