CM1200 doesn't lock onto the OFDM channel, so that is a sign of something wrong going on. A positive thing: the diplexer is set to 85 MHz. That is Cox getting ready for 3.1 in the upstream. :-)

Is 155.93 assigned your router's WAN interface?

It is about how many bits per unit you can transmit. QAM8 is very low modulation. Noise dictates how high it can be. You might not see any problems, because it is this low and therefore can cut through the noisy upstream.

Your downstream numbers are perfect now. I'm just worried about the low modulation in your upstream. If you still have problems, you probably need to talk to your provider. It might not be a problem you can fix yourself.

Hm. My eyes missed the modulation order in your upstream. 64-QAM is common today. It can be lower due to noise. Channel 3 is only 8-QAM in the 2nd picture. Something is going on there. Let's see the stats with the new cable. :)

0 dBmV is said to be ideal (a reference point). -15 dBmV is not really great (and should be avoided) and breaks more easily when noise is present. Your -12 dBmV is not a great value, but your SNR indicates a rather clean line. Unfortunately, your modem doesn't show codeword stats (bit errors)...

Your numbers don't reveal why you are having problems. The modem is operational at -12 dBmV, and your SNR numbers are great. The event log might have more details.

Operators all over the world are building PONs, though, so it is a trend.

In most of their documentation it is called "dual channel asymmetric". They call it single in that link you posted, because you need a very special environment to take advantage of it. In normal use, it just behave as single channel. Flex is something completely else.

Intel has both something called asymmetric and flex. Only flex does you any good.

Newer Intel chipsets tries to optimize such a config, by mixing dual and single channel at the same time. But since ram is so cheap these days, try and check out what is most expensive 2x2 or 2x1 + 2x512

You cannot tweak vista into doing that, Microsoft made sure of that.

Yes, the extra address pins on the cpu also have to be connected to something to be useful. Most modern boards today supports more than 4GB plus memory remapping, so it is not so much a hardware problem anymore that some 32bit OSes don't support more than 4G.
