Modem hardware requirements for upload speed

Creating a new post of a discussion started here. Does anyone have any insight into what the hardware or network requirements are for the different upload speeds? For example, as per here, the uploa...

    Still doesn't answer the difference between 10 megabits and 50 megabits. This is sad. This is why I missed DSL reports. I guess I just won't be able to help people who have problems with their upload speed because Cox doesn't know how to troubleshoot it either. 

    This is one of the reasons I don't believe that technical support should always work from home. You get less trending data from the people around you and you can't escalate things to a state of talking face to face. It's all emails and phone calls where people can BS you. Just another reason why the system Cox calls support doesn't work.

Hi,

When a new customer signs up for service the "up to" upload speed is disclosed to that person in the order summary before they complete the order. If the upload speed increases while they are a customer they will receive a notice of this. Colleen has reached out for a better explanation that can be provided and we will update it here as soon as we have more information to share.

    I know you can use the broadband labels to see what the upload is in your area, but that doesn't tell you what is technically required. For example, if a area offers higher upload because it has a OFDMA channel, then you would need a D3.1 modem to take advantage of it. If the area is mid split, you might need a modem with a switchable upstream filter the Arris S33. However Comcast only offers the highest speed to modem's they have specially been tested for that speed on their network. IE, the S33 isn't supported for 200Mbps on Comcast, but the S34 is, even though hardware wise they are similar/identical. Is Cox like this too?

    Hopefully Colleen can find someone who can shed some light on this question.

      When a new customer enters their address on our site it will only offer speeds available at that location. The same would go for a current customer who signs into their account on cox.com. The broadband facts label will confirm the available speeds. This all happens on the back end based on the network architecture you referenced from the published speed info. I hope this sufficiently answers your question, as it's the only information we have available.

        So are you saying that a customer can get 50Mbps upload on the 500Mbps tier as long as the labels and Cox system find it is available in the area? Any DOCSIS 3.0 and above device will work?
