new 500/50 10% plan

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

results.

I don't have an amp in line for the Internet but there is a splitter that cox installed splitting the line

going to an amp for the cable tv.    The other line from the splitter goes straight to the modem.

My download speed is almost 600   but the upload as of today after power cycling the modem

still at 10-12 upload.

I show all 4 upload channels on my SB6190 modem.  I tried cycling several times and I had cox send a reset hit to the box.  It's still 500/10.    Unfortunately COX Internet Tech does not have the same information the 2 COX stores have concerning the upgrade from 500/10 to 500/50 at no additional cost.

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. 👍

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.

I didn't get a chance to check the speed yesterday.  I had some problems with

the account causing me a problem setting up the modem router the way

I wanted it.  Next visit I will check out the speed with a direct connection.

I also may put the COX modem router in bridge mode to confirm it works

the way I need it to work with my personal router should I need to get

the COX modem at my home. 

Getting back to my SB6190 modem,  a few years ago I had the 300/30 plan.

I easily got the 30 upload speed consistently.  Saying that, I know I can do 30 up.

It's possible the problem could be communications from the sales Rep knowing

when it will be available in my area.  As I mentioned a friend has their latest

Panoramic modem/router and even after several power cycling he still has

only 500/10. I stopped by my brother's house who has a COX modem with the 500/10 plan and he does not get 50 up.  I plan this week to stop by another COX store and see what info I can get on this. 

If you friend has a DOCSIS 3.1 gateway, can you check if they are getting upstream OFDM channel?

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.

My SB6190 is a 32x8 modem.   COX Technical told me my modem could handle the 50 up.

At the moment my COX account is still showing 500/10.   I am hoping its just not available in my city. My friend about 10 miles away in a different City just got upgraded at no cost to 500/50.

Hi and thank you for your reply..

According to the MFG and one of the COX Techs I spoke with about a year ago,

the specifications of the SB6190 (32x8) exceeded the 50 upload speed.  If you do a quick google

search on a SB6190 it stating 262mbps upload speed.    Also if as you say it is good for only 10 up

then this confuses me because just a few years ago I was on a plan that offered 300/30 and I had

no problems with the 30 upload in fact I never went below 30 upload and was always higher than the 30.   Unfortunately I have to end that plan because of increased pricing of my cable TV.

This has me baffled when the specs say it can easily handle 50 up,  I used to have 30 up, and now all of a sudden its only good for 10 up?    The other thing my account is still showing my plan as 500/10.   I was told by 2 COX stores to keep an eye on my account.  When it changes to 500/50 the new upload speed would be available to me.   

Thanks for your reply.    My worst case is use one of their modem/routers in what I believe is called "bridge mode" letting me take the output of the modem router and feed a stand alone Router. I don't believe COX is still charging a rental feed for modems.  I have a complicated config of WiFi cameras, thermostat and other devices requiring port forwarding and I just as soon stay with my working router.   It has GigaBit ethernet ports and the WiFi is fast enough.

While it's capable of it, the technology Cox uses to achieve 50mbps up, requires a D3.1  modem. Because yours is a 3.0, you are limited to the 10mbps up. It's like a car in Hampton roads, on the I64 interstate. If you have 2 or more people, you can travel in the HOV lane at a faster rate of speed than the other lanes. While ALL of the cars are capable of the faster speed, only those who meet the specifications, (2 or more people), are allowed to be on the HOV lanes at 10MPH faster than the standard lanes.  Your modem is capable of faster speeds, BUT the transmission method Cox uses, requires a certain specification that your modem doesn't meet, so it has to run at the slower speeds. 

To  add to the confusion,  I received an email from cox@help.   I was told in the email

my  32x8 modem will handle the 50 up.   I guess will just have to wait until my account shows

I have 500/50 and see what happens.
