A lot of the time theories do not translate into real world experience.There is no guarantee that 50% of the subscribers will be assigned to channels 1-4 and the other 50% channels 5-8. Since I have owned the SBG6580 for 1 1/2 years there has not been any extra congestion for me by being switched to 8 channels from 4. Over this span of time the bonding on my modem has gone from 4x1 to 4x2 and finally 8x4. The only reason to buy older technology is to get it at cheaper price but in this instance it is false economy. The subscriber will just have to buy the same item twice and has not saved any money at all. There are all kinds of erroneous statements about this modem from people that have never owned it.
WOW - and you are basically out of spec for your signal levels and the Motorola keeps you going stable.
That's impressive given the Power Levels you are showing!!
