If you have a SB6183 running slower with just 4 channels (seen at http://192.168.100.1) you can get full speed and 8 channels back

It took over a week to get to the right folks in support, but eventually the above forum post, mentioned to the @CoxHelp person I was Twitter DM'ing, made all the difference.

Hoping this forum post can help avoid some early adopter pains for other Cox customers who bought a SB6183. Let's hope they add the self-install menu option for this modem soon, so that proper provisioning would be painless.

In their defense, the self install worked for me. It didn't list the modem, but it did pop up with the serial and upon selection brought up the proper modem.

In my research, I referenced your site not knowing that your problem had already been corrected.

I still wish I was getting more than 8 channels, but I'm sure that will change sooner or later. :)

I saw a relevant post on this on DSLR. Seems like its a known issue. Seems the factory firmware doesn't like how the infrastructure is in some area. But should correct itself once the firmware updates.

I am having the same issues. I been trying for over two weeks since upgrading my modem to a DOCSIS 3 SB6183 to get all the downstream channels I am paying for in the premier package. I've had tech guys on site twice and more than a few level 2 tickets. No one seems to know how to get my modem to show more than 4 downstream channels. It doing some internet digging it seems this is a provisioning issues where they need to set it to the right number of channels: http://www.dslreports.com/forum/r29592768-Only-4-downstream-channels~start=30?r=221 and http://www.tinkertry.com/sb6183/ I know I have them available in my area because a cox test modem (CG3000D) showed 8. Anyone know how to get a hold of the right person with the appropriate technical knowledge to fix this? (and no this isn't a bad modem. Over the course of these 2 weeks I've had 6 different modems installed because the cox tech guys said the problem were bad modems...and they all can't be bad...)

A proper fix will be coming for this problem in the near future. If you're having trouble getting the advertised speeds in the meanwhile it may be beneficial to continue using the CG3000 for the time being.
