Upload speeds not working as advertised
I have had issues with my upload speeds being no where near advertised for months. To be honest, I'm not sure if I was ever getting full upload speeds. I'm an Ultimate package subscriber, in my area that means I should be getting 200 Mbps down and 20 Mbps up. In reality, I'm getting close to the 200 down but average only about 2.5-3 Mbps up. I switched to the Ultimate package about 2 weeks ago from the 100/10 package in hopes that my upload speeds would improve but they have actually remained the same.
I moved into this house in late 2014 and it's a brand new construction, meaning all the cabling and everything from the street and throughout the house is less than 2 years old. I do not have any TV nor was any ever hooked up. The tap from the street runs directly into the house, directly into my modem via coax and into my modem. There are no further splits or devices in the house connected to a coax hookup, at least that I'm aware of.
This is deeply troubling because the whole reason I upgrade my package was for the upload speed increase, not for the download speeds. I understand it is advertised to be UP TO 20 Mbps, but I'm averaging less than 25% of that. I regularly work from home or send large files between my work and home computers. I also stream media from home to work via Plex and routinely have to limit the stream to 2 Mbps or less to avoid buffering. Finally, I'm an avid online gamer and have been dabbling in twitch streaming.
My experience is very similar to this thread here: http://forums.cox.com/forum_home/internet_forum/f/5/t/12573.aspx?pi287=4. I can do a speedtest.net or Cox speed test and it will indicate 20 Mbps upload. But I can immediately to a testmy.net or speedof.me test and get less than 5 Mbps. This is further supported by the network test on the Xbox one showing similar slow upload speeds as the testmy.net or speedof.me. I have had an upload speed test running every 15 minutes for about 12 hours at testmy.net and got on average a 3 Mbps upload with only one singular test hitting 20 and one other at 11. Everything else has been 8 Mbps or lower.
My equipment: Surfboard SB6190 modem, Netgear Nighthawk R7000 router. My computer is wired directly to the router via cat6 cable, the router is also cabled to the modem via cat6. I get the same speeds regardless of whether I'm wired to the router or directly to the modem. I experience the same internal latency in the SB6190 modem referenced in the thread I linked, but I was getting the same problems for months when using the SB6141. I highly doubt that is the culprit of my reliably slow upload speeds.
I have upgraded my modem to a 32x16 channel modem to handle the Ultimate tier speeds, even though Cox only offers 24 channels. I also changed all my ethernet cables to cat6 and repeated every test twice (wired to modem or to router) with similar speeds indicated in the tests. When the technician came out to setup the Ultimate package he noticed my upload powers were a little low and indicated he installed something to fix it. I assume its the piece at the rear of the modem that the coax connects to and then is connected into the modem (I apologize I don't know it's name). It did raise the levels from 32/33 range up to 36/40 range, but they have fallen the last few days to the 33-37 range. I've also had multiple errors in the modem event log such as RCS Partial Service, SYNC timing Synchronization failure, Lost MDD Timeout, and T3 timeouts.
As you can see, I've tried about everything I can think of on my end. I've upgrade to about the best residential equipment I can afford and seen very little improvement. On the continuous speed test, I even had speeds drop below 1 Mbps for the entire hour between 3-4 a.m. when you would expect there to be the least congestion on the network. This has made online gaming a nightmare at times and severely reduced the quality of my media stream from home.
Below I'll post all relevant data I can think of. Any assistance is greatly appreciated but I'm very skeptical that anything can be done here. I'm nearly positive this is a hardware issue outside of my home that will require a field technician, but I know you have to start somewhere.
