new 500/50 10% plan

I am getting conflicting information.   The Sales Rep at my local COX store told me anyone with 500 down will now be getting 50 up with that plan.

It's written on an internal memo. 

He called it something like the 10% plan.   I called COX internet customer service on the phone and was told they

knew nothing about it.   My modem is a Surf SB6190.  The bandwidth is 32x8 and the specs exceed both the download

of 500 and the 50 upload.  I see no reason I should not be getting more than my current 10 up. 

A few years ago I used to be on a 300/30 plan but do to cost I downgraded and ended up

with the 500/10 plan.  I easily got both the 300 down and 30 up.

I have a friend  same State and about 10 miles away who uses a COX modem with 500 down and 10 up and he also is not getting

the 50 up.

What's the scoop concerning this.

Thanks,

Ken

    Wait:
    Your modem the SB6190 is only a DOCSIS 3.0, The 50Mbps may require a DOCSIS 3.1 modem. Someone else should chime in and say if I'm correct.
    I just looked it up and DOCSIS 3.0 does not support OFDM. So you will probably never get the 50Mbps. Sorry.๐Ÿ˜ž

      You are correct. You need a DOCSIS 3.1 modem for upstream OFDM and thus 50Mbps upload.

      Thanks for your help lately. It is much appreciated. ๐Ÿ‘

      Even though the SB6190 spec is 262 upload speed?   The modem channel is 32x8.

      Unlike most 24x8 3.0 modems.  The download spec is slightly over 800 and I currently

      get about 600 down.

      It's very difficult to find knowledgable people to talk to when calling COX.  Their Customer Service

      knew nothing of the 500/50 plan.   I checked with a friend who has the latest COX modem

      with currently 500/10.  I told him to reboot the modem.  He still gets 500/10.

      When a COX store rep tells you 500/50 but the on the phone Customer Service person

      says they know nothing of this plan.  How do you get the correct info.

      I picked up a modem yesterday for my summer home and the same sales rep told

      me I will get 500/50.   I'll know in about 6 hours if it's true.  Unfortunately he'll probably

      tell me like he did with my main home to make a service call when I feel confident that

      is not the issue, like in most cases when they come they tell me I'm good inside their home

      and the problem is on the line.

        It's not a matter of what is technically possible, but what Cox will provision and bandwidth efficiency. You need 3 things for the faster upload; D3.1 modem, upstream OFDM and for your area to be "green lit" which basically means the configuration files which control speed on your modems need to be adjusted. Usually this is done on mass 2 weeks after you get the upstream OFDM channel. I suggest asking a friend/neighbor in your area who has a D3.1 modem or new Panoramic gateway(the white one) if they get the faster upload. You can see if your on the same node by looking at the CMTS MAC in your logs. If they get it, you should get it if you decide to upgrade.

    If your node has not been converted to support one Upstream OFDM carrier, you wont get 50Mbps Up
    If you have the Upstream OFDM carrier, then cycle the modem several times, and your Upload should increase to 50Mbps Up

    Also if you are missing all the 4 Upstream QAM channels, (That happened to me.) Cox made a mistake when configuring your node. Post your Diag Signals.

    Also, if you have an RF Amplifier on your line, It will cause serious problems with your Upload. Bypass the Amp with a barrel connector or splitter to separate your modem from the Amp.

    Missing Upstream QAM channels will look something like this:

      How do I insert a picture?  I just looked at my modem status and I can insert the upload

      results.

    Fyi, i get 500+ down and around 27-29 up with the same plan and Docsis 3.0 24/8 modem. My Cox homepage says 500/50, so i guess there's some limit on the upload for Docsis 3.0. I'm not buying a new modem for a bit more upload speed.

      Yup, as stated here, you need a DOCSIS 3.1 modem for the 50Mbps upload. All future speed upgrades will require a D3.1 modem so you will need to upgrade eventually.
