The last week and a half or so I've been experiencing slow upload speeds (10-17 Mbps). I normally get 29-33 all day long, my plan is a 300/30. Feels like my upload speed is being throttled. My download speeds are roughly in the low to mid 200's (Docsis 3.0 modem) Doesn't matter what part of the day I've tried to run speed tests to verify it hasn't made a difference. Having my modem plugged directly into any of my computers via ethernet vs through a router doesn't make a difference either. Here is signal for my modem DPQ3212
DPQ3212 is not fast enough for 300/30Mbps. As per here, the DPQ3212 is only good up to 100/10Mbps. You need a modem with atleast a 24x8 tuner. You may be eligable for a free upgrade. What state do you live in? I think CA, AZ and VA offer the newer D3.1 phone modem. Otherwise you have to use two modems. The DPQ3212 for phone and another modem like the Netgear CM600 for internet.
With that said, do you notice if your upstream power levels changed when you upload speed went down? My guess is your on a upload channel or two that has congestion. Cox wouldn't throttle just upload if you were approaching your limit since you download so much more then you upload in general. However there is more download bandwidth then upload bandwidth, so you see congestion on the upload first.
I live in OK. I will contact cox and see if I'm eligible for a free upgrade. They sold me this modem when I got their ultimate package of 200/20 a few years ago. Strange that this modem doesn't support past 100/10.
I'm not sure what the signals were before I encountered this issue. Is there a way to change my upload channels that might be possibly congested?
Thank you for helping me out with this issue, I really appreciate it.
Oops. Looks like the new D3.1 phone modem(eMTA) is only available to Gigablast customers, not Ultimate. Also, the three states are AZ, CA, and NV(LV). If you live in any of those three states, you might still be able to talk a employee at one of the stores to trade you one.
Bahh, I just wrote a long post and the forum bug god ate it.
Long story short, try resetting the DPQ3212 with the hole/pin on the back. Hold it for 30seconds, and not the quick 1 second press you used to change between PC and router. It "should" pick the best upstreams available at that time, based on use and your signal levels upstream. Also, anything you can do to lower your upstream a few points might help, even though your levels in general aren't bad.
However, either way I suggest a new modem. I don't think the new phone modem is available in your area so you would need to use a splitter for a second modem. This would make your upstream even higher, which is not optimal. Are there any splitters else where in the loop you can remove before the modem?

Keep in mind I am just going by what is official. If your local Cox store happens to have one, and you can talk them into it, anything is possible. Also, someone in sales might be able to send you one in the mail so don't hesitate to call. I will keep my fingers crossed, because the upgrade would be the optimal solution.
