Any on have cm1200 working on Cox Gigablast ?
I purchased a CM1200 to use on Cox Gigablast the most I can get out of it is 370mb directly connected using speedtest. Anyone have better luck if so what did you do? I'm about ready to return th...
Thanks for the response.
Have you ever gotten gigabit speeds out of your connection? No just added Gigabit
Do you have a screen snip of your connections page? include upload and download connections?
See Attached:
Is your pc capable of maxing out gigabit? Yes - Gigabit Ethernet laptop connected directly to the Modem line 1 no routers etc.
What website are you using for testing? www.speedtest.net
If you have any splitter, attenuators, amplifiers, 90 degree elbows, kinked coax, cheap coax connections, corrosion, then remove these from your line and re-test. None - I installed a brand new Coax line from the modem to the external Cox connection.
Have you checked with your ISP? Yes - I have a tech coming out tomorrow to look at the external lines.
You're screen snip needs the upload and ofdm channels as well.
Just from what I can see, I don't think they partitioned it right or have it seutp right as you only have 20 channels locked on your download. Many ISP's require most to all of the channels and ofdm locked to reach gigabit speeds. Also the power levels you're getting are a bit hot (high).
I'd try contacting them and having them reparition the modem or seeing if your location even has the setup for gigabit capabilities.
Thanks the message would not allow me to post any additional images here is the second half.
Basically comes down to same thing. Not enough channels are locked to reach gigabit speeds. That's something Cox controls (when everything is within power spec) as they send the partitioning and control the cmts . Usually if you've got funky power readings/uncorrectables, it tends to be a signal issue. Your signal is a little high but you not getting a bunch of uncorrectables so I'd be better on the partitioning they sent. Not 100% but its worth calling and having them repartition it.
Sometimes you'll see 31 channels locked with the final one being reserved for the docsis 3.1 channel (ofdm).
Thanks for the response
Good info I have them coming out tomorrow so I'll see what I can get them to do.
I'll update this fourm once it get's resloved.
