VERY SLOW UPLOAD SPEEDS, download is fine.
I have been dealing with extremely slow upload speeds for a very long time, at least a year. Maybe two? I have gigablast. Download is consistently fine. Always around 900 mbps and above. Upload is sp...

with ping plotter, you have to watch for packet loss in the cox hops, then look for packetloss on the very last hop. also check your upstream and downstream signals, Good Downstream power level are within -7 to +7 dBmV. Good upstream power levels are within 38-48 dBmV. if you dont know how to see that, go to 192.168.0.1 (if you are using a cox modem/router) not too sure how to do on an aftermarket router. Click "Connection" and go to "Cox Network" and scroll all the way down, and find Downstream and upstream power levels. and check if they are in those ranges.
Thanks Zurq, always some good info. My Netgear C6900 had 24 channels, download power -8.9 to -13.8. My upload had 4 with results of 48.4 to 50.4. So by your standards of +-7 and 38-48, I'm outside the ranges of being Great, maybe Fair. The Home screen shows the Cable Connection as Good. Is there a Better, Great or Excellent indicator here?
I've tighten my modem coaxial connection, including the 1 splitter, and wall, and have power restarted the modem. Does this imply my Modem is going bad, one that I purchased but on the COx list. Since I don't really have issues, other than noticing my upload speeds dropping to half the 2week ago numbers when using the COX speedtest. Other speed test give higher uploads. Also did a pingplotter to the cox site, and showed #6 with lager packet loss. But Cox said my modem had issues, and did not want to discuss the Hop issue I saw. Cox also would not share the IP address that their OCounty speed test was pointing to so that I could have run a ping or pingplotter to it instead of speedtest. WinMTR also had same #6 PLoss like pingplotter did.
by your power levels your modem seems to be running well. If you have a cox modem i'd just go to the cox store and get a new one just to rule it out. I added my own router instead of using the cox modem/router, and make sure if you do have a cox modem/router combo you must put it in bridge mode, it works best for me if you do. and Cox has been effed up for a while if I run a speed test on cox servers it gives me 5 upload it must be something on their end, also turn qos on your netgear router. it helps. and if you want to be 1000% sure it's their end if you are under warranty replace the Netgear C6900. and if you want to test ever further test the speeds and ping plotter wtih the panoramic modem/router. then build a case and escalate it to COX or the FCC make notes take screenshots, so you can show them it isn't your equipment, nor anything you are doing wrong to impact the Quality of the Service.
and if you run a speed test, open up task manager, and go to performance and click network and the send and receive speeds are your upload and download and it should show correct speeds. if it doesn't then you might have a hardware problem.
