Is Docsis 3.1 more susceptible to upstream noise than Docsis 3.0?
I've been a Cox customer for 22+ years. I've rarely had any issues. A few years back, I had had voltage on my upstream and they replaced a cable from my house to the pole. But other than that, no issues at all. I had a 16x4 Docsis 3.0 Netgear modem. Was on the 300/30 plan. It was pretty fast, like I said, no issues. So last week I got the email blast about upgrading to Docsis 3.1, figured I would go ahead and pull the trigger. It worked blindingly fast for the first day or so, was getting around 850 down and 34 up consistently, no issues. Then it started dropping to nothing. Every day since then, still getting about 750-850 down, but only getting 0-10 up. It says I have between 40-60% packet loss. Constant disconnects. Cox is telling me there is "noise" on the upstream line. So what changed between me having Docsis 3.0 and switching to Docsis 3.1? I have a Motorola 8600 modem. Is Docsis 3.1 more susceptible to noise?
Upstream / Upload issues leading to huge ping spikes
I've done everything I can on my end to mitigate the issues im having. All new coax in home. One brand new 2 way splitter for cable modem and TV box (-3.5db) All connections are firmly tightened and secured. Docsis 3.1 32x8 (2x2). Signal levels all in range T3 timeouts on event log. Cox has tested my lines in home and at the road. They say all it fine. Cox runs a ping plotter in my area...again, all is fine. My issue is terribly fluctuating upload speeds and this leads to drastic ping spikes which massively effects my gaming. Since cox has no idea what they are doing... is there anything I can do to mitigate this? I was doing some research and I saw this (image attached). Would something like this work? Or is there something that I can implement myself that will fix this issue? Last i heard from cox, they said my neighborhood has "Intermittent Noise Issues" Its been this way for years.. Way before Hurricane Laura Way before Covid 19. I need a miracle....somebody lol /resized-image/__size/320x240/__key/communityserver-discussions-components-files/5/Screenshot_5F00_20200830_2D00_215300_5F00_Chrome.jpg
Upload Speeds Drop At The Same Exact Time Every Night For Months
I have been dealing with an issue now for about 4 months that consists of my internet speeds dropping (mostly upstream) at the same time every night. At about 9:15 pm Central Time my upstream drops to below 1 Mbps from anywhere between 45 minutes to multiple hours. I do streaming on Twitch and spend a lot time gaming so this is my peak hour for these activities and they are greatly affected by this upstream issue. I have had around 7 techs out who have changed everything they can and have ruled out anything wrong at my tap or at my residence. I was eventually given the number to a shift supervisor that I could call when the issue was occurring where I was to leave a message with my name an number and they would look into it and get back the next day. I have stopped receiving callbacks and am at a loss as to what to do next. I have had confirmed packet loss during these periods that I see through the trace routes I run and from the supervisors I have talked to. I was also told by this supervisor and technicians that have been out that congestion should not be an issue as I am the only active subscriber on my tap so that has been all but ruled out. If anyone is willing to give me some direction or work with me I would greatly appreciate it as coming to this forums is my last ditch effort in trying to figure this issue out. Thank you so much for your time.
Only 1 Up Channel Bonded & 51-55 Upstream / Bad Wiring or Buy Modem?
Modem: Netgear C3700-100NAS Connection: No spitters in the house. No TV. Modem combo is connected directly to the coax coming from the wall. Coax from wall is closest to the outside connection. Problem: I'm having some ongoing issues with my modem requiring frequent resets. I believe these problems to be related to my 51-55 dBmv and my only one locked bonded upstream channel. I believe this is a line problem, and not a modem problem Attempted Solution: Cox tech acknowledged my 51-55 dBmv . The tech suggested that i buy a new modem because mine was more than 3 years old. I will post excerpts of this chat log below. The tech offered to send a rented one to me. However, I discovered he modem came with a $20 self installation fee, so I refused this option. If the modem was the problem, i would rather use that $20 to buy a Netgear CM600 or an Arris sb6183 and mate it to an Archer C or A7. Question: Does the tech's suggestion to buy a modem sound right to you?
