Netgear CM1200 is 32×8
Downstream Light: Blinking Green (Scanning for additional downstream channels)
I don't know why the Downstream would be blinking because you have 32 locked channels.
Your Upstream, however, only has 4 Bonded Channels. I'd assume...due to gigabit...you should have 8. Your Upstream Light should be blinking.
dave9 would be the best source but I think the OFDM(A) channels are your overall circuits. These circuits are then divided into separate channels: 32 and 4. Therefore the overall circuits wouldn't be individually locked. I could be wrong and sure I am.
I guess a good question: why don't you have 8 Upstream channels?
Hi Bruce, I appreciate the response.
I am not sure why I don't have 8 upload channels locked but at this point Cox has decided that now my brand new modem is also the "Issue". The issue has been consistent through my Netgear CM1200 as well as the Netgear CM2000 modem I just purchased two weeks ago. The concerning part for me is they installed one cox modem and it actually wouldn't lock the downstream channels either. They said their modem must have an issue as well. So now we are on a forth modem(another cox modem) to see if they can pinpoint the issue. After provisioning it did lose connection but I was told it was probably upgrading the firmware so that is why it was down.
I hate to sound negative but I find it very hard to believe that 3 out of 4 different modems(including one of cox's) are the issue and not something with the signal.
I now seem to have the ODFM channel locked as of this morning (after 12 hours) but there the SNR and power levels don't have any readings. Shouldn't there be some kind of signal information?
Any thoughts on this? This is from cox modem model # CGM4140COM
