How many upstream channels should I have ?
I have COX INTERNET PREFERRED 50 service with advertised speeds up to: 50 Mbps download and 5 Mpbs upload
For the past year or so I have noticed that I am only getting 1 out of 4 upstream channels ...

I failed to look closely at your log files. You're only supposed to have 1 channel per stream.
The header in Column-3 of your log reads 64QAM. Only DOCSIS 2 modems support 64QAM (modulation).
As a comparison, DOCSIS 3.x modems support 128QAM upstream. Therefore, not only can a D3 modem bond multiple channels, but also double the bandwidth of each channel of a D2 modem.
D2 may be all you need with a 50 Mbps plan. If your plan has 5 Mbps up, that is well within the capabilities of older modems at 10 or 30 Mbps...even on only one channel. I'm curious of your download speeds. Are you getting 50 or 40 Mbps? D2 is supposed to max at 40 Mbps.
